The laws of Nature take precedence of all human laws. The purpose of all human laws is one - to defeat the laws of Nature. This is the case among all the nations, both civilized and savage. It is a grotesquerie, but when the human race is not grotesque it is because it is asleep and losing its opportunity.
Mark TwainEvolution is the law of policies: Darwin said it, Socrates endorsed it, Cuvier proved it and established it for all time in his paper on The Survival of the Fittest. These are illustrious names, this is a mighty doctrine: nothing can ever remove it from its firm base, nothing dissolve it, but evolution.
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.
