The one major work preceding More's in the field was Plato's Republic. Its influence on Utopia is extensive and unmistakable. To begin with, the central theme of both works is the search for justice. In the Republic, the rulers are to be a group of intelligent, unselfish men called the guardians or philosopher-kings, who conduct public affairs for the good of the whole nation. The principle of community of property is in effect: "No man calls anything his own." Gold and silver coinage is outlawed, and there is a rigid proscription against luxury and ostentation. Throughout the society, life is directed by a highly moral code of conduct. An educational system for the intelligentsia is elaborately and idealistically designed. Equality of men and women is proposed in both works, though with certain qualifications. There is allowance made in Plato's scheme for the practice of slavery, as there is in More's. There are, on the other hand, departures from Plato in Utopia, some quite radical. The Republic establishes sharply defined class distinctions — the ruling intelligentsia; the warrior class; commoners, consisting of merchants, artisans, and laborers; and finally, at the lowest level, the slaves. Utopians recognize no such gradations among their citizens. The religious beliefs and practices in the two books are, of course, quite different. There is also a sharp difference in the treatment of families. In the Republic, women and children are held in common — "there is no marrying nor giving in marriage" — and mating is regulated to serve eugenic ends; whereas in Utopia, the family unit is the core of the entire social structure.
Sir Francis Bacon, New Atlantis. Although he never completed it, this utopian novel by one of the great philosophers of the Elizabethan and Jacobean eras is well worth reading. It was published posthumously in 1627 and outlines a perfect society, Bensalem (its name suggesting Jerusalem) founded on peace, enlightenment, and public spirit. Available in Three Early Modern Utopias Thomas More: Utopia / Francis Bacon: New Atlantis / Henry Neville: The Isle of Pines (Oxford World’s Classics) along with More’s Utopia and another early utopian novel, Henry Neville’s The Isle of Pines.
In an essay "Of Cannibals," Montaigne gives an account of a primitive tribe of South American Indians; while treating their life style in toto, he pays special attention to their choice of leaders, their mode of warfare, and their treatment of captives. This work is a notable contribution to the vogue of fictionalized travel literature, which includes, in addition to More's Utopia, such works as Robinson Crusoe and Gulliver's Travels and a host of major and minor later documents. Montaigne's philosophical approach to his subject is revealed in his repeated pointing of contrasts between those simple Indians and "civilized" Europeans with their mechanical progress, their gunpowder, and their Christianity. In almost every instance, civilization comes off second best in matters of rational behavior and especially where man's humanity to man is concerned.
The work begins with written correspondence between Thomas More and several people he had met on the continent: Peter Gilles, town clerk of Antwerp, and Hieronymus van Busleyden, counselor to Charles V. More chose these letters, which are communications between actual people, to further the plausibility of his fictional land. In the same spirit, these letters also include a specimen of the Utopian alphabet and its poetry. The letters also explain the lack of widespread travel to Utopia; during the first mention of the land, someone had coughed during announcement of the exact longitude and latitude. The first book tells of the traveller Raphael Hythlodaeus, to whom More is introduced in Antwerp, and it also explores the subject of how best to counsel a prince, a popular topic at the time.

A Modern Utopia (1905) by H. G. Wells – An imaginary, progressive utopia on a planetary scale in which the social and technological environment are in continuous improvement, a world state owns all land and power sources, positive compulsion and physical labor have been all but eliminated, general freedom is assured, and an open, voluntary order of "samurai" rules.[27]

What happens to those slaves (bondsmen) who helped feed the citizens of Utopia by butchering animals for food and thus suffering the apparent moral consequence of diminished compassion is not stated. Perhaps Utopia uses only slaves gotten from outside the citizenry of Utopia for their necessary killing. Utopia has slaves captured in wars they fought and other "foreigners who have been condemned to death" which the Utopians "acquire [...] sometimes cheaply, more often gratis and take them away." Foreign slaves are kept "constantly at work" and in chains. (95) Utopia also has slaves who entered into slavery by choice. These are "poor, overworked drudges from other nations [...] who chose to be slaves among the Utopians." Such slaves can relinquish their slavery whenever they choose, but in doing so they leave Utopia, although they are not "sent away empty-handed." (96)

There is a kind of state religion in Utopia which includes high priests and public worship. "They invoke God by no other name than Mythras, a name they all apply to the one divine nature, whatever it may be. No prayers are devised which everyone cannot say without offending his own denomination." (126) "When the priest [...] comes out of the sacristy, everyone immediately prostrates himself on the ground out of reverence; on all sides the silence is so profound that the spectacle itself inspires a certain fear, as if in the presence of some divinity." (128) Priests are held in such high esteem that "even if they commit a crime they are not subject to a public tribunal but are left to God and their own consciences. [...] For it is unlikely that someone who is the cream of the crop and is elevated to a position of such dignity only because of his virtue should degenerate into corruption and vice." (124)
Augustine's work set out to defend Christianity against the criticism of proponents of traditional pagan worship. It launches an attack on the pattern of immorality in Roman life under the worship of the pagan gods and offers, in contrast, the way of life taught by Christianity. His arguments are based on his interpretation of history, both Old Testament history and Roman. There is not a specific practical plan for the government of his imaginary ideal state but rather a distinction drawn on philosophical lines between two guiding principles. In the "City of Earth," the love of self holds precedence over love of God; in the "City of God," the love of God holds precedence over the love of self. 

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.

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.
