A Brief Refutation of Physicalism (Part 1)
Physicalism is the philosophical belief that the only kinds of things that are real are physical things. Only entities which can be described by physics are considered to exist. Therefore, such things as the soul or an immaterial mind are not real. Physicalism is a form of monism, teaching that the universe, including man, is made of one kind of substance, physical or material. This is the dominant philosophy in academic circles today. In contrast, throughout most of human history, both the educated and uneducated alike have held to a form of dualism, that is, that reality consists of more than just matter and physical laws. Christianity has held for centuries that man is, in the words of Thomas Aquinas…
… composed of a spiritual and corporeal substance.
There are good reasons to accept dualism and reject physicalism as the proper ontology of our existence. I will briefly submit a few of these reasons over the next couple of posts.
For many, modern science has proven that the immaterial mind does not exist. What we call the mind is just a complex organization of matter and chemistry. Is the mind nothing more than a function of the brain? To answer this question, we turn to Leibniz’s law, which states for any X and any Y, if X is identical Y, then for all properties P, P is true of X if and only if P is true of Y. In other words, if a property is true of X which is not true of Y, they are not identical. When applied to the issue at hand, the question becomes, “Are there things which are true of mental states/properties which are not true of physical states/properties?”
Next, I’ll attempt to answer that question.
