"Scientific societies are as yet in their infancy. It may be worthwhile to spend a few moments in speculating as to possible future developments of those that are oligarchies.
...Diet, injections, and injunctions will combine, from a very early age, to produce the sort of character and the sort of beliefs that the authorities consider desirable, and any serious criticism of the powers that be will become psychologically impossible. Even if all are miserable, all will believe themselves happy, because the government will tell them that they are so.
A totalitarian government with a scientific bent might do things that to us would seem horrifying. The Nazis were more scientific than the present rulers of Russia, and were more inclined towards the sort of atrocities that I have in mind. They were said - I do not know with what truth - to use prisoners in concentration camps as material for all kinds of experiments, some involving death after much pain. If they had survived, they would probably have soon taken to scientific breeding. Any nation which adopts this practice will, within a generation, secure great military advantages. The system, one may surmise, will be something like this: except possibly in the governing aristocracy, all but 5 per cent of males and 30 per cent of females will be sterilised. The 30 per cent of females will be expected to spend the years from eighteen to forty in reproduction, in order to secure adequate cannon fodder. As a rule, artificial insemination will be preferred to the natural method. The unsterilised, if they desire the pleasures of love, will usually have to seek them with sterilised partners.
Sires will be chosen for various qualities, some for muscle others for brains. All will have to be healthy, and unless they are to be the fathers of oligarchs they will have to be of a submissive and docile disposition. Children will, as in Plato's Republic, be taken from their mothers and reared by professional nurses. Gradually, by selective breeding the congenital differences between rulers and ruled will increase until they become almost different species. A revolt of the plebs would become as unthinkable as an organised insurrection of sheep against the practice of eating mutton. (The Aztecs kept a domesticated alien tribe for purposes of cannibalism. Their regime was totalitarian.)
To those accustomed to this system, the family as we know it would seem as queer as the tribal and totem organisation of Australian aborigines seems to us... The labouring class would have such long hours of work and so little to eat that their desires would hardly extend beyond sleep and food. The upper class, being deprived of the softer pleasures both by the abolition of the family and by the supreme duty of devotion to the State, would acquire the mentality of ascetics: they would care only for power, and in pursuit of it would not shrink from cruelty. By the practice of cruelty men would become hardened, so that worse and worse tortures would be required to give the spectators a thrill."
