A primary element has only a name, and no logos, but complexes have an account, by weaving the names [Plato]

The one was and is and will be and was becoming and is becoming and will become [Plato]

8. Modes of Existence / D. Universals / 6. Platonic Forms / a. Platonic Forms
Greatness and smallness must exist, to be opposed to one another, and come into being in things [Plato]

If absolute ideas existed in us, they would cease to be absolute [Plato]
Plato moves from Forms to a theory of genera and principles in his later work [Plato, by Frede,M]

The whole idea of each Form must be found in each thing which participates in it [Plato]
If things are made alike by participating in something, that thing will be the absolute idea [Plato]
If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato]
Participation is not by means of similarity, so we are looking for some other method of participation [Plato]
Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once [Plato]

If absolute greatness and great things are seen as the same, another thing appears which makes them seem great [Plato]
Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato]
9. Objects / B. Unity of Objects / 1. Unifying an Object / b. Unifying aggregates
Parts must belong to a created thing with a distinct form [Plato]

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]

Anything which has parts must be one thing, and parts are of a one, not of a many [Plato]
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
