111 ideas
| 18390 | All metaphysical discussion should be guided by a quest for truthmakers [Armstrong] |
| Full Idea: My plea, whatever conclusions are drawn, is to control the metaphysical discussion by continual reference to suggested truthmakers. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 08.7) | |
| A reaction: ...And my plea is to control metaethical discussion by continual reference to value-makers. In general, this is the approach which will deliver a unified account of the world. Truthmakers are the ideal restraint on extravagant metaphysics. |
| 224 | When questions are doubtful we should concentrate not on objects but on ideas of the intellect [Plato] |
| Full Idea: Doubtful questions should not be discussed in terms of visible objects or in relation to them, but only with reference to ideas conceived by the intellect. | |
| From: Plato (Parmenides [c.364 BCE], 135e) |
| 23917 | Contrary statements can both be reasonable, if they are meant in two different ways [Aristotle] |
| Full Idea: Contrary things can be reasonably held …because the contrary positions will stand if what is said is true in one way, but not true in another. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1235b17) | |
| A reaction: My strategy here is to clarify the unambiguous underlying propositions which are being expressed. There will then be either agreement, or flat contradiction. |
| 232 | Opposites are as unlike as possible [Plato] |
| Full Idea: Opposites are as unlike as possible. | |
| From: Plato (Parmenides [c.364 BCE], 159a) |
| 8937 | Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic [Hegel on Plato] |
| Full Idea: Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic. | |
| From: comment on Plato (Parmenides [c.364 BCE]) by Georg W.F.Hegel - Phenomenology of Spirit Pref 71 | |
| A reaction: It is a long way from the analytic tradition of philosophy to be singling out a classic text for its 'artistic' achievement. Eventually we may even look back on, say, Kripke's 'Naming and Necessity' and see it in that light. |
| 18467 | Truth-making can't be entailment, because truthmakers are portions of reality [Armstrong] |
| Full Idea: Truth-making cannot be any form of entailment. Both terms of an entailment relation must be propositions, but the truth-making term of the truth-making relation is a portion of reality, and, in general at least, portions of reality are not propositions. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 02.3) | |
| A reaction: Along with Idea 18466, that seems to firmly demolish the idea that truth-making is a logical entailment. |
| 18468 | Armstrong says truthmakers necessitate their truth, where 'necessitate' is a primitive relation [Armstrong, by MacBride] |
| Full Idea: In a bold manouevre Armstrong posited a metaphysically primitive relation of necessitation, and then defined truth-makers in terms of this bridging relation, as a thing that necessitates something being true. | |
| From: report of David M. Armstrong (Truth and Truthmakers [2004], 02.3) by Fraser MacBride - Truthmakers 1.2 | |
| A reaction: [Not sure of page reference] Spelled out so clearly by MacBride, this sounds dubious. How many truths are necessitated by the City of London? Do truthmakers necessitate the existence of their truths? MacBride says it's a circular theory. |
| 18377 | Negative truths have as truthmakers all states of affairs relevant to the truth [Armstrong] |
| Full Idea: Postulate a higher-order state of affairs, of all the states of affairs in which Theaetetus is involved. Is this not a good candidate for a truthmaker for the negative truth that 'Theaetetus is not flying'? | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 05.2) | |
| A reaction: It certainly seems extravagant to need the whole universe to make true 'there are no lions in this room'. But for 'there are no unicorns' it is not clear which states of affairs unicorns are involved. (Armstrong is aware of this). |
| 18382 | The nature of arctic animals is truthmaker for the absence of penguins there [Armstrong] |
| Full Idea: Each of the arctic animals is by its nature different from a penguin, so this general state of affairs seems truthmaker enough for this negative existential. Similarly, the totality of all birds eliminates the phoenix. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 06.2) | |
| A reaction: Why is it 'animals' in one case, and 'birds' in the other? What if there was no life in arctic? Would the snow then do the job? This doesn't seem to work. |
| 18394 | In mathematics, truthmakers are possible instantiations of structures [Armstrong] |
| Full Idea: A mathematical entity exists if and only if it is possible that there be instantiations of that structure. This transforms the question of truthmakers for the existence of mathematical entities into a question of truthmakers for certain possibilities. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 09.3) | |
| A reaction: This modal approach to structuralism [for which he endorses Hellman 1989] opens up a modal approach to other truthmakers, which places dispositions at the centre of physical truthmaking. No sets of Meinongian objects? |
| 18384 | One truthmaker will do for a contingent truth and for its contradictory [Armstrong] |
| Full Idea: It seems reasonable to say that a truthmaker for a contingent truth is also a truthmaker for the truth that the contradictory of that truth is possible. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 07.2) | |
| A reaction: The truthmaker will have to be not only some fact, but also the additional fact that it is contingent, in order to generate the possibility of the contradictory. |
| 18387 | The truthmakers for possible unicorns are the elements in their combination [Armstrong] |
| Full Idea: The obvious minimal truthmaker for the truth that 'it is possible that a unicorn exists' is combinatorial. The elements of the combination are all that is needed. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 07.5) | |
| A reaction: This seems to imply that there are no possibilities which are not combinations of what currently exists. |
| 18386 | What is the truthmaker for 'it is possible that there could have been nothing'? [Armstrong] |
| Full Idea: It is possible that there could have been nothing. ...What would be its truthmaker? | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 07.4) | |
| A reaction: I suppose the truthmaker here is the whole of reality, with its dispositions and contingencies. But that won't do for 'possibly there might never have been anything'. In such a case there wouldn't be any truths. |
| 18381 | Necessitating general truthmakers must also specify their limits [Armstrong] |
|
Full Idea:
The mereological sum of what happens to be all the men does not necessitate that it is all the men. So if truthmaking involves necessitation, then this object cannot be the complete truthmaker for |
