Free Will & Dualism

The idea that the argument for free will and separation of mind and body are completely independent of each other is not all that absurd. When examined closer the premise can be that the idea of physicalism can be intertwined with the argument for hard-determinism. Inversely, the thought that dualism and libertarianism are proponents of each other can also be argued for. Separation of the mind and body makes all the difference between barrier of acting according to natural laws and causal events or instigation of said events through agent causation in the brain.

Lets look at the idea of physicalism and hard-determinism. A steadfast hard-determinist such as Hume argues for the logical process of event-causality; that is to say a stream events influences the apparent 'choice' of the an intelligent being. When acting within natural laws the phsyiological contingencies provide easier clarification of sequence of events. One example in the identity theory, that mental states are identical to physical states (pain and the stimulation of c-fibers). By comparing folk psychology to a scientific psychology it is apparent that through a scientific psychology and understand of the brain we can determinedly predict the actions of a human through their traits, desires, habits, etc. via a complete understanding of the neurological processes and union of mind and body. As suggested, if a child is a raised to understand these physiological and mental processes at a complete neuro-scientific level the child would be able to predict the 'decisions' of another human eliminating any hint that the person had a choice of will.
This was instituted in the idea of "Mary Don't Know". Living in a black and white room being taught all the physical knowledge of colour, a similar understanding would allow us to predict Mary's reactions to the colour green when observed for the first time; Mary herself, would know what to expect.

However, there is the objection that knowledge is intentional. Complete physical knowledge is a different kind of knowledge. Physical knowledge is factual, where as Mary upon experiencing green for the first time gains a knew type of knowledge, both competent and acquaintance knowledge. This new light shows that there is an equivocation of knowledge, and further more that her experience is something new and felt inherently, causing her decisions to be determined internally as to how she reacts to colours. Her decision how to react cannot be predicted as it is a proponent of agent-causation (immanent causation according to Chisholm). By acting of her own accord despite the series of events reinforces her mind-body duality; her consciousness is related to non-physical properties - The Qualia Problem (as according Jackson). Ergo, the divide between the Dualism argument and the Free Will argument is not as big as expected, while the ties may be vast, the correlation is definitely apparent.
