2118 | All other human gifts can harm us, but not correct reasoning [Leibniz] |
19395 | Philosophy is sanctified, because it flows from God [Leibniz] |
16281 | Honesty requires philosophical theories we can commit to with our ordinary commonsense [Lewis] |
13086 | Metaphysics is a science of the intelligible nature of being [Leibniz, by Cover/O'Leary-Hawthorne] |
21461 | I tried to be unsystematic and piecemeal, but failed; my papers presuppose my other views [Lewis] |
16710 | Leibniz tried to combine mechanistic physics with scholastic metaphysics [Leibniz, by Pasnau] |
12914 | Metaphysics is geometrical, resting on non-contradiction and sufficient reason [Leibniz] |
12780 | We can grasp the wisdom of God a priori [Leibniz] |
5021 | An idea is analysed perfectly when it is shown a priori that it is possible [Leibniz] |
12997 | Analysis is the art of finding the middle term [Leibniz] |
16288 | Analysis reduces primitives and makes understanding explicit (without adding new knowledge) [Lewis] |
15545 | Armstrong's analysis seeks truthmakers rather than definitions [Lewis] |
13099 | Analysing right down to primitive concepts seems beyond our powers [Leibniz] |
8605 | In addition to analysis of a concept, one can deny it, or accept it as primitive [Lewis] |
4465 | Note that "is" can assert existence, or predication, or identity, or classification [PG] |
16897 | Reason is the faculty for grasping apriori necessary truths [Leibniz, by Burge] |
13009 | A reason is a known truth which leads to assent to some further truth [Leibniz] |
19335 | Reasonings have a natural ordering in God's understanding, but only a temporal order in ours [Leibniz] |
5035 | The two basics of reasoning are contradiction and sufficient reason [Leibniz] |
3346 | For Leibniz rationality is based on non-contradiction and the principle of sufficient reason [Leibniz, by Benardete,JA] |
12963 | Opposing reason is opposing truth, since reason is a chain of truths [Leibniz] |
19433 | The universe is infinitely varied, so the Buridan's Ass dilemma could never happen [Leibniz] |
19404 | Necessities rest on contradiction, and contingencies on sufficient reason [Leibniz] |
19360 | General principles, even if unconscious, are indispensable for thinking [Leibniz] |
5042 | For every event it is possible for an omniscient being to give a reason for its occurrence [Leibniz] |
3347 | Leibniz said the principle of sufficient reason is synthetic a priori, since its denial is not illogical [Leibniz, by Benardete,JA] |
4642 | No fact can be real and no proposition true unless there is a Sufficient Reason (even if we can't know it) [Leibniz] |
2098 | The principle of sufficient reason is needed if we are to proceed from maths to physics [Leibniz] |
3646 | There is always a reason why things are thus rather than otherwise [Leibniz] |
2104 | No reason could limit the quantity of matter, so there is no limit [Leibniz] |
19342 | Reason avoids multiplying hypotheses or principles [Leibniz] |
19426 | 'Nominal' definitions just list distinguishing characteristics [Leibniz] |
15457 | Interdefinition is useless by itself, but if we grasp one separately, we have them both [Lewis] |
15527 | Defining terms either enables elimination, or shows that they don't require elimination [Lewis] |
12983 | A nominal definition is of the qualities, but the real definition is of the essential inner structure [Leibniz] |
12915 | Definitions can only be real if the item is possible [Leibniz] |
12982 | One essence can be expressed by several definitions [Leibniz] |
12976 | If our ideas of a thing are imperfect, the thing can have several unconnected definitions [Leibniz] |
12984 | Real definitions, unlike nominal definitions, display possibilities [Leibniz] |
12980 | Genus and differentia might be swapped, and 'rational animal' become 'animable rational' [Leibniz] |
3993 | Arguments are nearly always open to challenge, but they help to explain a position rather than force people to believe [Lewis] |
8627 | Leibniz is inclined to regard all truths as provable [Leibniz, by Frege] |
4686 | Fallacies are errors in reasoning, 'formal' if a clear rule is breached, and 'informal' if more general [PG] |
7415 | Question-begging assumes the proposition which is being challenged [PG] |
7414 | What is true of a set is also true of its members [PG] |
6696 | The Ad Hominem Fallacy criticises the speaker rather than the argument [PG] |
19333 | A truth is just a proposition in which the predicate is contained within the subject [Leibniz] |
12910 | The predicate is in the subject of a true proposition [Leibniz] |
19389 | Truth is a characteristic of possible thoughts [Leibniz] |
19388 | True and false seem to pertain to thoughts, yet unthought propositions seem to be true or false [Leibniz] |
10845 | To be true a sentence must express a proposition, and not be ambiguous or vague or just expressive [Lewis] |
9651 | Verisimilitude might be explained as being close to the possible world where the truth is exact [Lewis] |
15557 | Verisimilitude has proved hard to analyse, and seems to have several components [Lewis] |
5022 | We hold a proposition true if we are ready to follow it, and can't see any objections [Leibniz] |
13157 | Choose the true hypothesis, which is the most intelligible one [Leibniz] |
10847 | Truthmakers are about existential grounding, not about truth [Lewis] |
15546 | Predications aren't true because of what exists, but of how it exists [Lewis] |
15548 | Say 'truth is supervenient on being', but construe 'being' broadly [Lewis] |
15549 | If it were true that nothing at all existed, would that have a truthmaker? [Lewis] |
14399 | Presentism says only the present exists, so there is nothing for tensed truths to supervene on [Lewis] |
10846 | Truthmaker is correspondence, but without the requirement to be one-to-one [Lewis] |
13000 | Truth is correspondence between mental propositions and what they are about [Leibniz] |
2115 | Everything in the universe is interconnected, so potentially a mind could know everything [Leibniz] |
4687 | Minimal theories of truth avoid ontological commitment to such things as 'facts' or 'reality' [PG] |
16456 | For modality Lewis rejected boxes and diamonds, preferring worlds, and an index for the actual one [Lewis, by Stalnaker] |
18395 | Sets are mereological sums of the singletons of their members [Lewis, by Armstrong] |
10807 | Mathematics reduces to set theory, which reduces, with some mereology, to the singleton function [Lewis] |
15496 | We can build set theory on singletons: classes are then fusions of subclasses, membership is the singleton [Lewis] |
15500 | Classes divide into subclasses in many ways, but into members in only one way [Lewis] |
15499 | A subclass of a subclass is itself a subclass; a member of a member is not in general a member [Lewis] |
15503 | We needn't accept this speck of nothingness, this black hole in the fabric of Reality! [Lewis] |
15498 | We can accept the null set, but there is no null class of anything [Lewis] |
15502 | There are four main reasons for asserting that there is an empty set [Lewis] |
10809 | We can accept the null set, but not a null class, a class lacking members [Lewis] |
10812 | The null set is not a little speck of sheer nothingness, a black hole in Reality [Lewis] |
10811 | The null set plays the role of last resort, for class abstracts and for existence [Lewis] |
15506 | If we don't understand the singleton, then we don't understand classes [Lewis] |
15511 | If singleton membership is external, why is an object a member of one rather than another? [Lewis] |
15513 | Maybe singletons have a structure, of a thing and a lasso? [Lewis] |
10813 | What on earth is the relationship between a singleton and an element? [Lewis] |
10814 | Are all singletons exact intrinsic duplicates? [Lewis] |
15497 | We can replace the membership relation with the member-singleton relation (plus mereology) [Lewis] |
15507 | Set theory has some unofficial axioms, generalisations about how to understand it [Lewis] |
