Thomas More's Utopia is considered a classic of political theory because of how effectively he uses the concept of an ideal society to provide a trenchant critique on his own world. In contrast to his own surroundings (Tudor England) Utopia was free of material concerns and greed, as everyone shared material goods, even giving up their homes to someone else every decade. There were no idle people, unlike the contemporary nobles that More loathed. There was no religious strife, in contrast to Reformation Europe. Of course the society in Utopia is unattainable (that's why he named it Utopia, or "no-place" in Greek.) But the point was to stimulate discussion about poverty, religious feuds, the effects of enclosure, and a parasitic nobility in More's own society by contrasting it with an ideal world.
