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.
It is impossible that a genius - at least a literary genius - can ever be discovered by his intimates; they are so close to him that he is out of focus to them and they can't get at his proportions; they can't perceive that there is any considerable difference between his bulk and their own.
There is no such thing as material covetousness. All covetousness is spiritual. ...Any so-called material thing that you want is merely a symbol: you want it not for itself, but because it will content your spirit for the moment.
There is only one expert who is qualified to examine the souls and the life of a people and make a valuable report - the native novelist. ... And when a thousand able novels have been written, there you have the soul of the people; and not anywhere else can these be had.
When even the brightest mind in our world has been trained up from childhood in a superstition of any kind, it will never be possible for that mind, in its maturity, to examine sincerely, dispassionately, and conscientiously any evidence or any circumstance which shall seem to cast a doubt upon the validity of that superstition. I doubt if I could do it myself.
Courage is resistance to fear, mastery of fear-not absence of fear. Except a creature be part coward it is not a compliment to say it is brave; it is merely a loose application of the word. Consider the flea! - incomparably the bravest of all the creatures of God, if ignorance of fear were courage.
Life was a fairy-tale, then, it is a tragedy now. When I was 43 and John Hay 41 he said life was a tragedy after 40, and I disputed it. Three years ago he asked me to testify again: I counted my graves, and there was nothing for me to say. I am old; I recognize it but I don't realize it. I wonder if a person ever really ceases to feel young - I mean, for a whole day at a time.
We can secure other people's approval, if we do right and try hard; but our own is worth a hundred of it, and no way has been found out of securing that.
There's nobody for me to attack in this matter even with soft and gentle ridicule-and I shouldn't ever think of using a grown up weapon in this kind of a nursery. Above all, I couldn't venture to attack the clergymen whom you mention, for I have their habits and live in the same glass house which they are occupying. I am always reading immoral books on the sly, and then selfishly trying to prevent other people from having the same wicked good time.
