 In addition to the community of goods and the painted walls, another characteristic feature of the City of the Sun, one that is more difficult and disconcerting and that Campanella himself describes as “hard and arduous”, is the community of wives. This is the solution adopted by the citizens to the problem of generation. Echoing the teaching of the Pythagorean Ocellus Lucanus, Campanella says that they are amazed that humans are preoccupied by the breeding of horses and dogs while neglecting their own. The act of generation entails a large responsibility of the part of the parents; and if it is exercised in an incorrect manner, it can give rise to a long chain of suffering. Moreover, there is a close connection between a person’s natural “complexion” or character, which is inborn and not afterwards modifiable, and moral virtue, which needs a suitable terrain in order to take root and prosper. Generation should therefore respect precise norms and not be entrusted to chance nor to individual sentiments. The citizens distinguish between love and sex. Affection between men and women, based on friendship and respect more than sexual attraction, is expressed in acts that are far removed from sexuality, such as exchanges of gifts, conversation and dancing. Sexual generation, on the other hand, must obey strict rules regarding the physical and moral qualities of the parents and the choice of a propitious time for conception, determined by an astrologer. Such a union is not the expression of a personal, emotional or passionate relationship, but rather is connected to the social responsibility of generation and to love for the collective community.
