Plato quotes - page 14
The attempt to separate everything from everything else is not only not in good taste but also shows that a man is utterly uncultivated and unphilosophical. The complete separation of each thing from all is the utterly final obliteration of all discourse. For our power of discourse is derived from the interweaving of the classes or ideas with one another.
Plato
The characters of self-restrained officials are exceedingly careful and just and conservative, but they lack keenness and a certain quick and active boldness. The courageous natures, on the other hand, are deficient in justice and caution in comparison with the former, but excel in boldness of action; and unless both these qualities are present it is impossible for a state to be entirely prosperous in public and private matters.
Plato
Socrates: I think the most likely view is, that these ideas exist in nature as patterns, and the other things resemble them and are imitations of them; their participation in ideas is assimilation to them, that and nothing else.
Parmenides: It is impossible that anything be like the idea, or the idea like anything; for if they are alike, some further idea, in addition to the first, will always appear, and if that is like anything, still another, and a new idea will always be arising, if the idea is like that which partakes of it.
Plato
Parmenides: Whatever the subject of your hypothesis, if you suppose that it is or is not, or that it experiences any other affection, you must consider what happens to it and to any other particular things you may choose, and to a greater number and to all in the same way; and you must consider other things in relation to themselves and to anything else you may choose in any instance, whether you suppose that the subject of your hypothesis exists or does not exist, if you are to train yourself completely to see the truth perfectly.
