 Kant thinks that this is the case in particular for organisms, which are “natural purposes” (see  Section 3.3  below). But the notion of purposiveness also applies more broadly, and Kant distinguishes various different kinds of purposiveness applying not only to organisms and artifacts, but also to beautiful objects, to nature as a whole (both in so far as it is comprehensible to human beings, and in so far as it is a system of purposes standing in purposive relations to one another), to the functioning of our cognitive faculties in aesthetic appreciation and empirical scientific enquiry, to geometrical figures, and even to objects that are useful or agreeable to human beings.