10191 | Set theory reduces to a mereological theory with singletons as the only atoms [Lewis, by MacBride] |
15523 | Set theory isn't innocent; it generates infinities from a single thing; but mathematics needs it [Lewis] |
15508 | If singletons are where their members are, then so are all sets [Lewis] |
15514 | A huge part of Reality is only accepted as existing if you have accepted set theory [Lewis] |
10806 | Megethology is the result of adding plural quantification to mereology [Lewis] |
12992 | Logic teaches us how to order and connect our thoughts [Leibniz] |
19370 | 'Blind thought' is reasoning without recognition of the ingredients of the reasoning [Leibniz, by Arthur,R] |
10056 | At bottom eternal truths are all conditional [Leibniz] |
2111 | Falsehood involves a contradiction, and truth is contradictory of falsehood [Leibniz] |
10816 | We can use mereology to simulate quantification over relations [Lewis] |
12974 | People who can't apply names usually don't understand the thing to which it applies [Leibniz] |
15533 | We can quantify over fictions by quantifying for real over their names [Lewis] |
15731 | Quantification sometimes commits to 'sets', but sometimes just to pluralities (or 'classes') [Lewis] |
15525 | Plural quantification lacks a complete axiom system [Lewis] |
15518 | I like plural quantification, but am not convinced of its connection with second-order logic [Lewis] |
15534 | We could quantify over impossible objects - as bundles of properties [Lewis] |
14212 | A consistent theory just needs one model; isomorphic versions will do too, and large domains provide those [Lewis] |
13002 | It is always good to reduce the number of axioms [Leibniz] |
19391 | We can assign a characteristic number to every single object [Leibniz] |
6516 | Monty Hall Dilemma: do you abandon your preference after Monty eliminates one of the rivals? [PG] |
13163 | Circles must be bounded, so cannot be infinite [Leibniz] |
13008 | Geometry, unlike sensation, lets us glimpse eternal truths and their necessity [Leibniz] |
12920 | There is no multiplicity without true units [Leibniz] |
9147 | Number cannot be defined as addition of ones, since that needs the number; it is a single act of abstraction [Fine,K on Leibniz] |
12956 | Only whole numbers are multitudes of units [Leibniz] |
19390 | Everything is subsumed under number, which is a metaphysical statics of the universe, revealing powers [Leibniz] |
19406 | I strongly believe in the actual infinite, which indicates the perfections of its author [Leibniz] |
13190 | I don't admit infinite numbers, and consider infinitesimals to be useful fictions [Leibniz] |

23026 | We know mathematical axioms, such as subtracting equals from equals leaves equals, by a natural light [Leibniz] |
10808 | Mathematics is generalisations about singleton functions [Lewis] |
15524 | Zermelo's model of arithmetic is distinctive because it rests on a primitive of set theory [Lewis] |
15517 | Giving up classes means giving up successful mathematics because of dubious philosophy [Lewis] |

10815 | We don't need 'abstract structures' to have structural truths about successor functions [Lewis] |
15532 | 'Allists' embrace the existence of all controversial entities; 'noneists' reject all but the obvious ones [Lewis] |
15535 | We can't accept a use of 'existence' that says only some of the things there are actually exist [Lewis] |
15789 | Lewis's distinction of 'existing' from 'being actual' is Meinong's between 'existing' and 'subsisting' [Lycan on Lewis] |
10470 | There are only two kinds: sets, and possibilia (actual and possible particulars) [Lewis, by Oliver] |
15520 | Existence doesn't come in degrees; once asserted, it can't then be qualified [Lewis] |
14401 | Every proposition is entirely about being [Lewis] |
12319 | What is not truly one being is not truly a being either [Leibniz] |
12932 | The idea of being must come from our own existence [Leibniz] |
19400 | Possibles demand existence, so as many of them as possible must actually exist [Leibniz] |
19401 | God's sufficient reason for choosing reality is in the fitness or perfection of possibilities [Leibniz] |
7696 | Leibniz first asked 'why is there something rather than nothing?' [Leibniz, by Jacquette] |
19341 | There must be a straining towards existence in the essence of all possible things [Leibniz] |
19428 | Because something does exist, there must be a drive in possible things towards existence [Leibniz] |
5062 | First: there must be reasons; Second: why anything at all?; Third: why this? [Leibniz] |
19393 | What is not active is nothing [Leibniz] |
15540 | You can't deny temporary intrinsic properties by saying the properties are relations (to times) [Lewis] |
15561 | The events that suit semantics may not be the events that suit causation [Lewis] |
15566 | Events are classes, and so there is a mereology of their parts [Lewis] |
15567 | Some events involve no change; they must, because causal histories involve unchanges [Lewis] |
15565 | Events have inbuilt essences, as necessary conditions for their occurrence [Lewis] |
15564 | An event is a property of a unique space-time region [Lewis] |
8607 | Supervenience is reduction without existence denials, ontological priorities, or translatability [Lewis] |

12922 | A thing 'expresses' another if they have a constant and fixed relationship [Leibniz] |
9650 | Supervenience concerns whether things could differ, so it is a modal notion [Lewis] |
3991 | Where pixels make up a picture, supervenience is reduction [Lewis] |
8606 | A supervenience thesis is a denial of independent variation [Lewis] |
16210 | Humean supervenience says the world is just a vast mosaic of qualities in space-time [Lewis] |
19405 | Substances are in harmony, because they each express the one reality in themselves [Leibniz] |
7565 | Leibniz proposes monads, since there must be basic things, which are immaterial in order to have unity [Leibniz, by Jolley] |
5044 | Reality must be made of basic unities, which will be animated, substantial points [Leibniz] |
13174 | A piece of flint contains something resembling perceptions and appetites [Leibniz] |
13175 | Entelechies are analogous to souls, as other minds are analogous to our own minds [Leibniz] |
12747 | Monads are not extended, but have a kind of situation in extension [Leibniz] |
12748 | Only monads are substances, and bodies are collections of them [Leibniz] |
5060 | All substances analyse down to simple substances, which are souls, or 'monads' [Leibniz] |
19377 | A monad and its body are living, so life is everywhere, and comes in infinite degrees [Leibniz] |
19385 | All simply substances are in harmony, because they all represent the one universe [Leibniz] |
12774 | Without a substantial chain to link monads, they would just be coordinated dreams [Leibniz] |
12782 | Monads control nothing outside of themselves [Leibniz] |
12777 | Monads do not make a unity unless a substantial chain is added to them [Leibniz] |

11857 | He replaced Aristotelian continuants with monads [Leibniz, by Wiggins] |
7843 | Is a drop of urine really an infinity of thinking monads? [Voltaire on Leibniz] |
12751 | It is unclear in 'Monadology' how extended bodies relate to mind-like monads. [Garber on Leibniz] |
19363 | Changes in a monad come from an internal principle, and the diversity within its substance [Leibniz] |
19352 | A 'monad' has basic perception and appetite; a 'soul' has distinct perception and memory [Leibniz] |
12966 | Objects of ideas can be divided into abstract and concrete, and then further subdivided [Leibniz] |
15501 | We have no idea of a third sort of thing, that isn't an individual, a class, or their mixture [Lewis] |
15504 | Atomless gunk is an individual whose parts all have further proper parts [Lewis] |
12741 | If experience is just a dream, it is still real enough if critical reason is never deceived [Leibniz] |
12740 | The strongest criterion that phenomena show reality is success in prediction [Leibniz] |
13184 | The division of nature into matter makes distinct appearances, and that presupposes substances [Leibniz] |
