What is the mind? And what is its relationship with the body? Philosophers, psychologists, cognitive scientists and neuroscientists have all attempted to bring their professional heft to bear on the “mind-body problem”, but consensus remains elusive. At best, mainstream academics and researchers share a metaphysical commitment: the belief that the seemingly immaterial mind emerges from ordinary matter, specifically the brain. This position — known as materialism or physicalism — has replaced mind-body dualism as the mainstream academic position on the mind-body problem. According to dualism, mind and matter are completely separate substances, and mind (or soul, or spirit) merely inhabits matter. Dualism is a problematic position because it doesn’t offer a clear explanation of how the immaterial mind can causally interact with the material body. How can the immaterial soul push the buttons in the body’s control room… if it doesn’t have hands?
Materialism avoids this issue by denying the existence of two separate substances — mind is matter too, and is therefore perfectly capable of influencing the body. But having made this claim, many materialists promptly forget about the influence of the mind on the body. There seems to be a temptation to skip the difficult step of linking complex mental phenomena with neural processes. Many people think this step is just a matter of working out the details, and they readily replace mental terms like ‘intention’, ‘attitude’, or ‘mood’, with terms that seem more solid, like ‘pleasure chemical’, ‘depression gene’, or ‘empathy neuron’. But these concepts have thus far proved woefully inadequate for constructing a mechanistic theory of how the mind works. Rather than explaining the mind, this kind of premature reductionism seems to explain the mind away. While we work out the details of how exactly the brain gives rise to intentions, attitudes, and moods, we should not lose sight of the fact that these kinds of mental phenomena have measurable influences on the body.
Recent studies linking epigenetics, neuroscience and medicine reveal that subjective experience can have a profound impact on our physical and mental well-being. Mounting evidence is telling us something that was often neglected in the incomplete transition from dualism to materialism — that the mind is a crucial material force that influences the body, and by extension, the world outside the body.
