George Santayana on knowledge

Those who cannot remember the past are condemned to repeat it.

Trust the man who hesitates in his speech and is quick and steady in action, but beware of long arguments and long beards.

Fanaticism consists of redoubling your efforts when you have forgotten your aim.

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