13188 | The only indications of reality are agreement among phenomena, and their agreement with necessities [Leibniz] |
12752 | Only unities have any reality [Leibniz] |
14213 | Anti-realists see the world as imaginary, or lacking joints, or beyond reference, or beyond truth [Lewis] |

8909 | Abstractions may well be verbal fictions, in which we ignore some features of an object [Lewis] |
15543 | How do things combine to make states of affairs? Constituents can repeat, and fail to combine [Lewis] |
13187 | In actual things nothing is indefinite [Leibniz] |
16458 | Semantic vagueness involves alternative and equal precisifications of the language [Lewis] |
9057 | Vagueness is semantic indecision: we haven't settled quite what our words are meant to express [Lewis] |
9671 | Whether or not France is hexagonal depends on your standards of precision [Lewis] |
15538 | Semantic indecision explains vagueness (if we have precisifications to be undecided about) [Lewis] |
12993 | Have five categories - substance, quantity, quality, action/passion, relation - and their combinations [Leibniz] |
12989 | Our true divisions of nature match reality, but are probably incomplete [Leibniz] |
10419 | If relations can be reduced to, or supervene on, monadic properties of relata, they are not real [Leibniz, by Swoyer] |
13078 | Relations aren't in any monad, so they are distributed, so they are not real [Leibniz] |

21346 | The ratio between two lines can't be a feature of one, and cannot be in both [Leibniz] |
15751 | Surely 'slept in by Washington' is a property of some bed? [Lewis] |
8571 | Universals are wholly present in their instances, whereas properties are spread around [Lewis] |
15735 | Properties don't have degree; they are determinate, and things have varying relations to them [Lewis] |
9656 | The 'abundant' properties are just any bizarre property you fancy [Lewis] |
15737 | To be a 'property' is to suit a theoretical role [Lewis] |
14979 | Being alone doesn't guarantee intrinsic properties; 'being alone' is itself extrinsic [Lewis, by Sider] |
15454 | Extrinsic properties come in degrees, with 'brother' less extrinsic than 'sibling' [Lewis] |
15742 | A disjunctive property can be unnatural, but intrinsic if its disjuncts are intrinsic [Lewis] |
15397 | If a global intrinsic never varies between possible duplicates, all necessary properties are intrinsic [Cameron on Lewis] |
15398 | Global intrinsic may make necessarily coextensive properties both intrinsic or both extrinsic [Cameron on Lewis] |
15435 | If you think universals are immanent, you must believe them to be sparse, and not every related predicate [Lewis] |
15400 | We must avoid circularity between what is intrinsic and what is natural [Lewis, by Cameron] |
15458 | A property is 'intrinsic' iff it can never differ between duplicates [Lewis] |
15459 | Ellipsoidal stars seem to have an intrinsic property which depends on other objects [Lewis] |
15741 | All of the natural properties are included among the intrinsic properties [Lewis] |
15752 | We might try defining the natural properties by a short list of them [Lewis] |
10717 | Natural properties figure in the analysis of similarity in intrinsic respects [Lewis, by Oliver] |
16217 | Lewisian natural properties fix reference of predicates, through a principle of charity [Lewis, by Hawley] |
8585 | Reference partly concerns thought and language, partly eligibility of referent by natural properties [Lewis] |
8613 | Objects are demarcated by density and chemistry, and natural properties belong in what is well demarcated [Lewis] |
8586 | Natural properties tend to belong to well-demarcated things, typically loci of causal chains [Lewis] |
8589 | For us, a property being natural is just an aspect of its featuring in the contents of our attitudes [Lewis] |
15460 | All perfectly natural properties are intrinsic [Lewis, by Lewis] |
15726 | Natural properties fix resemblance and powers, and are picked out by universals [Lewis] |
14996 | Natural properties give similarity, joint carving, intrinsicness, specificity, homogeneity... [Lewis] |
15743 | Defining natural properties by means of laws of nature is potentially circular [Lewis] |
15744 | We can't define natural properties by resemblance, if they are used to explain resemblance [Lewis] |
15740 | I don't take 'natural' properties to be fixed by the nature of one possible world [Lewis] |
16262 | Sparse properties rest either on universals, or on tropes, or on primitive naturalness [Lewis, by Maudlin] |
15451 | I assume there could be natural properties that are not instantiated in our world [Lewis] |
7031 | Lewis says properties are sets of actual and possible objects [Lewis, by Heil] |
8572 | Any class of things is a property, no matter how whimsical or irrelevant [Lewis] |
15464 | The distinction between dispositional and 'categorical' properties leads to confusion [Lewis] |
18433 | There are far more properties than any brain could ever encodify [Lewis] |
8604 | We need properties as semantic values for linguistic expressions [Lewis] |
15739 | There is the property of belonging to a set, so abundant properties are as numerous as the sets [Lewis] |
15563 | Properties are very abundant (unlike universals), and are used for semantics and higher-order variables [Lewis] |
10723 | A property is the set of its actual and possible instances [Lewis, by Oliver] |
9653 | It would be easiest to take a property as the set of its instances [Lewis] |
14499 | Properties are classes of possible and actual concrete particulars [Lewis, by Koslicki] |
4038 | Properties are sets of their possible instances (which separates 'renate' from 'cordate') [Lewis, by Mellor/Oliver] |
15399 | The property of being F is identical with the set of objects, in all possible worlds, which are F [Lewis, by Cameron] |
15733 | Accidentally coextensive properties come apart when we include their possible instances [Lewis] |
15732 | Properties don't seem to be sets, because different properties can have the same set [Lewis] |
15734 | If a property is relative, such as being a father or son, then set membership seems relative too [Lewis] |
15516 | A property is any class of possibilia [Lewis] |
9655 | Trilateral and triangular seem to be coextensive sets in all possible worlds [Lewis] |
16290 | I believe in properties, which are sets of possible individuals [Lewis] |
9657 | You must accept primitive similarity to like tropes, but tropes give a good account of it [Lewis] |
15433 | Tropes are particular properties, which cannot recur, but can be exact duplicates [Lewis] |
15748 | Trope theory needs a primitive notion for what unites some tropes [Lewis] |
15749 | Trope theory (unlike universals) needs a primitive notion of being duplicates [Lewis] |
15750 | Tropes need a similarity primitive, so they cannot be used to explain similarity [Lewis] |
12733 | Because of the definitions of cause, effect and power, cause and effect have the same power [Leibniz] |
12735 | Everything has a fixed power, as required by God, and by the possibility of reasoning [Leibniz] |
12711 | The immediate cause of movements is more real [than geometry] [Leibniz] |
12959 | We discern active power from our minds, so mind must be involved in all active powers [Leibniz] |
12967 | I use the word 'entelechy' for a power, to include endeavour, as well as mere aptitude [Leibniz] |
13179 | A complete monad is a substance with primitive active and passive power [Leibniz] |
12710 | As well as extension, bodies contain powers [Leibniz] |
13079 | A substance contains the laws of its operations, and its actions come from its own depth [Leibniz] |
12708 | The soul is not a substance but a substantial form, the first active faculty [Leibniz] |
12723 | The most primitive thing in substances is force, which leads to their actions and dispositions [Leibniz] |
12965 | All occurrence in the depth of a substance is spontaneous 'action' [Leibniz] |
12999 | Substances are primary powers; their ways of being are the derivative powers [Leibniz] |
