2 Either/Or

This essay surveys the varieties of disjunctivism about perceptual experience. Disjunctivism comes in two main flavours, metaphysical and epistemological. Metaphysical disjunctivism is the view usually associated with the disjunctivist label, and whenever ‘disjunctivism’ occurs here unprefixed, it refers to this view. After some initial discussion of (metaphysical) disjunctivism (sections 1–3), we explain epistemological disjunctivism in section 4. The rest of the essay is solely concerned with explaining and assessing metaphysical disjunctivism, a theory of the nature of perceptual experience. Our main (and provisional) conclusion is that although there is considerable insight in the vicinity, metaphysical disjunctivism is false.
