The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it.

There is only one good, knowledge, and one evil, ignorance.

There is no reason why good cannot triumph as often as evil. The triumph of anything is a matter of organization. If there are such things as angels, I hope that they are organized along the lines of the Mafia.

I object to violence because when it appears to do good, the good is only temporary; the evil it does is permanent.

"There are plenty of good reasons for fighting," I said, "but no good reason ever to hate without reservation, to imagine that God Almighty Himself hates with you, too. Where's evil? It's that large part of every man that wants to hate without limit, that wants to hate with God on its side."

Men never do evil so completely and cheerfully as when they do it from religious conviction.

What is done out of love always takes place beyond good and evil.

False words are not only evil in themselves, but they infect the soul with evil.

Ignorance, the root and the stem of every evil.

It is easier to contend with evil at the first than at the last.

"Monsters are real, and ghosts are real too. They live inside us, and sometimes, they win.

An evil life is a kind of death.

Until philosophers are kings, or the kings and princes of this world have the spirit and power of philosophy, and political greatness and wisdom meet in one, and those commoner natures who pursue either to the exclusion of the other are compelled to stand aside, cities will never have rest from their evils - no, nor the human race, as I believe - and then only will this our State have a possibility of life and behold the light of day.

The evil that is in the world always comes of ignorance, and good intentions may do as much harm as malevolence, if they lack understanding. On the whole men are more good than bad; that, however, isn't the real point. But they are more or less ignorant, and it is this that we call vice or virtue; the most incorrigible vice being that of an ignorance which fancies it knows everything and therefore claims for itself the right to kill. There can be no true goodness, nor true love, without the utmost clear-sightedness.

You cannot have power for good without having power for evil too. Even mother's milk nourishes murderers as well as heroes.
