In a recent podcast, Walter Bradley Center director Robert J. Marks explored with neurosurgeon Michael Egnor a variety of questions like “From the perspective of a brain surgeon, is there evidence for a soul? Is there evidence for a spirit?” But what is the difference between the two?

A partial transcript follows:
Robert J. Marks: Is there a difference between the soul and the spirit? Do we have a spirit? What does neuroscience say there? Or are they equivalent in some sense?
Michael Egnor: The reality of the soul or the spirit depends, to some extent, on how you define them. And the classical Thomistic way — from St. Thomas Aquinas, of understanding soul and spirit, I think, is the way that makes the most sense. And the soul was understood in much the same way that Aristotle understood the soul as being the principle of life in a living thing. It’s everything that makes you alive rather than dead. So if you look at a living body and compare it to a dead body, the difference is the soul. It’s a principle of organization, a principle of function.
And the spirit, in the Thomistic viewpoint, is the aspects of the soul that are not material. And that would be particularly the intellect and the will. Loosely speaking, the soul is the principle of life in a body and the spirit refers more to the immaterial aspects of the soul, which are the ability to reason and the ability to make decisions based on reason.
Egnor went on to discuss the way in which the research of pioneering neurosurgeon Wilder Penfield (1891–1976) highlighted the existence of the soul . (4:24)
