Utopians are ambivalent, in fact illogical if not morally arrogant, about killing for food or defense. They eat animals but "they do not allow their citizens to be accustomed to butchering animals" but rather have "bondsmen" do this because they believe that butchering animals for food "gradually eliminates compassion, the finest feeling of human nature." (68) Bondsmen are apparently immune to such a descent into moral corruption, or else they are bondsmen exactly because they are already morally degraded and so either immune to further corruption or they are beyond moral rectification, and therefore the moral consequences of killing for food cannot matter for their moral selves. So bondsmen who butcher animals either have no compassion, it having been gradually eliminated through butchering, or because their moral precondition, their qualification of moral impurity, includes diminished compassion from which their moral descent continues, or else they have compassion and, being bondsmen, they are somehow immune from the moral consequences of killing for food, either because of their moral deficiency or because bondsmen have a moral strength that the citizens of Utopia lack.

The optimistic views which the author held regarding the inevitable progress of human society were somewhat undermined by the events of World War I, as is demonstrated in his later writings. He came to question whether or not scientific progress would always achieve social improvement. His warning of the possibility of developing mind control through blatant advertising and through drugs is prophetic.

In the decades immediately preceding Luther's break from the church of Rome, many devout Catholics were vocal in their criticism of practices authorized by the church as well as by the shameful conduct among the clergy. Eventually the critics broke into two groups. Luther and the other leaders of the Reformation, despairing of remodeling the established church with its ingrained fallacies, severed their connections with Rome and declared a new authority. Another party of critics strove for reform within the established church toward which they maintained an absolute loyalty despite its manifest faults. Among them, one of the most articulate and effective writers was Erasmus, More's close friend; and in the same camp, though not expressing his views so vociferously, was More also, whose aspirations toward a more truly Christian way of life are revealed through his plan of Utopia.
The Islands of Wisdom (1922) by Alexander Moszkowski – In the novel various utopian and dystopian islands that embody social-political ideas of European philosophy are explored. The philosophies are taken to their extremes for their absurdities when they are put into practice. It also features an "island of technology" which anticipates mobile telephones, nuclear energy, a concentrated brief-language that saves discussion time and a thorough mechanization of life.
Forbidden Planet (1950) is a movie directed by Fred M. Wilcox, which is today regarded as one of the most influential science fiction movies of all time. Its story revolved around Commander John J. Adams (Leslie Nielsen) in his quest across the stars to find an expedition colony that disappeared 20 years ago. By the end of the movie, he discovered those colonists were killed by the technology created by the long extinct race of aliens, called Krell. They managed to create a machine, which was able to materialize their every dream and help them in establishing perfect utopia. However, same technology led to their extinction when their subconscious fears and monsters also became real.
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.
