There is no reason whatever to believe that the order of nature has any greater bias in favour of man than it had in favour of the ichthyosaur or the pterodactyl.
H. G. WellsI believe that now and always the conscious selection of the best for reproduction will be impossible; that to propose it is to display a fundamental misunderstanding of what individuality implies. The way of nature has always been to slay the hindmost, and there is still no other way, unless we can prevent those who would become the hindmost being born. It is in the sterilization of failure, and not in the selection of successes for breeding, that the possibility of an improvement of the human stock lies.
