I have been scientifically studying the traits and dispositions of the "lower animals" (so-called,) and contrasting them with the traits and dispositions of man. I find the result profoundly humiliating to me. For it obliges me to renounce my allegiance to the Darwinian theory of the Ascent of Man from the Lower Animals; since it now seems plain to me that that theory ought to be vacated in favor of a new and truer one, this new and truer one to be named the Descent of Man from the Higher Animals.
Mark TwainAll Congresses and Parliaments have a kindly feeling for idiots, and a compassion for them, on account of personal experience and heredity.
Mark TwainAs to the human race. There are many pretty and winning things about the human race. It is perhaps the poorest of all the inventions of all the gods but it has never suspected it once. There is nothing prettier than its naive and complacent appreciation of itself. It comes out frankly and proclaims without bashfulness or any sign of a blush that it is the noblest work of God. It has had a billion opportunities to know better, but all signs fail with this ass. I could say harsh things about it but I cannot bring myself to do it-it is like hitting a child.
Mark TwainWhat a wee little part of a person's life are his acts and his words! His real life is led in his head, and is known to none but himself. All day long, the mill of his brain is grinding, and his thoughts, not those of other things, are his history. These are his life, and they are not written. Everyday would make a whole book of 80,000 words -- 365 books a year. Biographies are but the clothes and buttons of the man -- the biography of the man himself cannot be written.
