Samuel Johnson on knowledge

The true measure of a man is how he treats someone who can do him absolutely no good.

Sex: the expense is damnable, the position is ridiculous, and the pleasure fleeting.

A second marriage is the triumph of hope over experience.

One thing only I know, and that is that I know nothing.

Socrates470–399 BC

Information is not knowledge.

There is only one good, knowledge, and one evil, ignorance.

Socrates470–399 BCII: xxxi. Original Greek: ἓν μόνον ἀγαθὸν εἶναι, τὴν ἐπιστήμην, καὶ ἓν μόνον κακόν, τὴν ἀμαθίαν

• Good & Evil
