Vitalism is the belief that all living things contain a spirit. Animism is the belief that all things, living or otherwise, do.* A friend recently asked me, which am I? And how do I reconcile that with being an evolutionary biologist?
My answer: Biology is about the physical forms of life, and evolution is about how they got to be the way they are. For that matter, all of the hard sciences are about the physical world. Animism and vitalism are about spirits, which are not physical. What does the one have to do with the other? To me, not a whole lot. Physical form probably influences how a spirit perceives and interacts with the world, but in the end body and soul are separate things.
So what do I think about spirits in general? Well, all living things certainly have them. Not sure about non-living things. There are also spirits that aren't attached to physical forms. Some of them survived their deaths in the physical world; others, I have no idea whether they came from a somewhere or if their there is where they've always been. But the physical plane is not the only one.
I'm not sure whether my friend was satisfied with that answer or not.
*Apparently it's more longwinded than that, with whole philosophical schools of thought behind those concepts, with which I'm completely unfamiliar, so I'll just go with how it was defined to me, as above by said friend.