12749 | Derivate forces are in phenomena, but primitive forces are in the internal strivings of substances [Leibniz] |
9476 | If dispositions are more fundamental than causes, then they won't conceptually reduce to them [Bird on Lewis] |
15463 | All dispositions must have causal bases [Lewis] |
15120 | Lewisian properties have powers because of their relationships to other properties [Lewis, by Hawthorne] |
15554 | A disposition needs a causal basis, a property in a certain causal role. Could the disposition be the property? [Lewis] |
13095 | Essence is primitive force, or a law of change [Leibniz] |
12714 | The substantial form is the principle of action or the primitive force of acting [Leibniz] |
12713 | Forms have sensation and appetite, the latter being the ability to act on other bodies [Leibniz, by Garber] |
13087 | The essence of a thing is its real possibilities [Leibniz, by Cover/O'Leary-Hawthorne] |
13169 | I call Aristotle's entelechies 'primitive forces', which originate activity [Leibniz] |
13168 | My formal unifying atoms are substantial forms, which are forces like appetites [Leibniz] |
5056 | Material or immaterial substances cannot be conceived without their essential activity [Leibniz] |
12722 | Thought terminates in force, rather than extension [Leibniz] |
12778 | There is active and passive power in the substantial chain and in the essence of a composite [Leibniz] |
12783 | Primitive force is what gives a composite its reality [Leibniz] |
12969 | The active powers which are not essential to the substance are the 'real qualities' [Leibniz] |
12941 | There cannot be power without action; the power is a disposition to act [Leibniz] |
15461 | A 'finkish' disposition is real, but disappears when the stimulus occurs [Lewis] |
8573 | Most properties are causally irrelevant, and we can't spot the relevant ones. [Lewis] |
15453 | The main rivals to universals are resemblance or natural-class nominalism, or sparse trope theory [Lewis] |
8569 | I suspend judgements about universals, but their work must be done [Lewis] |
15745 | Universals recur, are multiply located, wholly present, make things overlap, and are held in common [Lewis] |
15746 | If particles were just made of universals, similar particles would be the same particle [Lewis] |
21961 | Physics aims to discover which universals actually exist [Lewis, by Moore,AW] |
15436 | Universals are meant to give an account of resemblance [Lewis] |
15747 | Universals aren't parts of things, because that relationship is transitive, and universals need not be [Lewis] |
8576 | The One over Many problem (in predication terms) deserves to be neglected (by ostriches) [Lewis] |
19382 | Abstracta are abbreviated ways of talking; there are just substances, and truths about them [Leibniz] |
15438 | We can add a primitive natural/unnatural distinction to class nominalism [Lewis] |
8570 | To have a property is to be a member of a class, usually a class of things [Lewis] |
8574 | Class Nominalism and Resemblance Nominalism are pretty much the same [Lewis] |
12990 | Real (non-logical) abstract terms are either essences or accidents [Leibniz] |
12939 | Wholly uniform things like space and numbers are mere abstractions [Leibniz] |
13170 | The analysis of things leads to atoms of substance, which found both composition and action [Leibniz] |
12701 | Leibniz moved from individuation by whole entity to individuation by substantial form [Leibniz, by Garber] |
12979 | The only way we can determine individuals is by keeping hold of them [Leibniz] |
12775 | Things seem to be unified if we see duration, position, interaction and connection [Leibniz] |
15455 | Total intrinsic properties give us what a thing is [Lewis] |
12971 | If two individuals could be indistinguishable, there could be no principle of individuation [Leibniz] |
19379 | The law of the series, which determines future states of a substance, is what individuates it [Leibniz] |
13098 | We use things to distinguish places and times, not vice versa [Leibniz] |
12693 | A body is that which exists in space [Leibniz] |
13105 | The laws-of-the-series plays a haecceitist role [Leibniz, by Cover/O'Leary-Hawthorne] |
13075 | No two things are quite the same, so there must be an internal principle of distinction [Leibniz] |
12953 | Fluidity is basic, and we divide into bodies according to our needs [Leibniz] |
12745 | Philosophy needs the precision of the unity given by substances [Leibniz] |
16513 | Identity of a substance is the law of its persistence [Leibniz] |
12699 | A body would be endless disunited parts, if it did not have a unifying form or soul [Leibniz] |
12921 | Accidental unity has degrees, from a mob to a society to a machine or organism [Leibniz] |
12746 | We find unity in reason, and unity in perception, but these are not true unity [Leibniz] |
12035 | Leibniz bases pure primitive entities on conjunctions of qualitative properties [Leibniz, by Adams,RM] |
13160 | To exist and be understood, a multitude must first be reduced to a unity [Leibniz] |
12776 | Every substance is alive [Leibniz] |
19349 | The complete notion of a substance implies all of its predicates or attributes [Leibniz] |
12916 | A body is a unified aggregate, unless it has an indivisible substance [Leibniz] |
12919 | Unity needs an indestructible substance, to contain everything which will happen to it [Leibniz] |
12923 | Every bodily substance must have a soul, or something analogous to a soul [Leibniz] |
12716 | The concept of forces or powers best reveals the true concept of substance [Leibniz] |
13197 | The notion of substance is one of the keys to true philosophy [Leibniz] |
12943 | Individuality is in the bond substance gives between past and future [Leibniz] |
12704 | Aggregates don’t reduce to points, or atoms, or illusion, so must reduce to substance [Leibniz] |
7558 | Substances mirror God or the universe, each from its own viewpoint [Leibniz] |
13161 | Substances are everywhere in matter, like points in a line [Leibniz] |
13171 | Substance must necessarily involve progress and change [Leibniz] |
12756 | Substance is a force for acting and being acted upon [Leibniz] |
13091 | Leibnizian substances add concept, law, force, form and soul [Leibniz, by Cover/O'Leary-Hawthorne] |
11855 | Substances cannot be bare, but have activity as their essence [Leibniz] |
12712 | Substance is that which can act [Leibniz] |
7561 | Substances are essentially active [Leibniz, by Jolley] |
7931 | If a substance is just a thing that has properties, it seems to be a characterless non-entity [Leibniz, by Macdonald,C] |
15537 | If cats are vague, we deny that the many cats are one, or deny that the one cat is many [Lewis] |
12970 | We can imagine two bodies interpenetrating, as two rays of light seem to [Leibniz] |
12986 | The essence of baldness is vague and imperfect [Leibniz] |
15536 | We have one cloud, but many possible boundaries and aggregates for it [Lewis] |
15452 | We could not uphold a truthmaker for 'Fa' without structures [Lewis] |
15448 | The 'magical' view of structural universals says they are atoms, even though they have parts [Lewis] |
15449 | If 'methane' is an atomic structural universal, it has nothing to connect it to its carbon universals [Lewis] |
15439 | The 'pictorial' view of structural universals says they are wholes made of universals as parts [Lewis] |
15441 | The structural universal 'methane' needs the universal 'hydrogen' four times over [Lewis] |
15445 | Butane and Isobutane have the same atoms, but different structures [Lewis] |
15434 | Structural universals have a necessary connection to the universals forming its parts [Lewis] |
15437 | We can't get rid of structural universals if there are no simple universals [Lewis] |
16761 | Forms are of no value in physics, but are indispensable in metaphysics [Leibniz] |
12715 | Leibniz strengthened hylomorphism by connecting it to force in physics [Leibniz, by Garber] |
12700 | Form or soul gives unity and duration; matter gives multiplicity and change [Leibniz] |
