Doctor Who and the Crusaders

Frankly, I never rely on luck. A most dangerous occupation. No, my boy, I believe in positive thought. I believe in optimism, provided one never takes it to ridiculous lengths. But above all, Chesterton, I’m convinced in the strength of logic and reasoned action. Impulse is all right in a fight, when the odds are against you and only some brilliant piece of improvisation can turn defeat into victory.

Force me to it, and I’ll turn the whole world into your enemy.
(Joanna to Richard)
