John F. Kennedy on knowledge

Ask not what your country can do for you⁠—ask what you can do for your country.

Leadership and learning are indispensable to each other.

For in the final analysis, our most basic common link, is that we all inhabit this small planet, we all breathe the same air, we all cherish our children’s futures, and we are all mortal.

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