|
| From: David M. Armstrong (Truth and Truthmakers [2004], 06.1) | |
| A reaction: [He invokes Russell has his source] His point is that the truthmaker needs a further fact, beyond the men, which specifies that this is all of them. But only if truthmakers necessitate their truths (as Armstrong claims). I'm sympathetic to both claims. |
| 18396 | The set theory brackets { } assert that the member is a unit [Armstrong] |
| Full Idea: The idea is that braces { } attribute to an entity the place-holding, or perhaps determinable, property of unithood. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 09.5) | |
|
A reaction:
I like this. There is Socrates himself, then there is my concept |
| 18393 | For 'there is a class with no members' we don't need the null set as truthmaker [Armstrong] |
|
Full Idea:
The null class is useful in formal set theory, but I hope that does not require that there be a thing called the null class which is truthmaker for the strange proposition |
|
| From: David M. Armstrong (Truth and Truthmakers [2004], 09.1) | |
| A reaction: It is not quite clear why it doesn't, but then it is not quite clear to philosophers what the status of the null set is, in comparison with sets that have members. |
| 13986 | Plato found antinomies in ideas, Kant in space and time, and Bradley in relations [Plato, by Ryle] |
| Full Idea: Plato (in 'Parmenides') shows that the theory that 'Eide' are substances, and Kant that space and time are substances, and Bradley that relations are substances, all lead to aninomies. | |
| From: report of Plato (Parmenides [c.364 BCE]) by Gilbert Ryle - Are there propositions? 'Objections' |
| 14150 | Plato's 'Parmenides' is perhaps the best collection of antinomies ever made [Russell on Plato] |
| Full Idea: Plato's 'Parmenides' is perhaps the best collection of antinomies ever made. | |
| From: comment on Plato (Parmenides [c.364 BCE]) by Bertrand Russell - The Principles of Mathematics §337 |
| 18392 | Classes have cardinalities, so their members must all be treated as units [Armstrong] |
| Full Idea: Classes, because they have a particular cardinality, are essentially a certain number of ones, things that, within the particular class, are each taken as a unit. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 09.1) | |
| A reaction: [Singletons are exceptions] So units are basic to set theory, which is the foundations of technical analytic philosophy (as well as, for many, of mathematics). If you can't treat something as a unit, it won't go into set theory. Vagueness... |
| 16150 | One is, so numbers exist, so endless numbers exist, and each one must partake of being [Plato] |
| Full Idea: If one is, there must also necessarily be number - Necessarily - But if there is number, there would be many, and an unlimited multitude of beings. ..So if all partakes of being, each part of number would also partake of it. | |
| From: Plato (Parmenides [c.364 BCE], 144a) | |
| A reaction: This seems to commit to numbers having being, then to too many numbers, and hence to too much being - but without backing down and wondering whether numbers had being after all. Aristotle disagreed. |
| 229 | The one was and is and will be and was becoming and is becoming and will become [Plato] |
| Full Idea: The one was and is and will be and was becoming and is becoming and will become. | |
| From: Plato (Parmenides [c.364 BCE], 155d) |
| 21821 | Plato's Parmenides has a three-part theory, of Primal One, a One-Many, and a One-and-Many [Plato, by Plotinus] |
| Full Idea: The Platonic Parmenides is more exact [than Parmenides himself]; the distinction is made between the Primal One, a strictly pure Unity, and a secondary One which is a One-Many, and a third which is a One-and-Many. | |
| From: report of Plato (Parmenides [c.364 BCE]) by Plotinus - The Enneads 5.1.08 | |
| A reaction: Plotinus approves of this three-part theory. Parmenides has the problem that the highest Being contains no movement. By placing the One outside Being you can give it powers which an existent thing cannot have. Cf the concept of God. |
| 18385 | Logical atomism builds on the simple properties, but are they the only possible properties? [Armstrong] |
| Full Idea: One of the assumptions of logical atomism is that all structural properties, all complex properties, are composed of simple properties and relations. ...But does the totality of the simple properties consist of the only possible simple properties? | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 07.3) | |
| A reaction: This refers to what Lewis calls 'alien' properties - possible properties that cannot even be constructed from actual properties. Armstrong's question is about the truthmakers for such things. A bit speculative... |
| 221 | Absolute ideas, such as the Good and the Beautiful, cannot be known by us [Plato] |
| Full Idea: The absolute good and the beautiful and all which we conceive to be absolute ideas are unknown to us. | |
| From: Plato (Parmenides [c.364 BCE], 134c) |
| 18391 | 'Naturalism' says only the world of space-time exists [Armstrong] |
| Full Idea: I define 'naturalism' as the hypothesis that the world of space-time is all that there is. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 09.1) | |
| A reaction: This is helpful, because it doesn't mention the nature of the physical matter contained in space-time, leaving theories like panpsychism as possible naturalistic theories. Galen Strawson, for example. |
| 18374 | Truthmaking needs states of affairs, to unite particulars with tropes or universals. [Armstrong] |
| Full Idea: There must exist states of affairs as truthmakers, to get us beyond 'loose and separate' entities. ...They can be bundles of tropes, or trope-with-particular, or bundles of universals ('compresence'), or instantiations. They are an addition to ontology. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 04.5) | |
| A reaction: Armstrong is the great champion of states of affairs. They seem rather vague to me, and disconcertingly timeless. |
| 18372 | We need properties, as minimal truthmakers for the truths about objects [Armstrong] |
| Full Idea: The 'thing itself' seems not be a minimal truthmaker for the thing having its particular mass. ...The thing has a great many other properties. ...It seems entirely reasonable to postulate that the object has properties that are objectively there. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 04.2) | |
| A reaction: This is Armstrong using the truthmaker principle to argue for the existence of properties (as instantiated universals). I like truthmakers, but truths do not have enough precision in their parts for us to read off reality from them. |
| 18379 | The determinates of a determinable must be incompatible with each other [Armstrong] |
