Euripides on good and evil

There is one thing alone that stands the brunt of life throughout its course: a quiet conscience.

‘Twas but my tongue, ‘twas not my soul that swore.

This is slavery, not to speak one’s thought.

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
