 Ginsborg (2001) attempts to resolve the problem of coherence by appeal to a conception of purposiveness as normativity (see  Section 3.1  above), arguing that organisms can be regarded as subject to normative standards without supposing that they were designed to accord with those standards. Alternative solutions are offered by Kreines (2005), who agrees that the notion of a purpose has normative content but denies that organisms for Kant are in fact purposes, and by Beisbart (2009), who argues that the appeal to normativity is unnecessary for making sense of organisms as natural purposes, since we can conceive of a natural object as artefact-like by conceiving of its parts as produced reciprocally by one another and by the whole (in the way illustrated by Kant through the example of the tree at §64). Gambarotto (2018: 14–22) addresses the problem by denying that Kant’s notion of a natural purpose is coherent; Kant, according to Gambarotto, holds an “unstable” view, because he was unable to free the notion of teleology from that of intention.
