Benjamin Franklin on genius

A penny saved is a penny earned.

For the want of a nail, the shoe was lost; for the want of a shoe the horse was lost; and for the want of a horse the rider was lost, being overtaken and slain by the enemy, all for the want of care about a horseshoe nail.

They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.

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

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

Thomas Edison1847–1931

No great genius has ever existed without some touch of madness.

Aristotle384–322 BC
