One day man by the slow processes of evolution shall develop into something really fine and high - some billions of years hence, say.
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.
Mark TwainTo 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.
