William Shakespeare on knowledge

If music be the food of love, play on.

This above all: to thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man.

Cowards die many times before their deaths. The valiant never taste of death but once.

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