15446 | Composition is not just making new things from old; there are too many counterexamples [Lewis] |
14748 | The many are many and the one is one, so they can't be identical [Lewis] |
6129 | Lewis affirms 'composition as identity' - that an object is no more than its parts [Lewis, by Merricks] |
12968 | A 'substratum' is just a metaphor for whatever supports several predicates [Leibniz] |
12697 | Indivisibles are not parts, but the extrema of parts [Leibniz] |
15512 | In mereology no two things consist of the same atoms [Lewis] |
14210 | A gerrymandered mereological sum can be a mess, but still have natural joints [Lewis] |
15519 | Trout-turkeys exist, despite lacking cohesion, natural joints and united causal power [Lewis] |
15521 | Given cats, a fusion of cats adds nothing further to reality [Lewis] |
15522 | The one has different truths from the many; it is one rather than many, one rather than six [Lewis] |
10566 | Lewis prefers giving up singletons to giving up sums [Lewis, by Fine,K] |
9667 | Mereological composition is unrestricted: any class of things has a mereological sum [Lewis] |
13268 | There are no restrictions on composition, because they would be vague, and composition can't be vague [Lewis, by Sider] |
15440 | A whole is distinct from its parts, but is not a further addition in ontology [Lewis] |
15444 | Different things (a toy house and toy car) can be made of the same parts at different times [Lewis] |
14244 | Lewis only uses fusions to create unities, but fusions notoriously flatten our distinctions [Oliver/Smiley on Lewis] |
10660 | A commitment to cat-fusions is not a further commitment; it is them and they are it [Lewis] |
10810 | I say that absolutely any things can have a mereological fusion [Lewis] |
13432 | The essence of a circle is the equality of its radii [Leibniz] |
13088 | Subjects include predicates, so full understanding of subjects reveals all the predicates [Leibniz] |
13077 | Basic predicates give the complete concept, which then predicts all of the actions [Leibniz] |
12908 | Essences exist in the divine understanding [Leibniz] |
12743 | A true being must (unlike a chain) have united parts, with a substantial form as its subject [Leibniz] |
11976 | Aristotelian essentialism says essences are not relative to specification [Lewis] |
12931 | Particular truths are just instances of general truths [Leibniz] |
12811 | We can't know individuals, or determine their exact individuality [Leibniz] |
12981 | Essence is just the possibility of a thing [Leibniz] |
12706 | Bodies need a soul (or something like it) to avoid being mere phenomena [Leibniz] |
12753 | A substantial bond of powers is needed to unite composites, in addition to monads [Leibniz] |
13083 | The essence is the necessary properties, and the concept includes what is contingent [Leibniz] |
13793 | An essential property is one possessed by all counterparts [Lewis, by Elder] |
13082 | The complete concept of an individual includes contingent properties, as well as necessary ones [Leibniz] |
13189 | A necessary feature (such as air for humans) is not therefore part of the essence [Leibniz] |
5057 | If you fully understand a subject and its qualities, you see how the second derive from the first [Leibniz] |
13191 | The properties of a thing flow from its essence [Leibniz] |
11878 | Leibniz's view (that all properties are essential) is extreme essentialism, not its denial [Leibniz, by Mackie,P] |
12906 | Truths about species are eternal or necessary, but individual truths concern what exists [Leibniz] |
12987 | For some sorts, a member of it is necessarily a member [Leibniz] |
12884 | The same whole ceases to exist if a part is lost [Leibniz] |
12781 | A composite substance is a mere aggregate if its essence is just its parts [Leibniz] |
12975 | We have a distinct idea of gold, to define it, but not a perfect idea, to understand it [Leibniz] |
12805 | If two people apply a single term to different resemblances, they refer to two different things [Leibniz] |
12806 | Locke needs many instances to show a natural kind, but why not a single instance? [Leibniz, by Jolley] |
12694 | Essence is the distinct thinkability of anything [Leibniz] |
11862 | Leibniz was not an essentialist [Leibniz, by Wiggins] |
13182 | Changeable accidents are modifications of unchanging essences [Leibniz] |
9663 | A thing 'perdures' if it has separate temporal parts, and 'endures' if it is wholly present at different times [Lewis] |
14737 | Properties cannot be relations to times, if there are temporary properties which are intrinsic [Lewis, by Sider] |
9664 | Endurance is the wrong account, because things change intrinsic properties like shape [Lewis] |
9665 | There are three responses to the problem that intrinsic shapes do not endure [Lewis] |
12972 | Bodies, like Theseus's ship, are only the same in appearance, and never strictly the same [Leibniz] |
19280 | I can ask questions which create a context in which origin ceases to be essential [Lewis] |
19394 | Inequality can be brought infinitely close to equality [Leibniz] |
15968 | Identity is simple - absolutely everything is self-identical, and nothing is identical to another thing [Lewis] |
15969 | Two things can never be identical, so there is no problem [Lewis] |
16504 | Two eggs can't be identical, because the same truths can't apply to both of them [Leibniz] |
5055 | No two things are totally identical [Leibniz] |
13178 | Things in different locations are different because they 'express' those locations [Leibniz] |
19412 | If two bodies only seem to differ in their position, those different environments will matter [Leibniz] |
19411 | In nature there aren't even two identical straight lines, so no two bodies are alike [Leibniz] |
17554 | There must be some internal difference between any two beings in nature [Leibniz] |
8650 | Things are the same if one can be substituted for the other without loss of truth [Leibniz] |
13828 | Necessary truths are those provable from identities by pure logic in finite steps [Leibniz, by Hacking] |
12734 | Every necessary proposition is demonstrable to someone who understands [Leibniz] |
16079 | De re modal predicates are ambiguous [Lewis, by Rudder Baker] |
5047 | The world is physically necessary, as its contrary would imply imperfection or moral absurdity [Leibniz] |
11978 | Causal necessities hold in all worlds compatible with the laws of nature [Lewis] |
12779 | There is a reason why not every possible thing exists [Leibniz] |
13084 | How can things be incompatible, if all positive terms seem to be compatible? [Leibniz] |
5040 | Necessary truths can be analysed into original truths; contingent truths are infinitely analysable [Leibniz] |
4307 | A reason must be given why contingent beings should exist rather than not exist [Leibniz] |
24054 | Everything has a probability, something will happen, and probabilities add up [PG] |
15560 | We can explain a chance event, but can never show why some other outcome did not occur [Lewis] |
14283 | A conditional probability does not measure the probability of the truth of any proposition [Lewis, by Edgington] |
14361 | Lewis says indicative conditionals are truth-functional [Lewis, by Jackson] |
8434 | In good counterfactuals the consequent holds in world like ours except that the antecedent is true [Lewis, by Horwich] |
8425 | For true counterfactuals, both antecedent and consequent true is closest to actuality [Lewis] |
15462 | Backtracking counterfactuals go from supposed events to their required causal antecedents [Lewis] |
12732 | Some necessary truths are brute, and others derive from final causes [Leibniz] |
12978 | A perfect idea of an object shows that the object is possible [Leibniz] |
19432 | Intelligible truth is independent of any external things or experiences [Leibniz] |
17079 | Proofs of necessity come from the understanding, where they have their source [Leibniz] |
2112 | Truths of reason are known by analysis, and are necessary; facts are contingent, and their opposites possible [Leibniz] |
