A quote from Thomas Jefferson

For thus I estimate the qualities of the mind: 1, good humor; 2, integrity; 3, industry; 4, science. The preference of the first to the second quality may not at first be acquiesced in; but certainly we had all rather associate with a good-humored, light-principled man, than with an ill-tempered rigorist in morality.

— Letter to Dr. Benjamin Rush [January 3rd, 1808]
