Denis Diderot's Supplement to Bougainville's "Voyage" (1772) is a prime example of the eighteenth-century vogue of primitivism which was spurred by Rousseau's thesis of the "noble savage" and which generated such novels as St. Pierre's Paul and Virginia and Chateaubriand's Atala. Diderot's book makes a case for the simple, natural ways of a South Sea Island culture as reported by Bougainville, a French explorer. The central portion of the story presents an imaginary dialogue between a French chaplain and a native of Tahiti (Orou) in which a comparison is made between the customs and institutions of Europe and those of Tahiti. The way of life of the islanders is eloquently defended, and that of the Europeans discredited. According to the Tahitian, man's natural instincts, which are equated with the laws of nature, are interpreted as justifying complete freedom in sexual relations. Their observance of community property is defended as minimizing personal conflicts and legal entanglements and promoting a general concern for the welfare of the community as a whole.
Equality for all mankind is not a realistic goal in Wells's view. That, he believes, would mean a loss of individuality, and individuality is an inherent requirement of human nature. Similarly, competition is necessary to a thriving society. Taking what he considers a practical position, he sees the new society as divided into four classes of persons which he calls poietic, kinetic, dull, and base. There is a leader caste, called Samurai, which is drawn primarily from the poietic group, though some from the kinetic class may qualify. Persons who volunteer for Samurai membership must meet stringent requirements, both physical and mental; and they must pledge to conform to the rules of the caste, which forbid eating meat, smoking, drinking, gambling, and participation in public sports or entertainments. The Samurai furnish the World State with its administrators, legislators, lawyers, doctors, and other leaders. Furthermore, they are the only voters in the commonwealth. The male members of the Samurai are encouraged to marry women of comparable qualifications, and they are encouraged to produce children with the aim of improving the quality of the population. The lower classes of citizens, the dull witted, the criminals, and the deformed are exiled from society and prevented from childbearing.