| Full Idea: A set of determinates under the one determinable are incompatible by definition. If an object is not one mile in length, then its actual length will be incompatible with being one mile in length. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 05.2.1) | |
| A reaction: This is a much better general version of the standard example 'if it is red it can't be green'. Armstrong uses it to give a more precise account of incompatibility. Useful. |
| 18378 | Length is a 'determinable' property, and one mile is one its 'determinates' [Armstrong] |
| Full Idea: Length is a 'determinable' property; being some particular length, such as a mile, is one of its 'determinates'. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 05.2.1) | |
| A reaction: The seem to be 'type' and 'token' properties, except that this other vocabulary indicates the link between them. |
| 18373 | If tropes are non-transferable, then they necessarily belong to their particular substance [Armstrong] |
| Full Idea: 'Non-transferable' theories of tropes hold that the mass is of this stone by necessity. It is an identity condition for the property. Every property then becomes an essential property. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 04.3) | |
| A reaction: [He cites Martin and Heil for this view] It is hard to see in this proposal how the trope is in any way separate from its substance, and hence it seems a bit of a vacuous theory. (The other theories of properties aren't much cop either). |
| 18400 | Properties are not powers - they just have powers [Armstrong] |
| Full Idea: Properties are not powers. But properties have powers. They bestow powers. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 10.4) | |
| A reaction: I think this is the wrong way round. In this view, powers become extremely vague things, ranging from the fine-grained to the hugely broad. It seems to me that powers are precise and real, but properties are the vague unhelpful things. |
| 18397 | Powers must result in some non-powers, or there would only be potential without result [Armstrong] |
| Full Idea: Powers must surely issue in manifestations that are something more than just powers. A world where potency never issued in act, but only in more potency, would be one where one travelled without ever having the possibility of arriving. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 10.4) | |
| A reaction: Tricky. The picture I favour is that the distinction between powers and categorical properties is a misunderstanding. What is fundamental is active and powerful categoricals. |
| 18399 | How does the power of gravity know the distance it acts over? [Armstrong] |
| Full Idea: If masses are powers, the forces generated between two particulars have to vary inversely with the square of their distance apart. Have not the masses got to 'know' at what distance they are from each other, to exert the right amount of force? | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 10.4) | |
| A reaction: This seems like a good warning against a simplistic account of powers doing all the work, but I suspect that more sophisticated physics would offer the fan of powers a solution here. The power is to 'spread' the force around. |
| 223 | If you deny that each thing always stays the same, you destroy the possibility of discussion [Plato] |
| Full Idea: If a person denies that the idea of each thing is always the same, he will utterly destroy the power of carrying on discussion. | |
| From: Plato (Parmenides [c.364 BCE], 135c) |
| 227 | You must always mean the same thing when you utter the same name [Plato] |
| Full Idea: You must always mean the same thing when you utter the same name. | |
| From: Plato (Parmenides [c.364 BCE], 147d) |
| 210 | It would be absurd to think there were abstract Forms for vile things like hair, mud and dirt [Plato] |
| Full Idea: Are there abstract ideas for such things as hair, mud and dirt, which are particularly vile and worthless? That would be quite absurd. | |
| From: Plato (Parmenides [c.364 BCE], 130d) |
| 220 | The concept of a master includes the concept of a slave [Plato] |
| Full Idea: Mastership in the abstract is mastership of slavery in the abstract. | |
| From: Plato (Parmenides [c.364 BCE], 133e) |
| 211 | If admirable things have Forms, maybe everything else does as well [Plato] |
| Full Idea: It is troubling that if admirable things have abstract ideas, then perhaps everything else must have ideas as well. | |
| From: Plato (Parmenides [c.364 BCE], 130d) |
| 219 | If absolute ideas existed in us, they would cease to be absolute [Plato] |
| Full Idea: None of the absolute ideas exists in us, because then it would no longer be absolute. | |
| From: Plato (Parmenides [c.364 BCE], 133c) |
| 228 | Greatness and smallness must exist, to be opposed to one another, and come into being in things [Plato] |
| Full Idea: These two ideas, greatness and smallness, exist, do they not? For if they did not exist, they could not be opposites of one another, and could not come into being in things. | |
| From: Plato (Parmenides [c.364 BCE], 149e) |
| 16151 | Plato moves from Forms to a theory of genera and principles in his later work [Plato, by Frede,M] |
| Full Idea: It seems to me that Plato in the later dialogues, beginning with the second half of 'Parmenides', wants to substitute a theory of genera and theory of principles that constitute these genera for the earlier theory of forms. | |
| From: report of Plato (Parmenides [c.364 BCE]) by Michael Frede - Title, Unity, Authenticity of the 'Categories' V | |
| A reaction: My theory is that the later Plato came under the influence of the brilliant young Aristotle, and this idea is a symptom of it. The theory of 'principles' sounds like hylomorphism to me. |
| 218 | Participation is not by means of similarity, so we are looking for some other method of participation [Plato] |
| Full Idea: Participation is not by means of likeness, so we must seek some other method of participation. | |
| From: Plato (Parmenides [c.364 BCE], 133a) |
| 213 | Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once [Plato] |
| Full Idea: Just as day is in many places at once, but not separated from itself, so each idea might be in all its participants at once. | |
| From: Plato (Parmenides [c.364 BCE], 131b) |
| 216 | If things are made alike by participating in something, that thing will be the absolute idea [Plato] |
| Full Idea: That by participation in which like things are made like, will be the absolute idea, will it not? | |
| From: Plato (Parmenides [c.364 BCE], 132e) |
| 215 | If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato] |
| Full Idea: If all things partake of ideas, must either everything be made of thoughts and everything thinks, or everything is thought, and so can't think? | |
| From: Plato (Parmenides [c.364 BCE], 132c) |
