"In the long history of humankind (and animal kind, too) those who learned to collaborate and improvise most effectively have prevailed." -- Charles Darwin
Charles Darwin was an English naturalist whose revolutionary theory laid the foundation for both the modern theory of evolution and the principle of common descent by proposing natural selection as a mechanism. He published this proposal in 1859 in the book The Origin of Species, which remains his most famous work.
"A man who dares to waste one hour of time has not discovered the value of life.""A man's friendships are one of the best measures of his worth.""A moral being is one who is capable of reflecting on his past actions and their motives - of approving of some and disapproving of others.""A scientific man ought to have no wishes, no affections, - a mere heart of stone.""An American monkey, after getting drunk on brandy, would never touch it again, and thus is much wiser than most men.""Animals, whom we have made our slaves, we do not like to consider our equal.""At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate, and replace the savage races throughout the world.""False facts are highly injurious to the progress of science, for they often endure long; but false views, if supported by some evidence, do little harm, for every one takes a salutary pleasure in proving their falseness.""How paramount the future is to the present when one is surrounded by children.""I am turned into a sort of machine for observing facts and grinding out conclusions.""I cannot persuade myself that a beneficent and omnipotent God would have designedly created parasitic wasps with the express intention of their feeding within the living bodies of Caterpillars.""I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.""I have tried lately to read Shakespeare, and found it so intolerably dull that it nauseated me.""I love fools' experiments. I am always making them.""If the misery of the poor be caused not by the laws of nature, but by our institutions, great is our sin.""Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.""It is a cursed evil to any man to become as absorbed in any subject as I am in mine.""It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.""Man is descended from a hairy, tailed quadruped, probably arboreal in its habits.""Man tends to increase at a greater rate than his means of subsistence.""My mind seems to have become a kind of machine for grinding general laws out of large collections of facts.""On the ordinary view of each species having been independently created, we gain no scientific explanation.""The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.""The mystery of the beginning of all things is insoluble by us; and I for one must be content to remain an agnostic.""The very essence of instinct is that it's followed independently of reason.""To kill an error is as good a service as, and sometimes even better than, the establishing of a new truth or fact.""We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.""We must, however, acknowledge, as it seems to me, that man with all his noble qualities... still bears in his bodily frame the indelible stamp of his lowly origin.""What a book a devil's chaplain might write on the clumsy, wasteful, blundering, low, and horribly cruel work of nature!"