12736 | If we understand God and his choices, we have a priori knowledge of contingent truths [Leibniz, by Garber] |
13159 | Only God sees contingent truths a priori [Leibniz] |
9660 | The impossible can be imagined as long as it is a bit vague [Lewis] |
13172 | What we cannot imagine may still exist [Leibniz] |
15883 | Leibniz narrows down God's options to one, by non-contradiction, sufficient reason, indiscernibles, compossibility [Leibniz, by Harré] |
18822 | Each monad expresses all its compatible monads; a possible world is the resulting equivalence class [Leibniz, by Rumfitt] |
7837 | Leibniz proposed possible worlds, because they might be evil, where God would not create evil things [Leibniz, by Stewart,M] |
19402 | The actual universe is the richest composite of what is possible [Leibniz] |
19434 | There may be a world where dogs smell their game at a thousand leagues [Leibniz] |
9669 | There are no free-floating possibilia; they have mates in a world, giving them extrinsic properties [Lewis] |
16132 | On mountains or in worlds, reporting contradictions is contradictory, so no such truths can be reported [Lewis] |
16133 | Possible worlds can contain contradictions if such worlds are seen as fictions [Lewis] |
12255 | For Lewis there is no real possibility, since all possibilities are actual [Oderberg on Lewis] |
9219 | Lewis posits possible worlds just as Quine says that physics needs numbers and sets [Lewis, by Sider] |
16283 | For me, all worlds are equal, with each being actual relative to itself [Lewis] |
15022 | If possible worlds really exist, then they are part of actuality [Sider on Lewis] |
10469 | A world is a maximal mereological sum of spatiotemporally interrelated things [Lewis] |
18415 | The actual world is just the world you are in [Lewis, by Cappelen/Dever] |
15790 | Lewis can't know possible worlds without first knowing what is possible or impossible [Lycan on Lewis] |
15791 | What are the ontological grounds for grouping possibilia into worlds? [Lycan on Lewis] |
16441 | Lewis rejects actualism because he identifies properties with sets [Lewis, by Stalnaker] |
16282 | Ersatzers say we have one world, and abstract representations of how it might have been [Lewis] |
16284 | Ersatz worlds represent either through language, or by models, or magically [Lewis] |
16286 | Linguistic possible worlds need a complete supply of unique names for each thing [Lewis] |
16287 | Maximal consistency for a world seems a modal distinction, concerning what could be true together [Lewis] |
9662 | Linguistic possible worlds have problems of inconsistencies, no indiscernibles, and vocabulary [Lewis] |
7690 | If sets exist, then defining worlds as proposition sets implies an odd distinction between existing and actual [Jacquette on Lewis] |
12904 | If varieties of myself can be conceived of as distinct from me, then they are not me [Leibniz] |
11981 | If someone's life went differently, then that would be another individual [Leibniz] |
11979 | It doesn't take the whole of a possible Humphrey to win the election [Lewis] |
15530 | A logically determinate name names the same thing in every possible world [Lewis] |
13080 | Leibniz has a counterpart view of de re counterfactuals [Leibniz, by Cover/O'Leary-Hawthorne] |
14404 | The counterpart relation is sortal-relative, so objects need not be a certain way [Lewis, by Merricks] |
5441 | Why should statements about what my 'counterpart' could have done interest me? [Mautner on Lewis] |
5440 | A counterpart in a possible world is sufficiently similar, and more similar than anything else [Lewis, by Mautner] |
16291 | In counterpart theory 'Humphrey' doesn't name one being, but a mereological sum of many beings [Lewis] |
16994 | Counterpart theory is bizarre, as no one cares what happens to a mere counterpart [Kripke on Lewis] |
11974 | Counterparts are not the original thing, but resemble it more than other things do [Lewis] |
11975 | If the closest resembler to you is in fact quite unlike you, then you have no counterpart [Lewis] |
11977 | Essential attributes are those shared with all the counterparts [Lewis] |
13085 | Leibniz is some form of haecceitist [Leibniz, by Cover/O'Leary-Hawthorne] |
11903 | Extreme haecceitists could say I might have been a poached egg, but it is too remote to consider [Lewis, by Mackie,P] |
15129 | Haecceitism implies de re differences but qualitative identity [Lewis] |
9670 | Extreme haecceitism says you might possibly be a poached egg [Lewis] |
5039 | If non-existents are possible, their existence would replace what now exists, which cannot therefore be necessary [Leibniz] |
19424 | Knowledge needs clarity, distinctness, and adequacy, and it should be intuitive [Leibniz] |
19397 | Perfect knowledge implies complete explanations and perfect prediction [Leibniz] |
19332 | For Leibniz, divine understanding grasps every conceivable possibility [Leibniz, by Perkins] |
12960 | We understand things when they are distinct, and we can derive necessities from them [Leibniz] |
12998 | Understanding grasps the agreements and disagreements of ideas [Leibniz] |
16392 | A content is a property, and believing it is self-ascribing that property [Lewis, by Recanati] |
12899 | The timid student has knowledge without belief, lacking confidence in their correct answer [Lewis] |
13006 | Certainty is where practical doubt is insane, or at least blameworthy [Leibniz] |
12897 | To say S knows P, but cannot eliminate not-P, sounds like a contradiction [Lewis] |
12905 | I cannot think my non-existence, nor exist without being myself [Leibniz] |
19334 | I can't just know myself to be a substance; I must distinguish myself from others, which is hard [Leibniz] |
12996 | I know more than I think, since I know I think A then B then C [Leibniz] |
13003 | The Cogito doesn't prove existence, because 'I am thinking' already includes 'I am' [Leibniz] |
3875 | If reality is just what we perceive, we would have no need for a sixth sense [PG] |
12739 | If we are dreaming, it is sufficient that the events are coherent, and obey laws [Leibniz] |
12742 | A whole is just its parts, but there are no smallest parts, so only minds and perceptions exist [Leibniz] |
5509 | Leibniz said dualism of mind and body is illusion, and there is only mind [Leibniz, by Martin/Barresi] |
7568 | Leibniz is an idealist insofar as the basic components of his universe are all mental [Leibniz, by Jolley] |
21253 | Descartes needs to demonstrate how other people can attain his clear and distinct conceptions [Leibniz] |
12929 | All of our thoughts come from within the soul, and not from the senses [Leibniz] |
12933 | Arithmetic and geometry are implicitly innate, awaiting revelation [Leibniz] |
12991 | Children learn language fast, with little instruction and few definitions [Leibniz] |
12940 | What is left of the 'blank page' if you remove the ideas? [Leibniz] |
9344 | Mathematical analysis ends in primitive principles, which cannot be and need not be demonstrated [Leibniz] |
9155 | An a priori proof is independent of experience [Leibniz] |
3876 | If my team is losing 3-1, I have synthetic a priori knowledge that they need two goals for a draw [PG] |
19353 | 'Perception' is basic internal representation, and 'apperception' is reflective knowledge of perception [Leibniz] |
19419 | Not all of perception is accompanied by consciousness [Leibniz] |
15509 | Some say qualities are parts of things - as repeatable universals, or as particulars [Lewis] |
19430 | We know objects by perceptions, but their qualities don't reveal what it is we are perceiving [Leibniz] |
12721 | Light, heat and colour are apparent qualities, and so are motion, figure and extension [Leibniz] |
19358 | Colour and pain must express the nature of their stimuli, without exact resemblance [Leibniz] |
12948 | A pain doesn't resemble the movement of a pin, but it resembles the bodily movement pins cause [Leibniz] |
13005 | Truth arises among sensations from grounding reasons and from regularities [Leibniz] |
