Marcus Aurelius on knowledge

In the life of a man, his time is but a moment…his sense, a dim rushlight. All that is body is as coursing waters…all that is of the soul, as dreams, and vapors.

I have often wondered how it is that every man loves himself more than all the rest of men, but yet sets less value on his own opinion of himself than on the opinion of others.

It is not death that a man should fear, but he should fear never beginning to live.

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
