No, unless by 'soul' you mean the mental manifestation of consciousness. I frankly find a metaphysical soul to be hard to believe, simply because personality can be so easily be altered through physical means. I've personally seen how medication can drastically affect emotion, how head injuries can completely warp how a person thinks, or how just emotional trauma alone can effectively program new behaviours into a person. The idea that someone has a consistant, everlasting soul just doesn't fit into that picture very well.
