Ralph Waldo Emerson on knowledge

It is one of the blessings of old friends that you can afford to be stupid with them.

The only way to have a friend is to be one.

What you do speaks so loudly that I cannot hear what you say.

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
