Abstract
In his Treatise of Human Nature, David Hume asked how people succeed in constructing edifices of belief from their limited store of sensory impressions and derived ideas. Hume could adduce no evidence to support the existence of an inner self that intelligently manipulates impressions and ideas. At the same time, he recognized in himself the conviction that there is inner self. Today, there is a growing conviction among cognitive neuro-scientists, behavioral scientists, science journalists, and their publics that neuroscience is on the verge of providing us with the ultimate solution to ‘‘Hume’s problem.’’ This article describes two approaches to this solution.