| 212 | The whole idea of each Form must be found in each thing which participates in it [Plato] |
| Full Idea: The whole idea of each form (of beauty, justice etc) must be found in each thing which participates in it. | |
| From: Plato (Parmenides [c.364 BCE], 131a) |
| 217 | Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato] |
| Full Idea: It is impossible for anything to be like an absolute idea, because a third idea will appear to make them alike, and if that is like anything, it will lead to another idea, and so on. | |
| From: Plato (Parmenides [c.364 BCE], 133a) |
| 214 | If absolute greatness and great things are seen as the same, another thing appears which makes them seem great [Plato] |
| Full Idea: If you regard the absolute great and the many great things in the same way, will not another appear beyond, by which all these must appear to be great? | |
| From: Plato (Parmenides [c.364 BCE], 132a) |
| 5869 | The thesis of the Form of the Good (or of anything else) is verbal and vacuous [Aristotle] |
| Full Idea: The thesis that there is a Form either of good or indeed of anything else is verbal and vacuous. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1217b20) | |
| A reaction: This is clear evidence for suggesting that Aristotle is a nominalist. Elsewhere his essentialism suggests otherwise, but clearly on grumpy days he thought that universals were mere verbal conventions. |
| 18371 | The class of similar things is much too big a truthmaker for the feature of a particular [Armstrong] |
| Full Idea: For a Class Nominalist 'the class of all 4-kilo objects' is the truthmaker for the truth that the particular has just that mass. Yet this looks far too big! Would not the object still be four kilos even if the other members of the class had never existed? | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 04.2) | |
| A reaction: This seems so obvious to me as to be hardly worth saying. To identify redness with the class of red entities just seems crazy. Why do they belong in that class? Armstrong is illustrating the value of the truthmaker idea in philosophy. |
| 15851 | Parts must belong to a created thing with a distinct form [Plato] |
| Full Idea: The part would not be the part of many things or all, but of some one character ['ideas'] and of some one thing, which we call a 'whole', since it has come to be one complete [perfected] thing composed [created] of all. | |
| From: Plato (Parmenides [c.364 BCE], 157d) | |
| A reaction: A serious shot by Plato at what identity is. Harte quotes it (125) and shows that 'character' is Gk 'idea', and 'composed' will translate as 'created'. 'Form' links this Platonic passage to Aristotle's hylomorphism. |
| 15846 | In Parmenides, if composition is identity, a whole is nothing more than its parts [Plato, by Harte,V] |
| Full Idea: At the heart of the 'Parmenides' puzzles about composition is the thesis that composition is identity. Considered thus, a whole adds nothing to an ontology that already includes its parts | |
| From: report of Plato (Parmenides [c.364 BCE]) by Verity Harte - Plato on Parts and Wholes 2.5 | |
| A reaction: There has to be more to a unified identity that mere proximity of the parts. When do parts come together, and when do they actually 'compose' something? |
| 15849 | Plato says only a one has parts, and a many does not [Plato, by Harte,V] |
| Full Idea: In 'Parmenides' it is argued that a part cannot be part of a many, but must be part of something one. | |
| From: report of Plato (Parmenides [c.364 BCE], 157c) by Verity Harte - Plato on Parts and Wholes 3.2 | |
| A reaction: This looks like the right way to go with the term 'part'. We presuppose a unity before we even talk of its parts, so we can't get into contradictions and paradoxes about their relationships. |
| 15850 | Anything which has parts must be one thing, and parts are of a one, not of a many [Plato] |
| Full Idea: The whole of which the parts are parts must be one thing composed of many; for each of the parts must be part, not of a many, but of a whole. | |
| From: Plato (Parmenides [c.364 BCE], 157c) | |
| A reaction: This is a key move of metaphysics, and we should hang on to it. The other way madness lies. |
| 13259 | It seems that the One must be composed of parts, which contradicts its being one [Plato] |
| Full Idea: The One must be composed of parts, both being a whole and having parts. So on both grounds the One would thus be many and not one. But it must be not many, but one. So if the One will be one, it will neither be a whole, nor have parts. | |
| From: Plato (Parmenides [c.364 BCE], 137c09), quoted by Kathrin Koslicki - The Structure of Objects 5.2 | |
| A reaction: This is the starting point for Plato's metaphysical discussion of objects. It seems to begin a line of thought which is completed by Aristotle, surmising that only an essential structure can bestow identity on a bunch of parts. |
| 18389 | When entities contain entities, or overlap with them, there is 'partial' identity [Armstrong] |
| Full Idea: There is 'partial identity' where one entity contains another with something to spare, or else where entities overlap each other. ...Extensive quantities, such as length and mass, are the particularly plausible cases. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 08.5) | |
| A reaction: This looks like a very useful concept which deserves wider use. It will help discussions of rivers, statues, intersecting roads etc. |
| 15847 | Two things relate either as same or different, or part of a whole, or the whole of the part [Plato] |
| Full Idea: Everything is surely related to everything as follows: either it is the same or different; or, if it is not the same or different, it would be related as part to whole or as whole to part. | |
| From: Plato (Parmenides [c.364 BCE], 146b) | |
| A reaction: This strikes me as a really helpful first step in trying to analyse the nature of identity. Two things are either two or (actually) one, or related mereologically. |
| 22505 | The two right angles of a triangle necessitate that a quadrilateral has four [Aristotle] |
| Full Idea: If it is necessary that, if a triangle contains two right angles, that a quadrilateral has four, it is clear that the cause of this is that a triangle has two. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1222b31) | |
| A reaction: We would not normally use the word 'cause' for this, but 'necessitates' seems to fit, and I like the word 'determines' (because it can be both physical and abstract). An example of what I think of as an Aristotelian necessity maker. |
| 18388 | Possible worlds don't fix necessities; intrinsic necessities imply the extension in worlds [Armstrong] |
| Full Idea: It seems natural and plausible to say that it is the fact that a necessary truth is itself necessary that determines its truth in all possible worlds. This intension determines its extension across possible worlds. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 08.1) | |
