Love is of something, and that which love desires is not that which love is or has; for no man desires that which he is or has. And love is of the beautiful, and therefore has not the beautiful. And the beautiful is the good, and therefore, in wanting and desiring the beautiful, love also wants and desires the good.
PlatoAt the Egyptian city of Naucratis there was a famous old god whose name was Theuth; the bird which is called the Ibis was sacred to him, and he was the inventor of many arts, such as arithmetic and calculation and geometry and astronomy and draughts and dice, but his great discovery was the use of letters.
