6 ideas
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)
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)
If asked whether justice itself is just or unjust, you would have to say that it is just [Plato]
     Full Idea: If someone asked me 'Is justice itself just or unjust?' I should answer that it was just, wouldn't you? I agree.
     From: Plato (Protagoras [c.380 BCE], 330c)
If gods are like men, they are just eternal men; similarly, Forms must differ from particulars [Aristotle on Plato]
     Full Idea: We say there is the form of man, horse and health, but nothing else, making the same mistake as those who say that there are gods but that they are in the form of men. They just posit eternal men, and here we are not positing forms but eternal sensibles.
     From: comment on Plato (works [c.375 BCE]) by Aristotle - Metaphysics 997b
Forms have to be their own paradigms, which seems to fuse the paradigm and the copy [Aristotle]
     Full Idea: The Forms would have to function as paradigms not just for other entities, but also for themselves. ..But this produces an absurd fusion of the paradigm and the copy.
     From: Aristotle (Metaphysics [c.324 BCE], 1079b28)
     A reaction: A nice succinct statement of the problem of self-predication (which leads to the Third Man regress, if we posit another Form as a paradigm of the Form we are interested in).
Most thinkers now reject self-predication (whiteness is NOT white) so there is no Third Man problem [Armstrong]
     Full Idea: Modern upholders of universals generally reject self-predication; humanity is not a man, whiteness is not a white thing. This means that the Third Man argument does not constitute a difficulty.
     From: David M. Armstrong (Universals and Particulars [1995], p.506)
     A reaction: This certainly seems right, and is relevant to the modern problem of the content of thought. The idea of a tree does not need to be tree-like.