12947 | We only believe in sensible things when reason helps the senses [Leibniz] |
4302 | You may experience a universal truth, but only reason can tell you that it is always true [Leibniz] |
12930 | The senses are confused, and necessities come from distinct intellectual ideas [Leibniz] |
2110 | We all expect the sun to rise tomorrow by experience, but astronomers expect it by reason [Leibniz] |
19431 | There is nothing in the understanding but experiences, plus the understanding itself, and the understander [Leibniz] |
5024 | Knowledge doesn't just come from the senses; we know the self, substance, identity, being etc. [Leibniz] |
13001 | Our sensation of green is a confused idea, like objects blurred by movement [Leibniz] |
12898 | Justification is neither sufficient nor necessary for knowledge [Lewis] |
5033 | Nothing should be taken as certain without foundations [Leibniz] |
5020 | Our thoughts are either dependent, or self-evident. All thoughts seem to end in the self-evident [Leibniz] |
19410 | Scientific truths are supported by mutual agreement, as well as agreement with the phenomena [Leibniz] |
16279 | General causal theories of knowledge are refuted by mathematics [Lewis] |
12895 | Knowing is context-sensitive because the domain of quantification varies [Lewis, by Cohen,S] |
19562 | We have knowledge if alternatives are eliminated, but appropriate alternatives depend on context [Lewis, by Cohen,S] |
12949 | Light takes time to reach us, so objects we see may now not exist [Leibniz] |
19392 | I don't recommend universal doubt; we constantly seek reasons for things which are indubitable [Leibniz] |
12785 | Truth is mutually agreed perception [Leibniz] |
12738 | Successful prediction shows proficiency in nature [Leibniz] |
15531 | The Ramsey sentence of a theory says that it has at least one realisation [Lewis] |
15528 | A Ramsey sentence just asserts that a theory can be realised, without saying by what [Lewis] |
15526 | There is a method for defining new scientific terms just using the terms we already understand [Lewis] |
15529 | It is better to have one realisation of a theory than many - but it may not always be possible [Lewis] |
19387 | Hypotheses come from induction, which is comparison of experiences [Leibniz] |
9661 | Induction is just reasonable methods of inferring the unobserved from the observed [Lewis] |
5053 | The instances confirming a general truth are never enough to establish its necessity [Leibniz] |
9652 | To just expect unexamined emeralds to be grue would be totally unreasonable [Lewis] |
15559 | Does a good explanation produce understanding? That claim is just empty [Lewis] |
12913 | Nature is explained by mathematics and mechanism, but the laws rest on metaphysics [Leibniz] |
15556 | Science may well pursue generalised explanation, rather than laws [Lewis] |
15558 | A good explanation is supposed to show that the event had to happen [Lewis] |
9658 | An explanation tells us how an event was caused [Lewis] |
19398 | Minds are best explained by their ends, and bodies by efficient causes [Leibniz] |
4809 | Lewis endorses the thesis that all explanation of singular events is causal explanation [Lewis, by Psillos] |
16280 | Often explanaton seeks fundamental laws, rather than causal histories [Lewis] |
14321 | To explain an event is to provide some information about its causal history [Lewis] |
12755 | Final causes can help with explanations in physics [Leibniz] |
13195 | To explain a house we must describe its use, as well as its parts [Leibniz] |
13089 | To fully conceive the subject is to explain the resulting predicates and events [Leibniz] |
12729 | The cause of a change is not the real influence, but whatever gives a reason for the change [Leibniz] |
13092 | The essence of substance is the law of its changes, as in the series of numbers [Leibniz] |
12977 | We will only connect our various definitions of gold when we understand it more deeply [Leibniz] |
16274 | If the well-ordering of a pack of cards was by shuffling, the explanation would make it more surprising [Lewis] |
13158 | The Copernican theory is right because it is the only one offering a good explanation [Leibniz] |
12737 | Nature can be fully explained by final causes alone, or by efficient causes alone [Leibniz] |
5034 | Mind is a thinking substance which can know God and eternal truths [Leibniz] |
3995 | A mind is an organ of representation [Lewis] |
5045 | No machine or mere organised matter could have a unified self [Leibniz] |
5032 | It seems probable that animals have souls, but not consciousness [Leibniz] |
5054 | Animal thought is a shadow of reasoning, connecting sequences of images by imagination [Leibniz] |
5061 | Animals are semi-rational because they connect facts, but they don't see causes [Leibniz] |
19354 | Leibniz introduced the idea of degrees of consciousness, essential for his monads [Leibniz, by Perkins] |
19438 | Our large perceptions and appetites are made up tiny unconscious fragments [Leibniz] |
12944 | It is a serious mistake to think that we are aware of all of our perceptions [Leibniz] |
19355 | The soul doesn't understand many of its own actions, if perceptions are confused and desires buried [Leibniz] |
2109 | Increase a conscious machine to the size of a mill - you still won't see perceptions in it [Leibniz] |
8209 | Part of the folk concept of qualia is what makes recognition and comparison possible [Lewis] |
15450 | Maybe abstraction is just mereological subtraction [Lewis] |
12951 | Abstraction attends to the general, not the particular, and involves universal truths [Leibniz] |
13193 | Active force is not just potential for action, since it involves a real effort or striving [Leibniz] |
19364 | Volition automatically endeavours to move towards what it sees as good (and away from bad) [Leibniz] |
13183 | Primitive forces are internal strivings of substances, acting according to their internal laws [Leibniz] |
19362 | We know the 'I' and its contents by abstraction from awareness of necessary truths [Leibniz] |
5027 | If a person's memories became totally those of the King of China, he would be the King of China [Leibniz] |
12942 | Memory doesn't make identity; a man who relearned everything would still be the same man [Leibniz] |
12973 | We know our own identity by psychological continuity, even if there are some gaps [Leibniz] |
5023 | Future contingent events are certain, because God foresees them, but that doesn't make them necessary [Leibniz] |
19413 | If we know what is good or rational, our knowledge is extended, and our free will restricted [Leibniz] |
19367 | Saying we must will whatever we decide to will leads to an infinite regress [Leibniz] |
2119 | People argue for God's free will, but it isn't needed if God acts in perfection following supreme reason [Leibniz] |
7841 | We think we are free because the causes of the will are unknown; determinism is a false problem [Leibniz] |
8424 | Determinism says there can't be two identical worlds up to a time, with identical laws, which then differ [Lewis] |
13162 | Sloth's Syllogism: either it can't happen, or it is inevitable without my effort [Leibniz] |
5031 | Everything which happens is not necessary, but is certain after God chooses this universe [Leibniz] |
19368 | The will determines action, by what is seen as good, but it does not necessitate it [Leibniz] |
19409 | Soul represents body, but soul remains unchanged, while body continuously changes [Leibniz] |
12698 | Every body contains a kind of sense and appetite, or a soul [Leibniz] |
5510 | Leibniz has a panpsychist view that physical points are spiritual [Leibniz, by Martin/Barresi] |
12760 | Something rather like souls (though not intelligent) could be found everywhere [Leibniz] |
5025 | Mind and body can't influence one another, but God wouldn't intervene in the daily routine [Leibniz] |
7564 | Occasionalism give a false view of natural laws, miracles, and substances [Leibniz, by Jolley] |
5038 | Assume that mind and body follow their own laws, but God has harmonised them [Leibniz] |