| A reaction: Well said. To me (but not to Armstrong) this implies essentialism, that the necessity arises from the intrinsic natures of the things involved. The whole Lewisian approach of explaining things by mapping them strikes me as wrong. |
| 22513 | Knowing is having knowledge; understanding is using knowledge [Aristotle] |
| Full Idea: Knowing and understanding is of two kinds, one having and the other using knowledge. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1225b11) | |
| A reaction: This corresponds to potential and actual. We wouldn't say that understanding must be used, but we have some sort of distinction between knowledge as pure and theoretical, and understanding enabling good application. |
| 23906 | Courage from spirit is natural and unconquerable, as seen in the young [Aristotle] |
| Full Idea: The courage of spirit is the most natural kind; for spirit is unconquerable, which is why the young are the best fighters. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1229a27) | |
| A reaction: [thumos, presumably, as in Plato] I suppose Aristotle knows better than me, but I suspect the young are just the quickest and strongest. I'd rather be led by someone with experience than by someone who is young. |
| 20204 | Whether the mind has parts is irrelevant, since it obviously has distinct capacities [Aristotle] |
| Full Idea: It makes no difference if the soul is divided into parts or lacks parts, as it certainly has distinct capacities. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1219b32), quoted by Linda Trinkaus Zagzebski - Virtues of the Mind II 3.1 | |
| A reaction: I take this to endorse my view that the mind-body problem is of limited interest to philosophers. The focus should be on what the mind does, not how it is constructed. But then I presume the latter issue is revealed by neuroscience. |
| 18375 | General truths are a type of negative truth, saying there are no more ravens than black ones [Armstrong] |
| Full Idea: General truths are a species of negative truth, 'no more' truths, asserting that there are no more men than the mortal ones, no more ravens than the black ones. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 05.1) | |
| A reaction: He goes on to distinguish between 'absences' and 'limits' in this area. |
| 22506 | A man is the cause of what is within his power, and what he causes is in his power [Aristotle] |
| Full Idea: All those things that are in man's power either to do or not to do he himself is the cause of, and all those things that he is the cause of are in his own power. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1223a08) | |
| A reaction: This is the step which allows us to abandon free will, and replace it with the question of whether a person is the 'cause' of an action. Aristotle carefully delineates the criteria for when an action is within a person's power. Includes failures to act? |
| 22504 | Only a human being can be a starting point for an action [Aristotle] |
| Full Idea: A human being is a starting point of some actions, and he alone of animals; for of nothing else should we say that it acted. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1222b19) | |
| A reaction: It is a standard dogma that the idea of free will does not occur in Plato or Aristotle, but this looks awfully like it. I don't agree about animals. You watch them judging whether they can make a leap, and then doing it. |
| 22510 | Some emotional states are too strong for human nature [Aristotle] |
| Full Idea: Many classify even love as involuntary, and certain cases of anger and certain natural states as being too strong for human nature; and we regard them as being pardonable, as being of such a nature as to be constrained by nature. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1225b20) | |
| A reaction: Blind terror would presumably count as another such state. An interesting aspect of Aristotle's picture - that human nature contains ingredients that are not part of a natural harmonious whole. |
| 23913 | Nearly all the good and bad states of character are concerned with feelings [Aristotle] |
| Full Idea: Pretty much all of the praiseworthy or blameworthy states concerned with character are either excesses, deficiencies, or medial conditions in feelings. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1233b16) | |
| A reaction: Suggests that the ideal state of character is the result of long and careful tuning of the feelings - insofar as we can control them. Presumably we can train feelings of hatred or compassion, by appropriate exposures. These states are NOT virtues. |
| 18368 | For all being, there is a potential proposition which expresses its existence and nature [Armstrong] |
| Full Idea: The thesis of 'expressibility' says that for all being, there is a proposition (perhaps one never formulated by any mind at any time) that truly renders the existence and nature of this being. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 02.3.2) | |
| A reaction: [He credits Stephen Read 2000:68-9 for this] Armstrong accepts this, but I deny it. I can't make any sense of this vast plethora of propositions, each exactly expressing some minute nuance of the infinity complexity of all being. |
| 18370 | A realm of abstract propositions is causally inert, so has no explanatory value [Armstrong] |
| Full Idea: We could not stand in any causal or nomic relation to a realm of propositions over and above the space-time world, ...so it is unclear that such a postulation is of any explanatory value. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 02.6) | |
| A reaction: I agree, and I like Armstrong's appeal to explanation as a criterion for whether we should make an ontological commitment here. I am baffled by anyone who thinks reality is crammed full of unarticulated propositions. Only a philosopher.... |
| 23918 | Akrasia is the clash of two feelings - goodness and pleasure [Aristotle] |
| Full Idea: The discord between the good and the pleasant in one's feelings is lack of self-control. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1237a08) | |
| A reaction: A nice clear statement of his view, which opposes the view of Socrates that akrasia is a failure of reason or judgement. Goodness seems to be treated here as a feeling, which is unusual. |
| 22515 | Choice results when deliberation brings together an opinion with an inclination [Aristotle] |
| Full Idea: Choice is neither simply wish nor opinion, but opinion together with inclination, whenever as a result of deliberation they are brought to a conclusion. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1227a04) | |
| A reaction: This seems to be the earliest appearance of the belief-plus-desire theory of action, which is often associated with Hume. A choice does not necessarily result from having the inclination and the appropriate opinion. Laziness! |
