I spoke with spirits about the origin and nature of the so diverse pleasures, which exist with such variety that they are beyond number. Some even feel enjoyments from things that are contrary. It was said that it is nothing but the result of a harmony, and harmony, in turn, of a habit of living from which people have derived enjoyment. A harmony that is contrary to true harmony is acquired through habit, for there are some who take pleasure in discords, some only in harmonies, as most people are aware. So that which results from an acquired harmony, is pleasure, and it soothes, and from habit one loves to return into it.
