For me, the body/soul problem is fascinating one, which at the moment has no satisfactory resolution. I've been involved with neural networks research for some time, and have lately been getting more into the biological aspect in some depth, so the problem has a certain amount of immediacy to me.
As a theological question, it's one that needs persuing, although speculations about the nature of the mind must be rested on a firm footing. We cannot, for example, divorce the material aspect of our beings from our spiritual aspect. The mechanisms of memory and learning are known to be physical in nature, as is much of what makes us 'us'. For example, damage to certain parts of the brain may result in dramatic personality changes, as will the use of certain drugs. Loss of cognitive ability as a result of brain damage is also well known, and the type of loss depends on what part of the brain is affected.
At the same time, more and more of what we know of brain function can be discussed in computational terms. From the behaviour of single cells to emergent phenomena such as depth perception and auditoy segregation, we are able to see the power of the brain as a computational unit. This doesn't mean that everything is expressible in such terms of course. Aside from the theologians, some famous scientists like Roger Penrose argue that conciousness is fundamentally non-computational in nature. Penrose's theories are controversial, but have been given serious consideration in scientific circles.
The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes. Taking this point of view, we may conclude that science is not physics, biology, or chemistry—is not even a "subject"—but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning.

Anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that my ignorance is just as good as your knowledge
