Progress is the mother of all problems.

There are many ways to fall down, but there's only one way to stand up straight.

Who would condescend to strike down the mere things that he does not fear? Who would debase himself to be merely brave, like any common prizefighter? Who would stoop to be fearless--like a tree? Fight the thing that you fear. You remember the old tale of the English clergyman who gave the last rites to the brigand of Sicily, and how on his death-bed the great robber said, 'I can give you no money, but I can give you advice for a lifetime: your thumb on the blade, and strike upwards.' So I say to you, strike upwards, if you strike at the stars.

You have not wasted your time; you have helped to save the world. We are not buffoons, but very desperate men at war with a vast conspiracy.

One sees great things from the valley; only small things from the peak.

There is only one reason an intelligent person doesn't believe in miracles. He or she believes in materialism.

People seem to fight about things very unsuitable for fighting. They make a frightful noise in support of very quiet things. They knock each other about in the name of very fragile things.
