Value is the way animal interest and partiality are experienced in consciousness. As such, they involve a relation between objects of pursuit, animal tendencies and the intuited moral essences the psyche projects on what it seeks. We cannot speak of virtue and vice, therefore, without taking the needs and the desires, the very nature of the animal into account. These natures are diverse and changeable; any overlap between them is a contingent matter of fact. Moral truth thus becomes empirical truth about morality, a prosaic catalogue of who prizes what, a record of the moral history of the world rather than a guide to its correct development.
