 Referencing Leibniz, Kant adapted this dualistic scheme into his own scheme of transcendental ideas. In nature, everything happened accord to laws, though the course of the world might depend on a somewhat richer ontology, including lawfully-acting generative forces for the formation of plants and animals, than Leibniz had allowed for, forces that human beings might never really understand. At the same time, rational beings, though not other souls or minds, formed a moral community (see Guyer).
