2. Reason / A. Nature of Reason / 1. On Reason
Traditionally, rational beliefs are those which are justified by reasons [Psillos]
2. Reason / D. Definition / 12. Paraphrase
We could refer to tables as 'xs that are arranged tablewise' [Inwagen]
4. Formal Logic / F. Set Theory ST / 8. Critique of Set Theory
What in the real world could ground the distinction between the sets {A,{A,B}} and {B,{A,B}}? [Inwagen]
4. Formal Logic / G. Formal Mereology / 1. Mereology
Mereology is 'nihilistic' (just atoms) or 'universal' (no restrictions on what is 'whole') [Inwagen, by Varzi]
5. Theory of Logic / D. Assumptions for Logic / 2. Excluded Middle
The 'Law' of Excluded Middle needs all propositions to be definitely true or definitely false [Inwagen]
5. Theory of Logic / E. Structures of Logic / 4. Variables in Logic
Variables are just like pronouns; syntactic explanations get muddled over dummy letters [Inwagen]
5. Theory of Logic / K. Features of Logics / 10. Monotonicity
Valid deduction is monotonic - that is, it remains valid if further premises are added [Psillos]
5. Theory of Logic / L. Paradox / 6. Paradoxes in Language / b. The Heap paradox ('Sorites')
There are no heaps [Inwagen]
7. Existence / A. Nature of Existence / 6. Criterion for Existence
The 'epistemic fallacy' is inferring what does exist from what can be known to exist [Psillos]
7. Existence / C. Structure of Existence / 8. Stuff / a. Pure stuff
I reject talk of 'stuff', and treat it in terms of particles [Inwagen]
7. Existence / D. Theories of Reality / 10. Vagueness / d. Vagueness as linguistic
Singular terms can be vague, because they can contain predicates, which can be vague [Inwagen]
8. Modes of Existence / B. Properties / 5. Natural Properties
Scientific properties are defined by the laws that embody them [Psillos, by Ladyman/Ross]
8. Modes of Existence / C. Powers and Dispositions / 2. Powers as Basic
Powers are claimed to be basic because fundamental particles lack internal structure [Psillos]
9. Objects / A. Existence of Objects / 1. Physical Objects
Material objects are in space and time, move, have a surface and mass, and are made of some stuff [Inwagen]
Maybe table-shaped particles exist, but not tables [Inwagen, by Lowe]
9. Objects / A. Existence of Objects / 6. Nihilism about Objects
Nihilism says composition between single things is impossible [Inwagen]
If there are no tables, but tables are things arranged tablewise, the denial of tables is a contradiction [Liggins on Inwagen]
Actions by artefacts and natural bodies are disguised cooperations, so we don't need them [Inwagen]
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
Every physical thing is either a living organism or a simple [Inwagen]
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
The statue and lump seem to share parts, but the statue is not part of the lump [Inwagen]
If you knead clay you make an infinite series of objects, but they are rearrangements, not creations [Inwagen]
9. Objects / C. Structure of Objects / 3. Matter of an Object
I assume matter is particulate, made up of 'simples' [Inwagen]
9. Objects / C. Structure of Objects / 5. Composition of an Object
If contact causes composition, do two colliding balls briefly make one object? [Inwagen]
If bricks compose a house, that is at least one thing, but it might be many things [Inwagen]
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
I think parthood involves causation, and not just a reasonably stable spatial relationship [Inwagen]
We can deny whole objects but accept parts, by referring to them as plurals within things [Inwagen, by Liggins]
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
Special Composition Question: when is a thing part of something? [Inwagen]
9. Objects / D. Essence of Objects / 8. Essence as Explanatory
The essence of a star includes the released binding energy which keeps it from collapse [Inwagen]
9. Objects / D. Essence of Objects / 11. Essence of Artefacts
The persistence of artifacts always covertly involves intelligent beings [Inwagen]
9. Objects / E. Objects over Time / 7. Intermittent Objects
When an electron 'leaps' to another orbit, is the new one the same electron? [Inwagen]
9. Objects / E. Objects over Time / 9. Ship of Theseus
If you reject transitivity of vague identity, there is no Ship of Theseus problem [Inwagen]
9. Objects / F. Identity among Objects / 1. Concept of Identity
We should talk of the transitivity of 'identity', and of 'definite identity' [Inwagen]
10. Modality / C. Sources of Modality / 5. Modality from Actuality
Actuality proves possibility, but that doesn't explain how it is possible [Inwagen]
10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts
Counterparts reduce counterfactual identity to problems about similarity relations [Inwagen]
10. Modality / E. Possible worlds / 3. Transworld Objects / e. Possible Objects
A merely possible object clearly isn't there, so that is a defective notion [Inwagen]
Merely possible objects must be consistent properties, or haecceities [Inwagen]
14. Science / A. Basis of Science / 4. Prediction
A good barometer will predict a storm, but not explain it [Psillos]
If we say where Mars was two months ago, we offer an explanation without a prediction [Psillos]
14. Science / C. Induction / 4. Reason in Induction
Induction (unlike deduction) is non-monotonic - it can be invalidated by new premises [Psillos]
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
Explanation is either showing predictability, or showing necessity, or showing causal relations [Psillos]
14. Science / D. Explanation / 2. Types of Explanation / e. Lawlike explanations
