At 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.
PlatoIf one sins against the laws of proportion and gives something too big to something too small to carry it - too big sails to too small a ship, too big meals to too small a body, too big powers to too small a soul - the result is bound to be a complete upset. In an outburst of hubris the overfed body will rush into sickness, while the jack-in-office will rush into the unrighteousness that hubris always breeds.
Plato
