Plato

"The measure of a man is what he does with power."

"Wise men speak because they have something to say; fools because they have to say something."

"We can easily forgive a child who is afraid of the dark; the real tragedy of life is when men are afraid of the light."

"One of the penalties for refusing to participate in politics is that you end up being governed by your inferiors."

"The beginning is the most important part of the work."
