Material unity and natural organism in Locke

This paper examines one of the central complaints regarding Locke's Essay, namely, its supposed incoherence. The question is whether Locke can successfully maintain a materialistic conception of matter, while advancing a theory of knowledge that will constrain the possibilities for a cognitive access to matter from the start. In approaching this question I concentrate on Locke's account of unity. While material unity can be described in relation to Locke's account of substance, real essence, and nominal essence, a separate discussion will be called for altogether in the case of organic unity. In closing, I turn to Kant as a model for locating Locke's purported incoherence, suggesting that his "skeptical idealism" yields the same epistemic advantages as those won by Kant's "empirical realism."
