Dictionary of 185 terms
a fragment of the definitions of the Academy
developing definitions was a common intellectual practice in ancient Greece
correct definitions were thought to make people morally better
There is no writing of Plato’s, nor will there ever be. Those that are now called so come from an idealized and youthful Socrates. (II)
Strength, courage, and cleverness are qualities in which others also may win distinction; but to be preeminent above others in truthfulness, justice, high-mindedness, and the grace of conduct—this is what would by general consent be expected of those who profess to honor these traits of character. (IV)
Don’t forget that one must please men if one would do anything with them, whereas self-will is fit only for solitude. (IV)
None of us can avoid death, nor if any man could would he be happy, as people think. (VII)
For every real being, there are three things that are necessary if knowledge of it is to be acquired: first, the name; second, the definition; third, the image; knowledge comes fourth, and in the fifth place we must put the object itself, the knowable and truly real being. (VII)
QUOTES FROM LETTERS
(1) You gaze at the stars, my Star; would that I were Heaven, that I might look at you with many eyes!
(2) Even as you shone once the Star of Morning, among the living, so in death you shine now the Star of Evening among the dead.
(6) When I kiss Agathon, my soul is on my lips, where it comes, poor thing, hoping to cross over.
(7) I throw the apple at you, and if you are willing to love me, take it and share your girlhood with me..
(8) I am an apple, one who loves you throws me at you. Say yes, Xanthippe; we fade, both you and I.
