“Opinion is a fitting thing but truth outlasts the sun - if then we cannot own them both, possess the oldest one.”

“He saw that no one owned anything really. It's all rented, or borrowed. Our possessions will outlast us, we'll desert them in the end.”

“We must love them both, those whose opinions we share and those whose opinions we reject, for both have labored in the search for truth, and both have helped us in finding it.”

“All that is great cannot be possessed - and that is one of the most foolish things man goes on doing. We want to possess.”

“The modern habit of saying "This is my opinion, but I may be wrong" is entirely irrational. If I say that it may be wrong, I say that is not my opinion. The modern habit of saying "Every man has a different philosophy; this is my philosophy and it suits me" – the habit of saying this is mere weak-mindedness. A cosmic philosophy is not constructed to fit a man; a cosmic philosophy is constructed to fit a cosmos. A man can no more possess a private religion than he can possess a private sun and moon.”

“Opinions cannot survive if one has no chance to fight for them.”
