 There is no incoherence here on Wiggins’ part because species essentialism is logically independent of individual essentialism. Nevertheless, Wiggins’ essentialism is, like species essentialism, also subject to criticism based on contemporary results from the philosophy of biology (Laporte 1997 and Okasha 2000). But see Ferner (2016) for a sympathetic discussion of Wiggins’ doctrines from the perspective of biology, and Devitt (2018) for a recent defense of individual essentialism, which considers the views and criticism in question.
