Well, my book is written-let it go. But if it were only to write over again there wouldn't be so many things left out. They burn in me; and they keep multiplying; but now they can't ever be said. And besides, they would require a library-and a pen warmed up in hell.
In the space of one hundred and seventy-six years the Mississippi has shortened itself two hundred and forty-two miles. Therefore, in the Old Silurian Period the Mississippi River was upward of one million three hundred thousand miles long, seven hundred and forty-two years from now the Mississippi will be only a mile and three-quarters long. There is something fascinating about science. One gets such wholesome returns of conjecture out of such a trifling investment of fact.
Thanksgiving Day - Let all give humble, hearty, and sincere thanks, now, but the turkeys. In the island of Fiji they do not use turkeys, they use plumbers. It does not become you and me to sneer at Fiji.
If it's your job to eat a frog, it's best to do it first thing in the morning. And If it's your job to eat two frogs, it's best to eat the biggest one first.
Our Bible reveals to us the character of our god with minute and remorseless exactness... It is perhaps the most damnatory biography that exists in print anywhere. It makes Nero an angel of light and leading by contrast.
We could use up two Eternities in learning all that is to be learned about our own world and the thousands of nations that have arisen and flourished and vanished from it. Mathematics alone would occupy me eight million years.
There is no such thing as a new idea. It is impossible. We simply take a lot of old ideas and put them into a sort of mental kaleidoscope. We give them a turn and they make new and curious combinations. We keep on turning and making new combinations indefinitely; but they are the same old pieces of colored glass that have been in use through all the ages.
Man is the only animal that deals in that atrocity of atrocities War. He is the only one that gathers his brethren about him and goes forth in cold blood and calm pulse to exterminate his kind. He is the only animal that for sordid wages will march out... and help to slaughter strangers of his own species who have done him no harm and with whom he has no quarrel.... And in the intervals between campaigns he washes the blood off his hands and works for the universal brotherhood of man with his mouth.
Even the clearest and most perfect circumstantial evidence is likely to be at fault, after all, and therefore ought to be received with great caution. Take the case of any pencil, sharpened by any woman; if you have witnesses, you will find she did it with a knife; but if you take simply the aspect of the pencil, you will say that she did it with her teeth.
Never put off until tomorrow what you can avoid altogether. A clean desk is a sign of a cluttered desk drawer. All you need in this life is ignorance and confidence, and then success is sure.
