I love to revel in philosophical matters-especially astronomy. I study astronomy more than any other foolishness there is. I am a perfect slave to it. I am at it all the time. I have got more smoked glass than clothes. I am as familiar with the stars as the comets are. I know all the facts and figures and have all the knowledge there is concerning them. I yelp astronomy like a sun-dog, and paw the constellations like Ursa Major.

When we remember we are all mad, the mysteries disappear and life stands explained.

Nations do not think, they only feel. They get their feelings at second hand through their temperaments, not their brains. A nation can be brought -- by force of circumstances, not argument -- to reconcile itself to any kind of government or religion that can be devised; in time it will fit itself to the required conditions; later it will prefer them and will fiercely fight for them.

We are strange beings, we seem to go free, but we go in chains - chains of training, custom, convention, association, environment - in a word, Circumstance, and against these bonds the strongest of us struggle in vain.

When I was fourteen, my father was so ignorant I could hardly stand to have him around. When I got to be twenty-one, I was astonished at how much he had learned in seven years. See what happens when you "know it all", at any stage of life? Farther down the track you may see clearly how certain personal opinions, held onto too tightly, could be fogging up the view, and providing incorrect insight. Prosperity is the best protector of principle.

It is noble to teach oneself; it is still nobler to teach others.
