Utopian ideals before there were 'Hippies'.

Left panel (The Earthly Paradise – Garden of Eden) from Hieronymus Bosch's The Garden of Earthly Delights.

Chronologically, the first utopian proposal is Plato's Republic.^[1]

Part conversation, part fictional depiction, and part policy proposal, it proposes a categorization of citizens. into a rigid class structure of "golden," "silver," "bronze" and "iron" socioeconomic classes. The golden citizens are trained in a rigorous 50-year long educational program to be benign oligarchs, the "philosopher-kings." The wisdom of these rulers will supposedly eliminate poverty and deprivation through fairly distributed resources, though the details on how to do this are unclear. The educational program for the rulers is the central notion of the proposal.

There is a general pacifism or pacifist attitude. However, the people of the Republic are all ready to defend themselves or to compete militarily for resources (such as land) if necessary. It has few laws, no lawyers and rarely sends its citizens to war, but hires mercenaries from among its war-prone neighbors (these mercenaries were deliberately sent into dangerous situations in the hope that the more warlike populations of all surrounding countries will be weeded out, leaving peaceful peoples).

The society of Plato encourages tolerance of all beliefs.  (Including atheists, pagans, etc - a 2000 year old lesson here for the fundamentalists?)
