“The costliness of keeping friends does not lie in what one does for them, but in what one, out of consideration for them, refrains from doing.”

In great memories there lies the seed of growth.

The greatest victory is defeat.

The majority is never right. Never, I tell you! That’s one of these lies in society that no free and intelligent man can help rebelling against. Who are the people that make up the biggest proportion of the population — the intelligent ones or the fools?

All the truth in the world adds up to one big lie.

One sometimes finds what one is not looking for. When I woke up just after dawn on Sept. 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer. But I guess that was exactly what I did.

I have a hundred times wished that one could resign life as an officer resigns a commission.