| 22508 | Unlike in inanimate things, in animate things actions have more than one starting point [Aristotle] |
| Full Idea: In inanimate things the starting-point is single, in animate things there is more than one; for inclination and reason are not always in harmony. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1224a24) | |
| A reaction: It is important that this seems to include non-human animals. We see animals avoid something which they desire, presumably because they detect a danger. They may be conflicting desires, but it is rational to prioritise dangers. |
| 22514 | The deliberative part of the soul discerns explanatory causes [Aristotle] |
| Full Idea: That part of the soul is deliberative which is capable of discerning a cause: the reason for the sake of which - which is one of the causes - 'cause' being something because-of-which. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1226b26) | |
| A reaction: I take because-of-which to be the correct explanation. Since my model of practical reasoning is partly forensic detection, this seems right. Sherlock Holmes spots causes. |
| 22507 | An action is voluntary when it is accompanied by thought of some kind [Aristotle] |
| Full Idea: The voluntary consists in action accompanied by thought of some kind. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1224a06) | |
| A reaction: This is thought as opposed to inclination or choice. The controlled person [enkrateia] voluntarily acts against inclinations. The appropriate thought receives carefull analysis in NE 1109b30-1111b4. |
| 23319 | We are responsible if our actions reflect our motivation [Aristotle, by Frede,M] |
| Full Idea: For Aristotle, for us to be responsible for what we do, our action has to somehow reflect our motivation. | |
| From: report of Aristotle (Eudemian Ethics [c.333 BCE], 1224a07) by Michael Frede - A Free Will 2 | |
| A reaction: This sounds like 'mens rea' in law - meaning to do the thing you did. But we can obviously be responsible for things through neglect, for example. |
| 22512 | Acts are voluntary if done knowingly, by the agent, and in his power to avoid it [Aristotle] |
| Full Idea: Whatever a man does - not in ignorance, and through his own agency - when it is in his power not to do it, must be voluntary, and that is what voluntary is. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1225b08) | |
| A reaction: This is the conclusion of the Eudemian discussion of responsibility. This is a definition by necessary and sufficient conditions. How can you be sure that something is in your power not to do? |
| 22509 | What is natural for us is either there at birth, or appears by normal processes [Aristotle] |
| Full Idea: By these marks we distinguish what comes naturally: everything that is there straightaway as soon as something comes to be, and all that occurs to us if growth is allowed to proceed normally - such as greying hair, ageing, and the like. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1224b32) | |
| A reaction: The word 'normal' has to do a lot of work here. Presumably jaundice in a neonate is not included. Or later hereditary diseases. |
| 18230 | No one would choose life just for activities not done for their own sake [Aristotle] |
| Full Idea: If we put together all the things that are ....not done or undergone for their own sake ...no one would choose, in order to have them, to be alive rather than not. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1215), quoted by Christine M. Korsgaard - Aristotle and Kant on the Source of Value 8 'Finality' | |
| A reaction: Debatable. Roughly his question is whether you would rather be dead than be a slave, since slaves work for means, but have no ends. Aristotle would rather die, but those who surrendered in ancient battles preferred slavery. |
| 23909 | Wearing a shoe is its intrinsic use, and selling it (as a shoe) is its coincidental use [Aristotle] |
| Full Idea: There is intrinsic use of a possession, such as of a shoe or a cloak, and its coincidental use - not of course when using a shoe as a weight, but as, for example, selling it or hiring it out (for then a shoe is used as a shoe). | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1231b37) | |
| A reaction: This seems to need a third label, for using the shoe as a weight. 'Inessential use' perhaps, since the intrinsic use points towards the essential nature or function of the shoe. |
| 5870 | Everything seeks, not a single good, but its own separate good [Aristotle] |
| Full Idea: It is not true that everything that there is seeks some single good: each thing has an inclination for its own good, the eye for sight, the body for health, and so on. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1218a30) | |
| A reaction: Aristotle's pluralism. Elsewhere this pluralism arises from his function argument - that the good of each thing is the successful fulfilment of its function, which is different for each thing. This is basic to virtue theory, and has my approval. |
| 5877 | We judge people from their deeds because we cannot see their choices (which matter more) [Aristotle] |
| Full Idea: It is because it is not easy to discern what sort of choice it is that we are forced to judge from the deeds what sort of person someone is; the activity is more worth having, but the choice is commended more. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1228a15) | |
| A reaction: This shows why Aristotle is the most important opponent of consequentialism. It is hard to see how one could praise a self-interested deed simply because it benefited others. Greed is never good. |
| 5868 | Horses, birds and fish are not happy, lacking a divine aspect to their natures [Aristotle] |
| Full Idea: No horse or bird or fish is happy, nor any other thing that there is which does not have a share by its nature in the divine. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1217a26) | |
| A reaction: Pet owners will all feel their beloved companions have been insulted, but I agree with this. 'Happy' does not here mean 'in a state of pleasure'. A fully successful bird does little more than the four f's (feed, fornicate, flee, fight). |
| 5865 | Happiness involves three things, of which the greatest is either wisdom, virtue, or pleasure [Aristotle] |
| Full Idea: To be happy, and to live the fine and divinely-happy life, would seem to reside in three things above all, ..for some say that wisdom is the greatest good, others virtue, others pleasure. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1214a30) | |
| A reaction: Aristotle is well-known for his pluralist answer to this question: virtue is crucial, wisdom is perhaps the greatest of the virtues, and pleasure improves everything in life. |
| 5876 | Virtue is different from continence [Aristotle] |
