The battle between the mechanist and vitalist continues. The problem is simple. We, the vitalists, cannot prove this immaterial thing we call innate intelligence and the mechanists cannot demonstrate the concept of life by virtue of chemistry and physics alone. They say that they are getting closer and one day will. Our thinking is such that until they can create a living cell with chemicals in a test tube, we accept that there is an immaterial factor and will continue to base our practice on that. If the time should ever come that they prove life is nothing more than a mechanistic phenomena, we will rethink our position. Until that day comes, they should cease attacking us for not proving the unprovable and go out and prove what they say is provable. The burden of proof rests upon them.v16n1
