Wit is educated insolence.

Wit is cultured insolence.

Humor is the only test of gravity, and gravity of humor; for a subject which will not bear raillery is suspicious, and a jest which will not bear serious examination is false wit.

The educated differ from the uneducated as much as the living from the dead.

Educated men are as much superior to uneducated men as the living are to the dead.

It is the mark of an educated mind to be able to entertain a thought without accepting it.
