Is the Self an Illusion?

In this video, Sam Harris states that consciousness is not irreducible to a single state.  In other words, you can’t say consciousness is just a purely subjective experience or a purely objective one.

When you hook up a person to an fMRI for example, and you measure an intense emotion such as fear, you can see the brain correlation.  Although you can see brain activity, you can’t just say that consciousness is simply a function of the brain.  You have to acknowledge both internal and external states in order to capture the full human experience.
