Whose interest was it? To whose prejudice was it? [Who might expect to derive benefit, or injury, from a crime committed?]

It is folly for an eminent man to think of escaping censure, and a weakness to be affected with it. All the illustrious persons of antiquity, and indeed of every age in the world, have passed through this fiery persecution.

It is not by the gray of the hair that one knows the age of the heart.

Why do people talk of the horrors of old age? It's great. I feel like a fine old car with the parts gradually wearing out, but I'm not complaining,... Those who find growing old terrible are people who haven't done what they wanted with their lives.

No man was ever so completely skilled in the conduct of life, as not to receive new information from age and experience.
