Quote of the Week

If anyone can refute me–show me I'm making a mistake or looking at things from the wrong perspective–I'll gladly change. It's the truth I'm after, and the truth never harmed anyone. What harms us is to persist in self-deceit and ignorance.

Marcus Aurelius, Roman emperor

Skeptical Quote of the Week (1:39:01)

If anyone can refute me–show me I'm making a mistake or looking at things from the wrong perspective–I'll gladly change. It's the truth I'm after, and the truth never harmed anyone. What harms us is to persist in self-deceit and ignorance.
– Marcus Aurelius (121-180), Roman emperor and Stoic philosopher, from Meditations Book 6, Number 21
