The real question should be do people have souls? It's not like I don't have one while everyone else does! I'm not Satan's little helper.

While some are convinced they do have a soul I think its only because they have been conditioned to believe that through a lifetime of religious teaching and cultural bias. In the past it used to be believed that the mental activity we now ascribe to our brains, were functions performed by our hearts. (They didn't know or worry what brains were for -- perhaps some kind of blood filter thingie). In those times virtually everyone thought the heart organ did their thinking. Most would have believed the thinking heart 'reality' just as passionately as you good folks who believe in souls. They would have learned the idea the same way you learned to believe in souls.
