Neuroscience and Free Will

We like to think of ourselves as rational agents who exercise conscious control over most of our actions and decisions. Yet in recent years, neuroscientists have claimed to prove that free will is simply an illusion, that our brains decide for us before our conscious minds even become aware. But what kind of evidence do these scientists rely on to support their sweeping conclusions? Is the "free will" they talk about the same kind of free will that philosophers have puzzled about for millennia? And could science ever prove that we lack the kind of freedom needed for moral responsibility? John and Ken free their minds with Daniel Dennett from Tufts University, author of Freedom Evolves.
