  However, the central principle underlying the Utopians' way of life is that as much time as possible should be reserved for the cultivation of the mind, as it is in this that they consider true happiness can be found (CU: 135). This requirement is met by their extraordinary system of work in which all citizens, of either sex, (and that could amount to about 60,000 in each city) must labour at some essential trade, but only for six hours a day; this more than meets their needs, but still leaves ample leisure for intellectual pursuits.  Every child is grounded in the liberal arts, and most of the adult population, “men and women alike”, devote themselves to further study in their spare time. While there is an elite class of scholars, carefully selected by the priests and approved by the syphogrants, who dedicate themselves to full-time study and are available to hold the higher offices, the lectures provided for them are equally open to all comers. There is a vital cultural life, a direct consequence of their economic arrangements. One of the most vivid episodes in Utopia is the account of the Anemolian ambassadors: these dignitaries, determined to impress the Utopians, deck themselves out in conventional finery—cloth of gold, gold chains and rings, jewelled badges—only to find that the Utopians regard them as slaves or fools. This is because of the Utopian value system, which uses such impractical metals for shackles or chamber pots: it is an essential part of their humanist education to recognize authentic values, not the pseudo-values imposed by social conspiracy but those deriving from nature itself. The fact that they need very few laws comes from the effectiveness of this early formation (CU: 195).