| Full Idea: Virtue is different from continence. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1227b17) | |
| A reaction: Basic to Aristotle - in that continence leads to right action, but that is not enough for virtue, which requires inner harmony, reason, and pleasure in doing what is right. Hence Aristotle is quite distinct from deontological or consequentialist views. |
| 5872 | Excellence is the best state of anything (like a cloak) which has an employment or function [Aristotle] |
| Full Idea: Excellence is the best disposition, state or capacity of anything that has some employment or function; this is evident from induction. For example, a cloak has an excellence - and a certain function and employment also; its best state is its excellence. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1219a02) | |
| A reaction: 'Employment' will be an assigned function, and 'function' will be a natural or intrinsic function, I presume. This is a nice clear illustration of the fact that for Aristotle virtue runs continuously from people to cloaks. See Idea 1663, though. |
| 5874 | Character virtues (such as courage) are of the non-rational part, which follows the rational part [Aristotle] |
| Full Idea: The virtues of character belong to the part that is non-rational, but whose nature is to follow the rational part; we do not say what a man's character is like when we say that he is wise or clever, but when we say that he is gentle or daring. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1220a11) | |
| A reaction: In the Nichomachean Ethics it appears that good character is the 'harmony' between the two parts; here it sounds more like obedience. It seems to me that our rational part is a failure if it is not sensitive to the needs of the irrational part. |
| 22516 | Character is shown by what is or is not enjoyed, and virtue chooses the mean among them [Aristotle] |
| Full Idea: Virtue is that state of character which chooses the mean, relative to us, in things pleasant and unpleasant, all those in respect of which a man is said to have a certain sort of character according as he enjoys or suffers pain from them. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1227b08) | |
| A reaction: The 'mean' should be understood as what is appropriate, rather than the mere average. Strong anger, for example, is sometimes appropriate. Does Aristotle rule out wild laughter, or frenetic dancing? Is a state of ecstasy wicked? |
| 22517 | We judge character not by their actions, but by their reasons for actions [Aristotle] |
| Full Idea: It is from his choosing that we judge what sort of person someone is; that is, what that for whose sake he does something is, not what he does. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1228a03) | |
| A reaction: Not entirely true. It can be sufficient to reveal their character that a person does some particular thing, as novelists know. When Hud parks his car in her flowerbed, we don't need to enquire about his reason. But see 1228a16! |
| 5875 | Character (éthos) is developed from habit (ethos) [Aristotle] |
| Full Idea: Character (éthos), as the word itself indicates, is developed from habit (ethos). | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1220a36) | |
| A reaction: Aristotle goes in for dubious etymologies, but this one sounds quite significant, and supports his view that habit is central to virtue. We would lose nothing in English if we said 'what are her habits?' instead of 'what is her character?'. |
| 23914 | People sometimes exhibit both extremes together, but the mean is contrary to both of them [Aristotle] |
| Full Idea: The mean is more contrary to the extremes than the extremes are to each other, because it does not occur with either of them, whereas the extremes often occur with each other. People can be rash cowards, or wasteful in some things and generous in others. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1234a33) | |
| A reaction: This rather undermines the neat visual metaphor of a sliding scale, but gives a more accurate account of the mean. The diagram needs three dimensions, instead of two. |
| 23911 | Possessors of a virtue tend to despise what reason shows to be its opposite [Aristotle] |
| Full Idea: Each virtue makes its possessor tend to despise great things that are contrary to reason - for example, courage does this of dangers, …a temperate person of many pleasures, and a generous one of many sorts of wealth. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1232a37) | |
| A reaction: I like the observation that the generous tend to despise wealth, implying that those who love wealth tend to lack generosity. Christianity has encouraged us to reject the idea of despising anything - but that seems to iron out common sense values. |
| 23910 | Greatness of soul produces all the virtues - and vice versa [Aristotle] |
| Full Idea: All the virtues will follow along with greatness of soul, or it will follow along with all of them | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1232a36) | |
| A reaction: This is obviously similar in some respects to Nietzsche's 'higher' man, though that suggests greater independence, rather than being an ideal citizen. |
| 23908 | If someone just looks at or listens to beautiful things, they would not be thought intemperate [Aristotle] |
| Full Idea: If someone looks at a beautiful statue, or horse, or human being, or listens to someone singing …just to look at or listen to beautiful things, he would not be thought to be intemperate, any more than those beguiled by the Sirens would. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1230b31) | |
| A reaction: He says that intemperance mainly concerns taste and touch, rather than mere looking or listening. I think obsessive collectors of beautiful objects might drift into intemperance. |
| 23905 | Courage follows reason, which tells us to choose what is noble [Aristotle] |
| Full Idea: Courage is a following of reason, and reason orders us to choose what is noble. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1229a01) | |
| A reaction: This sounds right to me. Courage, in all sorts of contexts, seems to arise in people who sustain their focus on what is the right thing to do. |
| 23912 | Honour depends on what it is for, and whether it is bestowed by worthy people [Aristotle] |
| Full Idea: It makes a difference whether the honour comes from many random people or from those worthy of note, and again so does by whom and for what the honor is conferred. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1232b18) | |
| A reaction: He tends to play down honour because of its relativism, but this quotation implies that if an honour was bestowed by the worthy, for something of agreed high value, then it would be at quite a different level from mere popular esteem. Celebrity v peerage? |
