Full Idea
Central to Locke's account of the self is the idea that consciousness is reflexive and that it plays a dual role in self-constitution: it is what unifies a person not only over time, but also at a time.

A Reaction
This is a good explanation of Locke's view, and shows clearly why Locke does not hold a 'memory' theory (unless, of course, one held the view that all consciousness is memory). Consciousness unites self, or self unites consciousness?
