The principle of asceticism never was, nor ever can be, consistently pursued by any living creature. Let but one tenth part of the inhabitants of the earth pursue it consistently, and in a day’s time they will have turned it into a Hell.

Jeremy Bentham

Man is the cruelest animal. At tragedies, bullfights, and crucifixions he has so far felt best on earth; and when he invented hell for himself, behold, that was his very heaven.

Friedrich Nietzsche

The tree that would grow to heaven must send its roots to hell.

Friedrich Nietzsche

Work like hell! I had 122 rejection slips before I sold a story.

F. Scott Fitzgerald

Fear is death, fear is sin, fear is hell, fear is unrighteousness, and fear is wrong life. All the negative thoughts and ideas that are in the world have proceeded from this evil spirit of fear.

Swami Vivekananda

Nuclear power is one hell of a way to boil water.

Albert Einstein

There is no greater hell than to be a prisoner of fear.

Ben Jonson

I don't like to commit myself about heaven and hell you see, I have friends in both places.

Mark Twain

I am afraid that the schools will prove the very gates of hell, unless they diligently labor in explaining the Holy Scriptures and engraving them in the heart of the youth.

Martin Luther

The mind is its own place, and in itself can make a Heaven of Hell, a Hell of Heaven.

John Milton
