Compare and contrast Descartes’ view of the mind with Churchland’s or Noe’s.

Topic – Descartes famously argues in his Meditations that the mind is more knowable than the body, but more contemporary figures such as Alva Noe and Paul Churchland have respectively argued that the mind is in fact reducible to the body or to the brain. For your essay, compare and contrast Descartes’ view of the mind with Churchland’s or Noe’s. Is the mind really separate from the brain/body, and if so, why? If not, then what does this mean for Descartes’ contention that the mind is the only thing that cannot be doubted?
