- Many people report having near-death and out-of-body experiences.
- The best explanation for (1) is that human persons have immaterial minds (or souls) that can survive the death of their physical bodies.
- No other hypothesis explains (1) as well as the soul hypothesis does.
- (Therefore) Human persons have souls that can survive the death of their bodies.
Now, what if the body can exist without the mind? Would that count as empirical evidence against the idea of an afterlife? Consider patients with severe forms of dementia or Alzheimer's disease. In the advanced stages of these diseases, it might seem natural to think that "the patient's mind is gone," since there are no signs of mental activity. If this is correct, then does that show that, like the physical body, the mind is also perishable?
