Abraham Lincoln and Charles Darwin were born on the exact same day, FEBRUARY 12, 1809, but their lives had completely different effects. Lincoln is best known for freeing the slaves by issuing the Emancipation Proclamation, affirming in his Gettysburg Address, 1863: "a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal." Darwin is best known for the theory of evolution, arguing that men are not only not "created" but they are not "equal" as some are more evolved. In his Descent of Man, 1871, Darwin wrote: "Men...build asylums for the imbecile, the maimed and the sick...thus the weak members...propagate their kind. No one who had attended to the breeding of domestic animals will doubt that this must be highly injurious to the race of man...Hardly any one is so ignorant as to allow his worst animals to breed." Darwin continued: "Civilized races of man will almost certainly exterminate the savage races throughout the world." Whereas Darwin's theory has been used by atheists to explain away God, the last act of Congress signed by Abraham Lincoln before he was shot was to place the phrase "In God We Trust" on all national coin.
