Plato

No evil can happen to a good man, either in life or after death.

Ignorance, the root and stem of all evil.

Never discourage anyone...who continually makes progress, no matter how slow.

Opinion is the medium between knowledge and ignorance.

The direction in which education starts a man will determine his future in life.

There are three classes of men: lovers of wisdom, lovers of honor, and lovers of gain.

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

No one is more hated than he who speaks the truth.

The greatest penalty of evildoing is to grow into the likeness of bad men.

Only the dead have seen the end of war.

The price good men pay for indifference to public affairs is to be ruled by evil men.

He who commits injustice is ever made more wretched than he who suffers it.

The worst of all deceptions is self-deception.

The beginning is the most important part of the work.

Music is a moral law. It gives soul to the universe, wings to the mind, flight to the imagination, and charm and gaiety to life and to everything.

I'm trying to think, don't confuse me with facts.

Justice in the life and conduct of the State is possible only as first it resides in the hearts and souls of the citizens.

We are twice armed if we fight with faith.

Good people do not need laws to tell them to act responsibly, while bad people will find a way around the laws.

Man is a being in search of meaning.
