Abstract

Intrinsic biological essentialism (INBE) is the view that biological taxa have fixed identity conditions, conditions which consist at least in part of intrinsic properties. After a long period of near universal rejection within both philosophy of biology and theoretical biology, INBE is making a comeback. Here I attempt to support this revival by clarifying the nature of INBE, developing a new argument on its behalf, and addressing an important anti-essentialist critique
