 A terminological complication is introduced here by the fact that the fully developed form of an entity is itself also frequently designated as its “nature” (Aristotle, Physics 193b; Politics 1252b). In Aristotle’s teleological metaphysics, this is the entity’s end, “that for the sake of which a thing is” (Metaphysics 1050a; Charles 2000: 259). Thus, a human’s “nature”, like that of any other being, may be either the features in virtue of which it is disposed to develop to a certain mature form or, thirdly, the form to which it is disposed to develop.
