Medical science does not know what life is, but it is very careful to distinguish it from death just the same, and very little inclined to question the reality of the phenomenon on the grounds that it lacks a satisfactory account of it. Neuroscience does not know what the mind or the self is, and has made a project of talking them out of existence for the sake of its theories which exclude them. They have banished the dichotomy called Cartesian by excluding one major term, the mind, that is.
