In all men is evil sleeping; the good man is he who will not awaken it, in himself or in other men..

Mary Renault, The Praise Singer

I couldn’t claim that I have never felt the urge to explore evil, but when you descend into hell, you have to be very careful.

Kathleen Raine

What is a good man but a bad man’s teacher? / What is a bad man but a good man’s job? / If you don’t understand this, you will get lost, / however intelligent you are.

Laozi

If . . . you can’t be a good example, then you’ll just have to be a horrible warning.

Catherine Aird, His Burial Too

Good and evil, as we term them, are not antagonistic; they are ever found hand in hand. Humanity has never achieved a single conquest without the aid of both. Indeed how can she? What adds to moral strength, but a grappling with temptation?

Sarah Grimké

I’m on the thin side of evil and trying not to break through.

Toni Morrison, Song of Solomon

What makes some people more virtuous than others? Is it something they know from birth? Don’t they ever feel that zingy, thrilling urge to smash the world to bits? Isn’t it possible, maybe, that good people are just luckier people?

Anne Tyler, A Patchwork Planet

There are times when it would seem as if God fished with a line, and the devil with a net.

Anne-Sophie Swetchine

It is the modest nature of goodness to exert itself quietly, while a few characters of the opposite cast seem, by the rumor of their exploits, to fill the world; and by their noise to multiply their numbers.

Hannah More

As for an authentic villain, the real thing, the absolute, the artist, one rarely meets him even once in a lifetime. The ordinary bad hat is always in part a decent fellow.

Colette, Break of Day

Imaginary evil is romantic and varied; real evil is gloomy, monotonous, barren, boring. Imaginary good is boring; real good is always new, marvelous, intoxicating.

Simone Weil

What would your good do if evil didn’t exist, and what would the earth look like if all the shadows disappeared? After all, shadows are cast by things and people. Here is the shadow of my sword. But shadows also come from trees and living beings. Do you want to strip the earth of all trees and living things just because of your fantasy of enjoying naked light?

Mikhail Bulgakov, The Master and Margarita

There is no explanation for evil. It must be looked upon as a necessary part of the order of the universe. To ignore it is childish; to bewail it, senseless.

W. Somerset Maugham

Evil turned out not to be a grand thing. Not sneering emperors with world-conquering designs. Not cackling demons plotting in the darkness beyond the world. It was small men with their small acts and their small reasons. It was selfishness and carelessness and waste. It was bad luck, incompetence, and stupidity. It was violence divorced from conscience or consequence. It was high ideals, even, and low methods.

Joe Abercrombie, Red Country

No evil dooms us hopelessly except the evil we love, and desire to continue in, and make no effort to escape from.

George Eliot, Daniel Deronda

Human history is not the battle of good struggling to overcome evil. It is a battle fought by a great evil struggling to crush a small kernel of human kindness. But if what is human in human beings has not been destroyed even now, then evil will never conquer.

Vasily Grossman, Life and Fate

It is very hard for evil to take hold of the unconsenting soul.

Ursula K. Le Guin, A Wizard of Earthsea

There are depths in man that go the length of lowest Hell, as there are heights that reach highest Heaven—for are not both Heaven and Hell made out of him, made by him, everlasting Miracle and Mystery as he is?

Thomas Carlyle