| 5871 | Goods in the soul are more worthy than those outside it, as everybody wants them [Aristotle] |
| Full Idea: All goods are either in the soul or outside it, and it is those in the soul that are more worthy of choice; for wisdom, virtue and pleasure are in the soul, and some or all of these seem to be an end for everyone. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1218b34) | |
| A reaction: An interesting reason for this assertion - that it is true because everybody agrees on it. See Idea 95. I would think that he might claim that our soul is our essence, whereas external goods pander to the non-essential in us. |
| 23920 | Decent people can be friends with base people [Aristotle] |
| Full Idea: It is possible for a decent person to be friends with a base one. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1238b01) | |
| A reaction: This is on the basis of being useful, or of having something in common. Presumably friendship can come in degrees, as well as being of different kinds. Even the finest people can differ a lot, and only have a limited friendship. |
| 23919 | Friendship cannot be immediate; it takes time, and needs testing [Aristotle] |
| Full Idea: Just as if people wish to be healthy they do not become healthy, so if they wish to be friends they are not immediately in fact friends. …[1237b40] For a friend is not to be had without a test or in a single day, but needs time. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1237b21) | |
| A reaction: The voice of experience, I think. Obviously trust is basic, and it would be unwise to trust a possible friend on the first day. Since politics aims at friendship, I presume the support of the rule of law helps to achieve trust. |
| 23915 | The main function of politics is to produce friendship [Aristotle] |
| Full Idea: It seems to be most of all the function of politics to produce friendship. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1245b22) | |
| A reaction: Lovely! Most people would probably cite wealth and security as the main aims. This function seems to require quite a high degree of equality, though Aristotle doesn't think it essential. |
| 23916 | The best cure for mutual injustice is friendship [Aristotle] |
| Full Idea: If one wishes to make it so that people do not commit injustices to each other, it is enough to make them friends; for true friends do not commit injustice. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1245b28) | |
| A reaction: This, along with Idea 23915, offers a beautiful vision of what a society should try to achieve. There can be duplicitous apparent friends, but on the whole the best way to cure unjust relations is friendship. Imagine Jews and Arabs being friends (2023). |
| 222 | Only a great person can understand the essence of things, and an even greater person can teach it [Plato] |
| Full Idea: Only a man of very great natural gifts will be able to understand that everything has a class and absolute essence, and an even more wonderful man can teach this. | |
| From: Plato (Parmenides [c.364 BCE], 135a) |
| 5866 | It is folly not to order one's life around some end [Aristotle] |
| Full Idea: Not to have ordered one's life in relation to some end is a mark of extreme folly. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1214b10) | |
| A reaction: A most interesting claim, not found in the Nichomachean Ethics. There the teleology is descriptive, but here it is prescriptive. It is tempting to rebel against Aristotle's injuncture. He was a driven workaholic. Why not float through life like gossamer? |
| 5878 | Eyes could be used for a natural purpose, or for unnatural seeing, or for a non-seeing activity [Aristotle] |
| Full Idea: One might wonder if it is possible to use each thing both for its natural purpose and otherwise - and that as itself or incidentally. E.g. twisting an eye so that one thing appears two, but also using an eye as something to sell or eat. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1246a26) | |
| A reaction: The important idea here is the core notion that there is a 'natural' purpose. Sceptics might say that all purposes derive from how a mind wishes to use something; otherwise there would be processes, but no 'functions' or 'purposes'. |
| 5873 | Each thing's function is its end [Aristotle] |
| Full Idea: Each thing's function is its end. | |
| From: Aristotle (Eudemian Ethics [c.333 BCE], 1219a08) | |
| A reaction: Function and end are not the same, but this confirms how closely related they are for Aristotle. Can an inanimate object have an end, without having any apparent function? Could I construct a set of cogwheels which each had a function, but no end? |
| 225 | The unlimited has no shape and is endless [Plato] |
| Full Idea: The unlimited partakes neither of the round nor of the straight, because it has no ends nor edges. | |
| From: Plato (Parmenides [c.364 BCE], 137e) |
| 233 | Some things do not partake of the One [Plato] |
| Full Idea: The others cannot partake of the one in any way; they can neither partake of it nor of the whole. | |
| From: Plato (Parmenides [c.364 BCE], 159d) | |
| A reaction: Compare Idea 231 |
| 2062 | The only movement possible for the One is in space or in alteration [Plato] |
| Full Idea: If the One moves it either moves spatially or it is altered, since these are the only motions. | |
| From: Plato (Parmenides [c.364 BCE], 138b) |
| 231 | Everything partakes of the One in some way [Plato] |
| Full Idea: The others are not altogether deprived of the one, for they partake of it in some way. | |
| From: Plato (Parmenides [c.364 BCE], 157c) | |
| A reaction: Compare Idea 233. |
| 18380 | Negative causations supervene on positive causations plus their laws? [Armstrong] |
| Full Idea: Is it not very plausible that negative causations supervene on the positive causations together with the laws that govern the positive causations? | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 05.2.3) | |
| A reaction: This obviously has a naturalistic appeal, since all causation can then be based on the actual world. |
| 18401 | The pure present moment is too brief to be experienced [Armstrong] |
| Full Idea: The metaphysical present will be a strict instant, or, if time is not infinitely divisible, the present will be a minimum granule of duration. But strict instants or minimal granules of duration, if these exist, cannot be experienced. | |
| From: David M. Armstrong (Truth and Truthmakers [2004], 11) | |
| A reaction: He points out that this is ironic, since Presentism lies on the basic experience of the present. |
| 234 | We couldn't discuss the non-existence of the One without knowledge of it [Plato] |
| Full Idea: There must be knowledge of the one, or else not even the meaning of the words 'if the one does not exist' would be known. | |
| From: Plato (Parmenides [c.364 BCE], 160d) |
