Richard Feynman on knowledge

Physics is like sex: sure, it may give some practical results, but that’s not why we do it.

To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature. If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.

All theoretical chemistry is really physics; and all theoretical chemists know it.

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
