This is a response to two articles by William Charlton and Nicholas Lash. These authors criticize a view which they attribute to Descartes. According to this view, there is a dualism of mind and body. In this paper it is argued, first, that some form of dualism is intrinsically plausible, second, that the view these authors attribute to Descartes is not one he held and, third, that a dualism of mind or soul and body has always been central to the Christian faith. It concludes by considering Charlton's attempt to elucidate the Christian belief in an after life by reference to what he calls a process of divinisation. The importance of this process is not denied. It is argued, however, that it must itself involve a dualism of mind or soul and body.
