Christianity: immortal soul Fine Doubter. Thank you for all your contributions to this discussion - they are valuable and are appreciated - at least by me. Getting to your last text: I get the impression, and may be wrong, that you want to move into a more mystical and / or aesthetical direction in your attempt to make sense of a soul as a reality. I have a different proposal that I want to put on the table, attempting to maintain that it is possible talk about a "soul" while remaining in the realm of the purely rational. Based on Ryle's concept of a "category mistake" my claim is that Descartes caused all his trouble by placing "soul" in the same logical category as "body". A "body" is a physical entity, open to perception, with various attributes like mass, length, hair color, type of bone structure and others. But, it seems that the same cannot be said about a "soul". If we compare the soul concept with a concept such as "university" it becomes clearer: if I have to show someone around to give him an idea of what a university looks like, I will most probably show him the lecture halls, library, admin. building(s), hostels, cafeteria etc. If, afterwards, this person states, after having seen al these constituent elements of the university that he is still waiting to be shown the "actual university", it is clear that he doesn't understand the concept of a university: to him there needs to be something else, over and above the constituent elements of the university, which is the real / actual university which I failed to show to him. What is happening here is the failure of the person to grasp the difference between concepts belonging to different logical classes / categories. This is, most probably, what happened to Descartes with his mind / body dualism: the mind is not an entity separate from the body, but, together with the body, constitutes a living person(ality). Therefore Ryle calls the Cartesian mind / spirit the "ghost in the machine". Of course, the implication if this view is that it is impossible for an entity like a "soul" to exist which can survive the physical death of the body. I don't know if this make any sense to you?
