Voltaire | men can be influenced by making them think for themselves

"Controversy never convinced any man; men can be influenced by making them think for themselves, by seeming to doubt with them, by leading them as if by the hand, without their perceiving it. A good book lent to them, which they read at leisure, produces upon them surer effects, because they do not then blush to be subjugated by the superior reason of an antagonist."

Voltaire

Voltaire | our hope our illusion

"One day everything will be well, that is our hope. Everything's fine today, that is our illusion"

Voltaire

Voltaire | can make you believe absurdities

"Those who can make you believe absurdities, can make you commit atrocities"

Voltaire
