(Barcalow, pg. 76). So at what point in time didthe nonphysical mind and consciousness exist? Did the dinosaurs have minds, or asDescartes believed, did the mind only exist with human evolution? This we cannotanswer. We have yet to find out when in fetal development the nonphysical mind exists.Answering these objections is a tough task. For the first one, we can say that themind is the only nonphysical entity that can create energy and force. There doesnt seemto be anything else that is nonphysical that can create energy, except the mind. Thesecond objection is somewhat easier to answer. Just because we cant see it, doesntmean it doesnt exist. A majority of the population of the world believes in some sort ofGod or higher power, but we scientifically cant prove that one exists. There might be aGod, but we really dont know for sure. So why cant we believe in Descartes theory ofSubstance Dualism? The third objection is the toughest to answer. We as people justhave to assume that at some point in fetal development, our brain grows to become socomplex, that the mind and consciousness become one with our brain.I, myself, believe in Substance Dualism and Interactionism. I dont think there isreally any other way to explain the relationship between our physical body andnonphysical mind. Descartes makes sense in his theory and the objections Barcalowcame up with can be answered. Unless someone comes up with a theory that is better andcan disprove Descartes, Im sticking with Descartes. I mean, something told my handswhat to type.Overall, the mind and body relationship is a tricky subject. We as humans dontfully know where the nonphysical properties of our mind came from nor do we know ifone exists. So far, Descartes came up with the best theory to explain it, but not everyonebelieves it. There are also a few objections to his theory that raise questions as to if it can be believed. I believe Descartes was a man truly ahead o...
