The Mind-Body Problem

Rene Descartes’s distinction between the mind and body was that the mind is a non-extended, thinking thing; and the body is an extended thing which does not think. It is a distinction between the mind and the body that many people maintain; however it creates unavoidable problems, the main one perhaps being how an non-extended object can interact with an extended object?

The limitation of science in describing the relationship between body and mind does not outweigh its ability to identify mechanisms and relationships between the two constructs. There is no proof for a mind existing without a body. For the most part, any organism with a brain structure has a mind of some kind. It may also be safe to assume all organisms with a mind are having profoundly different experiences. But as biologically manifest phenomena in the same universe, we must all have a common factor to our existence, which is our functionality.

The impression of the external world is projected internally. The sense or result of chemical interactions, i.e. reactions in the body to stimulus, create a subjective experience that perceives events, this we identify by observing behavior we relate to that of an object possess of a subjective experience or a mind. Our complex structure of chemical interactions resulted with sensations, drives, and intelligence; none of which appear to be beyond the capacity of physics. Physics is a description of a kind of motion; sensations, drives, and intelligence are all known by a relationship to an object or behavior. All minds are known by their relationship to a body. We have never seen a mind that has no body (even ghost have a form or behavior which makes their presence known). If we have never seen a non-extended object, how can we say such a thing exist? All things known must exert some kind of observable force for us to identify its existence.

There is no physical law that claims nature can not create a thinking object. Why can’t the body think? A mind isn’t extended because it is an action or function; not an object in space, but rather a characteristic inferred by the behavior of an object, i.e. the body. People typically say we use our minds; as if it is a tool we use. And we do not say concepts such as eating or walking are objects, we say they are descriptions of actions, i.e. motions of objects. In both cases the mind is related to something it is external to and also subjected to, which is the body.

The mind must be a product of a tangible object; for a non-extended force can not interact with an extended force, only extended forces can interact. Extension would indicate a multitude of particles, which would appear as a mass of some magnitude. Whereas a non-extended force is no particles, or perhaps one or a few. And we know extension is merely a characteristic of space and time. Thought is a brain function, and a brain is a multitude of particles arranged in a specific manner. Though we don’t have a complete model of the motions of all the particles that make a brain, when can correlate specific parts to specific functions.

The distinction Descartes appears to be making is between agent and action. Consciousness isn’t producing the phenomena of having a body, it is a function of the biological machine, viz. an active brain structure, typically within a body. It can feel as if the mind is outside the body, because there are many body states which result in different mental states, one such state creates a feeling of distance from the body. Is this surprising, considering that various chemicals can manifest a variety of particular bodily, and consequently mental, states? Anything that can be considered to possess the characteristic of a mind must be in some way expressing this possession through the utilization of energy/matter.
