It was on the 10th day of May - 1884 - that I confessed to age by mounting spectacles for the first time, and in the same hour I renewed my youth, to outward appearance, by mounting a bicycle for the first time. The spectacles stayed on.
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.
I have never taken any exercise, except sleeping and resting, and I never intend to take any. Exercise is loathsome. And it cannot be any benefit when you are tired; and I was always tired.
...we all know that in all matters of mere opinion that [every] man is insane-just as insane as we are...we know exactly where to put our finger upon his insanity: it is where his opinion differs from ours....All Democrats are insane, but not one of them knows it. None but the Republicans. All the Republicans are insane, but only the Democrats can perceive it. The rule is perfect: in all matters of opinion our adversaries are insane.
If a person offends you, and you are in doubt as to whether it was intentional or not, do not resort to extreme measures; simply watch your chance, and hit him with a brick.

Let your secret sympathies and your compassion be always with the under dog in the fight -- this is magnanimity; but bet on the other one -- this is business.
To be human is to have one's little modicum of romance secreted away in one's composition. One never ceases to make a hero of one's self, (in private,) during life, but only alters the style of heroism from time to time as the drifting years belittle certain gods of his admiration and raise up others in their stead.
