Critically evaluate either the doctrine of interactionism or physicalism

Paper details:

According to the doctrine of dualism, the mind is a nonphysical substance. In this way, dualism asserts that the mind is quite different from the physical brain. Moreover, according to a particular brand of dualism referred to as interactionism, the nonphysical mind interacts with the physical body/brain. Thus, for example, when one is thinking about writing this essay, the interactionist holds that our thought processes are in some sense nonphysical in character while still being tied to the brain in necessary ways. Physicalism, on the other hand, asserts just the opposite of dualism. According to physicalism, the mind is purely a physical substance. Said differently, the mind is the brain. Under this account of the mind-body problem, of which there are different types, all processes that we would typically refer to as mental in character (thinking, doubting, questioning, dreaming, consciousness, unconsciousness) are merely underlying brain processes in action, i.e., particular configurations of neurons firing in a manner that is governed by natural law. Essay Question: Critically evaluate either the doctrine of interactionism or physicalism. In other words, which view gives a more plausible answer to the fundamental question raised by the mind- body problem? Note that one can examine physicalism as a whole or restrict the scope of your essay to a particular type of physicalism.
