Samuel Johnson on genius

The true measure of a man is how he treats someone who can do him absolutely no good.

Sex: the expense is damnable, the position is ridiculous, and the pleasure fleeting.

A second marriage is the triumph of hope over experience.

Not great understanding alone, not intelligence alone, nor both together, make genius. Love! Love! Love! that is the soul of genius.

Genius without education is like silver in the mine.

Benjamin Franklin1706–1790Poor Richard’s Almanack

• Education

Genius is one per cent inspiration, ninety-nine per cent perspiration.

Thomas Edison1847–1931
