Thanks for your comment. Having studied the mind-body problem fairly extensively, I'm quite happy to trumpet a biblically-informed view of the soul, as well as what we know on the subject from the Christian intellectual tradition. It isn't so much a matter of doubt about the soul's metaphysical status that plagues us as informed Christians; rather it is the knowledge that there are groups--like the Singularity group cited in the article--whose metaphysical assumptions about the soul and human personhood will give rise to new technologies which will give rise to ever-increasingly complex ethical dilemmas. The technology is on its way. What should our response be, and what forms should that response take?
