Hume’s Functionalism

Abstract:This paper claims that Hume is committed to a rather sophisticated form of functionalism. This claim is based upon the following arguments: first, Hume’s characterization of objects such as vegetables and animal bodies in terms of their functional identity, and their underlying analogy with the identity we ascribe to persons or selves, implies that an absolute constancy is not part of the essential nature of persons. Rather, what corresponds to this assumed metaphysical constancy is functional identity. Second, Hume’s distinction between the question concerning the substance of the mind on the one hand, and the questions concerning the local conjunction and cause of our perceptions, on the other, has much in common with, and anticipates, the much-celebrated functionalist distinction between the ontology and metaphysics of the mind.
