William Blake on good and evil

If the doors of perception were cleansed every thing would appear to man as it is, infinite. For man has closed himself up, till he sees all things thru’ narrow chinks of his cavern.

I was angry with my friend I told my wrath, my wrath did end. I was angry with my foe: I told it not, my wrath did grow.

What is now proved was once only imagined.

All that is required for evil to prevail is for good men to do nothing.

Edmund Burke1729–1797

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

Blaise Pascal1623–1662

• Anti-Religion

The world is a dangerous place, not because of those who do evil, but because of those who look on and do nothing.

Albert Einstein1879–1955
