I. An approach to the question of teleology in nature for Aristotle requires first of all a sufficiently clear understanding of the terms involved. In regard to the notion of teleology itself, there can hardly be any pertinent difficulty. The term is a modern one, and is quite definitely fixed in meaning by contemporary use. It seems to have been coined in eighteenth-century philosophical Latin to denote the study of final causes in nature. It became readily accepted in modern philosophical (...) vocabulary. Against this historical background it is commonly understood today to focus on “purposive or goal-directed activity.” In application to nature it assumes that purposive activity is present and asks how the activity is to be identified and described. The initial problem, accordingly, will lie not with the notion of teleology but rather with the other term, ‘nature’. (shrink)
