"Now what I contend is that my body is my own, at least I have always so regarded it. If I do harm through my experimenting with it, it is I who suffer, not the state."

"The Blessings-of-Civilization Trust, wisely and cautiously administered, is a Daisy. There is more money in it, more territory, more sovereignty, and other kinds of emolument, than there is in any other game that is played. But Christendom has been playing it badly of late years, and must certainly suffer by it, in my opinion. She has been so eager to get every stake that appeared on the green cloth, that the People who Sit in Darkness have noticed it -- they have noticed it, and have begun to show alarm. They have become suspicious of the Blessings of Civilization."

"Always do right. This will gratify some people, and astonish the rest."

"To create man was a fine and original idea; but to add the sheep was a tautology."

"Oh, dear me, how unspeakably funny and owlishly idiotic and grotesque was that "plagiarism" farce! As if there was much of anything in any human utterance, oral or written, except plagiarism! The kernel, the soul — let us go further and say the substance, the bulk, the actual and valuable material of all human utterances — is plagiarism. For substantially all ideas are second-hand, consciously and unconsciously drawn from a million outside sources, and daily used by the garnerer with a pride and satisfaction born of the superstition that he originated them; whereas there is not a rag of originality about them anywhere except the little discoloration they get from his mental and moral calibre and his temperament, and which is revealed in characteristics of phrasing. When a great orator makes a great speech you are listening to ten centuries and ten thousand men — but we call it his speech, and really some exceedingly small portion of it is his. But not enough to signify. It is merely a Waterloo. It is Wellington's battle, in some degree, and we call it his; but there are others that contributed. It takes a thousand men to invent a telegraph, or a steam engine, or a phonograph, or a photograph, or a telephone or any other important thing—and the last man gets the credit and we forget the others. He added his little mite — that is all he did. These object lessons should teach us that ninety-nine parts of all things that proceed from the intellect are plagiarisms, pure and simple; and the lesson ought to make us modest. But nothing can do that."

"Man has been here 32,000 years. That it took a hundred million years to prepare the world for him is proof that that is what it was done for. I suppose it is, I dunno. If the Eiffel Tower were now representing the world's age, the skin of paint on the pinnacle-knob at its summit would represent man's share of that age; and anybody would perceive that the skin was what the tower was built for. I reckon they would, I dunno."

"A critic never made or killed a book or a play. The people themselves are the final judges. It is their opinion that counts. After all, the final test is truth. But the trouble is that most writers regard truth as their most valuable possession and therefore are most economical in its use."

"Humor must not professedly teach, and it must not professedly preach, but it must do both if it would live forever. By forever, I mean thirty years."

"Always acknowledge a fault frankly. This will throw those in authority off their guard and give you opportunity to commit more."

"Clothes make the man. Naked people have little or no influence on society."

"We all do no end of feeling, and we mistake it for thinking. And out of it we get an aggregation which we consider a boon. Its name is public opinion. It is held in reverence. Some think it the voice of God."

"You tell me whar a man gits his corn pone, en I'll tell you what his 'pinions is."

"The easy confidence with which I know another man's religion is folly teaches me to suspect that my own is also."

"Adam's temperament was the first command the Deity ever issued to a human being on this planet. And it was the only command Adam would never be able to disobey. It said, "Be weak, be water, be characterless, be cheaply persuadable." The later command, to let the fruit alone, was certain to be disobeyed. Not by Adam himself, but by his temperament — which he did not create and had no authority over."

"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."

"I haven't a particle of confidence in a man who has no redeeming petty vices whatsoever."

"Thunder is good, thunder is impressive; but it is lightning that does the work."

"I have been complimented many times and they always embarrass me; I always feel that they have not said enough."

""In God We Trust." Now then, after that legend had remained there forty years or so, unchallenged and doing no harm to anybody, the President suddenly "threw a fit" the other day, as the popular expression goes, and ordered that remark to be removed from our coinage. Mr. Carnegie granted that the matter was not of consequence, that a coin had just exactly the same value without the legend as with it, and he said he had no fault to find with Mr. Roosevelt's action but only with his expressed reasons for the act. The President had ordered the suppression of that motto because a coin carried the name of God into improper places, and this was a profanation of the Holy Name. Carnegie said the name of God is used to being carried into improper places everywhere and all the time, and that he thought the President's reasoning rather weak and poor. I thought the same, and said, "But that is just like the President. If you will notice, he is very much in the habit of furnishing a poor reason for his acts while there is an excellent reason staring him in the face, which he overlooks. There was a good reason for removing that motto; there was, indeed, an unassailably good reason — in the fact that the motto stated a lie. If this nation has ever trusted in God, that time has gone by; for nearly half a century almost its entire trust has been in the Republican party and the dollar–mainly the dollar. I recognize that I am only making an assertion and furnishing no proof; I am sorry, but this is a habit of mine; sorry also that I am not alone in it; everybody seems to have this disease. Take an instance: the removal of the motto fetched out a clamor from the pulpit; little groups and small conventions of clergymen gathered themselves together all over the country, and one of these little groups, consisting of twenty-two ministers, put up a prodigious assertion unbacked by any quoted statistics and passed it unanimously in the form of a resolution: the assertion, to wit, that this is a Christian country. Why, Carnegie, so is hell. Those clergymen know that, inasmuch as "Strait is the way and narrow is the gate, and few — few — are they that enter in thereat" has had the natural effect of making hell the only really prominent Christian community in any of the worlds; but we don't brag of this and certainly it is not proper to brag and boast that America is a Christian country when we all know that certainly five-sixths of our population could not enter in at the narrow gate."

"Laws are sand, customs are rock. Laws can be evaded and punishment escaped, but an openly transgressed custom brings sure punishment."

"Customs do not concern themselves with right or wrong or reason. But they have to be obeyed; one reasons all around them until he is tired, but he must not transgress them, it is sternly forbidden."

"A powerful agent is the right word. Whenever we come upon one of those intensely right words in a book or a newspaper the resulting effect is physical as well as spiritual, and electrically prompt."