Just citing a cause does not enable us to understand an event; we also need a relevant law [Psillos]
The 'covering law model' says only laws can explain the occurrence of single events [Psillos]
If laws explain the length of a flagpole's shadow, then the shadow also explains the length of the pole [Psillos]
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
There are non-causal explanations, most typically mathematical explanations [Psillos]
An explanation can just be a 'causal story', without laws, as when I knock over some ink [Psillos]
14. Science / D. Explanation / 4. Explanation Doubts / a. Explanation as pragmatic
Maybe explanation is entirely relative to the interests and presuppositions of the questioner [Psillos]
An explanation is the removal of the surprise caused by the event [Psillos]
15. Nature of Minds / C. Capacities of Minds / 9. Perceiving Causation
It is hard to analyse causation, if it is presupposed in our theory of the functioning of the mind [Psillos]
16. Persons / F. Free Will / 7. Compatibilism
Determinism clashes with free will, as the past determines action, and is beyond our control [Inwagen, by Jackson]
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / j. Ethics by convention
We should follow the law in public, and nature in private [Antiphon]
To gain the greatest advantage only treat law as important when other people are present [Antiphon]
22. Metaethics / B. Value / 1. Nature of Value / b. Fact and value
Nothing is more usual than to apply to external bodies every internal sensation which they occasion [Psillos]
23. Ethics / C. Virtue Theory / 1. Virtue Theory / d. Virtue theory critique
Virtue theory needs an external standard to judge behaviour and character [Inwagen, by Statman]
23. Ethics / C. Virtue Theory / 2. Elements of Virtue Theory / e. Character
The way you spend your time will form your character [Antiphon]
24. Political Theory / D. Ideologies / 2. Anarchism
Nothing is worse for mankind than anarchy [Antiphon]
26. Natural Theory / C. Causation / 1. Causation
We can't base our account of causation on explanation, because it is the wrong way round [Psillos]
Causes clearly make a difference, are recipes for events, explain effects, and are evidence [Psillos]
Theories of causation are based either on regularity, or on intrinsic relations of properties [Psillos]
26. Natural Theory / C. Causation / 2. Types of cause
Three divisions of causal theories: generalist/singularist, intrinsic/extrinsic, reductive/non-reductive [Psillos]
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
If causation is 'intrinsic' it depends entirely on the properties and relations of the cause and effect [Psillos]
26. Natural Theory / C. Causation / 9. General Causation / b. Nomological causation
Empiricists tried to reduce causation to explanation, which they reduced to logic-plus-a-law [Psillos]
26. Natural Theory / C. Causation / 9. General Causation / c. Counterfactual causation
Counterfactual claims about causation imply that it is more than just regular succession [Psillos]
26. Natural Theory / D. Laws of Nature / 3. Laws and Generalities
"All gold cubes are smaller than one cubic mile" is a true universal generalisation, but not a law [Psillos]
26. Natural Theory / D. Laws of Nature / 4. Regularities / a. Regularity theory
Regularity doesn't seem sufficient for causation [Psillos]
A Humean view of causation says it is regularities, and causal facts supervene on non-causal facts [Psillos]
The regularity of a cock's crow is used to predict dawn, even though it doesn't cause it [Psillos]
It is not a law of nature that all the coins in my pocket are euros, though it is a regularity [Psillos]
26. Natural Theory / D. Laws of Nature / 4. Regularities / b. Best system theory
Laws are sets of regularities within a simple and strong coherent system of wider regularities [Psillos]
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / e. Anti scientific essentialism
Dispositional essentialism can't explain its key distinction between essential and non-essential properties [Psillos]
26. Natural Theory / D. Laws of Nature / 9. Counterfactual Claims
In some counterfactuals, the counterfactual event happens later than its consequent [Psillos]
Counterfactual theories say causes make a difference - if c hadn't occurred, then e wouldn't occur [Psillos]
27. Natural Reality / B. Modern Physics / 3. Chromodynamics / a. Chromodynamics
The strong force pulls, but also pushes apart if nucleons get too close together [Inwagen]
27. Natural Reality / F. Chemistry / 2. Modern Elements
Is one atom a piece of gold, or is a sizable group of atoms required? [Inwagen]
27. Natural Reality / G. Biology / 2. Life
At the lower level, life trails off into mere molecular interaction [Inwagen]
The chemical reactions in a human life involve about sixteen elements [Inwagen]
Life is vague at both ends, but could it be totally vague? [Inwagen]
Some events are only borderline cases of lives [Inwagen]
Unlike waves, lives are 'jealous'; it is almost impossible for them to overlap [Inwagen]
One's mental and other life is centred on the brain, unlike any other part of the body [Inwagen]
A tumour may spread a sort of life, but it is not a life, or an organism [Inwagen]
Being part of an organism's life is a matter of degree, and vague [Inwagen]
A flame is like a life, but not nearly so well individuated [Inwagen]
If God were to 'reassemble' my atoms of ten years ago, the result would certainly not be me [Inwagen]
28. God / B. Proving God / 2. Proofs of Reason / b. Ontological Proof critique
There is no reason to think that mere existence is a valuable thing [Inwagen]