2596 | Maybe mind and body are parallel, like two good clocks [Leibniz] |
5046 | The soul does know bodies, although they do not influence one another [Leibniz] |
19350 | We should say that body is mechanism and soul is immaterial, asserting their independence [Leibniz] |
19421 | Souls act as if there were no bodies, and bodies act as if there were no souls [Leibniz] |
19351 | Perfections of soul subordinate the body, but imperfections of soul submit to the body [Leibniz] |
12727 | It's impossible, but imagine a body carrying on normally, but with no mind [Leibniz] |
7441 | Experiences are defined by their causal role, and causal roles belong to physical states [Lewis] |
7442 | 'Pain' contingently names the state that occupies the causal role of pain [Lewis] |
7444 | Type-type psychophysical identity is combined with a functional characterisation of pain [Lewis] |
3994 | Human pain might be one thing; Martian pain might be something else [Lewis] |
7445 | The application of 'pain' to physical states is non-rigid and contingent [Lewis] |
8579 | Psychophysical identity implies the possibility of idealism or panpsychism [Lewis] |
3989 | I am a reductionist about mind because I am an a priori reductionist about everything [Lewis] |
7443 | A theory must be mixed, to cover qualia without behaviour, and behaviour without qualia [Lewis, by PG] |
7734 | Maybe a mollusc's brain events for pain ARE of the same type (broadly) as a human's [PG] |
7735 | Maybe a frog's brain events for fear are functionally like ours, but not phenomenally [PG] |
18416 | Attitudes involve properties (not propositions), and belief is self-ascribing the properties [Lewis, by Solomon] |
19415 | Passions reside in confused perceptions [Leibniz] |
12935 | Every feeling is the perception of a truth [Leibniz] |
3992 | Folk psychology makes good predictions, by associating mental states with causal roles [Lewis] |
16390 | Lewis's popular centred worlds approach gives an attitude an index of world, subject and time [Lewis, by Recanati] |
3996 | Folk psychology doesn't say that there is a language of thought [Lewis] |
19423 | By an 'idea' I mean not an actual thought, but the resources we can draw on to think [Leibniz] |
19427 | True ideas represent what is possible; false ideas represent contradictions [Leibniz] |
12938 | An idea is an independent inner object, which expresses the qualities of things [Leibniz] |
12945 | Thoughts correspond to sensations, but ideas are independent of thoughts [Leibniz] |
12950 | We must distinguish images from exact defined ideas [Leibniz] |
19357 | The idea of green seems simple, but it must be compounded of the ideas of blue and yellow [Leibniz] |
12995 | The name 'gold' means what we know of gold, and also further facts about it which only others know [Leibniz] |
12807 | The word 'gold' means a hidden constitution known to experts, and not just its appearances [Leibniz] |
3998 | If you don't share an external world with a brain-in-a-vat, then externalism says you don't share any beliefs [Lewis] |
3997 | Nothing shows that all content is 'wide', or that wide content has logical priority [Lewis] |
3999 | A spontaneous duplicate of you would have your brain states but no experience, so externalism would deny him any beliefs [Lewis] |
4000 | Wide content derives from narrow content and relationships with external things [Lewis] |
12911 | Concepts are what unite a proposition [Leibniz] |
19372 | Concepts are ordered, and show eternal possibilities, deriving from God [Leibniz, by Arthur,R] |
11873 | Our notions may be formed from concepts, but concepts are formed from things [Leibniz] |
8901 | Abstraction is usually explained either by example, or conflation, or abstraction, or negatively [Lewis] |
13186 | Universals are just abstractions by concealing some of the circumstances [Leibniz] |
8904 | The Way of Abstraction says an incomplete description of a concrete entity is the complete abstraction [Lewis] |
8938 | The Way of Example compares donkeys and numbers, but what is the difference, and what are numbers? [Lewis] |
8903 | Abstracta can be causal: sets can be causes or effects; there can be universal effects; events may be sets [Lewis] |
8902 | If abstractions are non-spatial, then both sets and universals seem to have locations [Lewis] |
8906 | If we can abstract the extrinsic relations and features of objects, abstraction isn't universals or tropes [Lewis] |
8905 | If universals or tropes are parts of things, then abstraction picks out those parts [Lewis] |
8908 | For most sets, the concept of equivalence is too artificial to explain abstraction [Lewis] |
8907 | The abstract direction of a line is the equivalence class of it and all lines parallel to it [Lewis] |
15443 | Mathematicians abstract by equivalence classes, but that doesn't turn a many into one [Lewis] |
16289 | We can't account for an abstraction as 'from' something if the something doesn't exist [Lewis] |
18418 | A theory of perspectival de se content gives truth conditions relative to an agent [Lewis, by Cappelen/Dever] |
13467 | Leibniz was the first modern to focus on sentence-sized units (where empiricists preferred word-size) [Leibniz, by Hart,WD] |
16278 | A particular functional role is what gives content to a thought [Lewis] |
14215 | Causal theories of reference make errors in reference easy [Lewis] |
14209 | Descriptive theories remain part of the theory of reference (with seven mild modifications) [Lewis] |
8420 | A proposition is a set of possible worlds where it is true [Lewis] |
9654 | A proposition is a set of entire possible worlds which instantiate a particular property [Lewis] |
15736 | A proposition is the property of being a possible world where it holds true [Lewis] |
15738 | Propositions can't have syntactic structure if they are just sets of worlds [Lewis] |
8615 | We need natural properties in order to motivate the principle of charity [Lewis] |
8614 | A sophisticated principle of charity sometimes imputes error as well as truth [Lewis] |
15539 | Basic to pragmatics is taking a message in a way that makes sense of it [Lewis] |
12946 | The idea of the will includes the understanding [Leibniz] |
19331 | Will is an inclination to pursue something good [Leibniz] |
19365 | Limited awareness leads to bad choices, and unconscious awareness makes us choose the bad [Leibniz, by Perkins] |
19343 | We follow the practical rule which always seeks maximum effect for minimum cost [Leibniz] |
12964 | If would be absurd not to disagree with someone's taste if it was a taste for poisons [Leibniz] |
8110 | Leibniz identified beauty with intellectual perfection [Leibniz, by Gardner] |
12925 | Beauty increases with familiarity [Leibniz] |
5063 | Music charms, although its beauty is the harmony of numbers [Leibniz] |
5026 | Animals lack morality because they lack self-reflection [Leibniz] |
7569 | Humans are moral, and capable of reward and punishment, because of memory and self-consciousness [Leibniz, by Jolley] |
13173 | Death is just the contraction of an animal [Leibniz] |
19420 | Death and generation are just transformations of an animal, augmented or diminished [Leibniz] |
19346 | Most people facing death would happily re-live a similar life, with just a bit of variety [Leibniz] |
12958 | Love is pleasure in the perfection, well-being or happiness of its object [Leibniz] |
19340 | Metaphysical evil is imperfection; physical evil is suffering; moral evil is sin [Leibniz] |
12957 | The good is the virtuous, the pleasing, or the useful [Leibniz] |
19366 | You can't assess moral actions without referring to the qualities of character that produce them [Leibniz] |
12927 | Happiness is advancement towards perfection [Leibniz] |
5019 | Supreme human happiness is the greatest possible increase of his perfection [Leibniz] |
5049 | Intelligent pleasure is the perception of beauty, order and perfection [Leibniz] |
12962 | Pleasure is a sense of perfection [Leibniz] |
12934 | We can't want everyone to have more than their share, so a further standard is needed [Leibniz] |
