| 14046 | A 'body' is a conception of an aggregate, with properties defined by application conditions [Epicurus] |
| Full Idea: Properties are known by their peculiar forms of application and comprehension, in close accompaniment with the aggregate [of atoms], which is given the predicate 'body' by reference to the aggregate conception. | |
| From: Epicurus (Letter to Herodotus [c.293 BCE], 69) | |
| A reaction: There is an interesting hint here of how to think of properties (as both applying and comprehended in some distinctive way), and a suggestion that there is something conventional about bodies, depending on how we conceive them. |
| 2084 | If a word has no parts and has a single identity, it turns out to be the same kind of thing as a letter [Plato] |
| Full Idea: If a complex or a syllable has no parts and is a single identity, hasn't it turned out to be the same kind of thing as an element or letter? | |
| From: Plato (Theaetetus [c.368 BCE], 205d) |
| 15844 | A sum is that from which nothing is lacking, which is a whole [Plato] |
| Full Idea: But this sum now - isn't it just when there is nothing lacking that it is a sum? Yes, necessarily. And won't this very same thing - that from which nothing is lacking - be a whole? | |
| From: Plato (Theaetetus [c.368 BCE], 205a) | |
| A reaction: This seems to be right, be rather too vague and potentially circular to be of much use. What is the criterion for deciding that nothing is lacking? |
| 15843 | The whole can't be the parts, because it would be all of the parts, which is the whole [Plato] |
| Full Idea: The whole does not consist of parts; for it did, it would be all the parts and so would be the sum. | |
| From: Plato (Theaetetus [c.368 BCE], 204e) | |
| A reaction: That is, 'the whole is the sum of its parts' is a tautology! The claim that 'the whole is more than the sum of its parts' gets into similar trouble. See Verity Harte on this. |
| 14047 | Bodies have impermanent properties, and permanent ones which define its conceived nature [Epicurus] |
| Full Idea: Impermanent properties do not have the nature of an entire thing, which we call a body when we grasp it in aggregate, nor the nature of permanent accompaniments without which it is not possible to conceive of a body. | |
| From: Epicurus (Letter to Herodotus [c.293 BCE], 70) | |
| A reaction: Epicurus doesn't discuss essences, but this seems to commit to the basic Aristotelian idea, that there there are some properties which actually bestow identity, and then others which are optional for that thing. The 'conception' is always mentioned. |
