Essentialism, Metaphysical Realism, and the Errors of Conceptualism

Abstract

Metaphysical realism is the view that most of the objects that populate the world exist independently of our thought and have their natures independently of how, if at all, we conceive of them. It is committed, in my opinion, to a robust form of essentialism. Many modern forms of anti-realism have their roots in a form of conceptualism, according to which all truths about essence knowable by us are ultimately grounded in our concepts, rather than in things ‘in themselves’. My aim is to show that conceptualist anti-realism is an incoherent doctrine and how we can support metaphysical realism and robust essentialism, while still properly acknowledging the cognitive role of concepts in mediating our grasp of the nature of mind-independent reality.
