There is no safety for honest men, but by believing all possible evil of evil men, and by acting with promptitude, decision, and steadiness on that belief.

An honest man is always a child.

Honesty is the cornerstone of character. The honest man or woman seeks not merely to avoid criminal or illegal acts, but to be scrupulously fair, upright, fearless in both action and expression. Honesty pays dividends both in dollars and in peace of mind.

It is almost impossible to be a doctor and an honest man, but it is obscenely impossible to be a psychiatrist without at the same time bearing the stamp of the most incontestable madness: that of being unable to resist that old atavistic reflex of the mass of humanity, which makes any man of science who is absorbed by this mass a kind of natural and inborn enemy of all genius.

And whether you’re an honest man, or whether you’re a thief, depends on whose solicitor has given me my brief.

Every honest man lives for himself. Every man worth calling a man lives for himself. The one who doesn’t – doesn’t live at all.
