After studying all the major solutions to the mind body problem: Dualism, eliminativism, behaviorism, identity theory, functionalism, instrumentalism, I think that Davidson’s Anomalous Monism best encapsulates what I have been arguing on this forum sporadically for years. That is, the mental supervenes on the physical, but is not reducible to the physical.
Davidson’s quite ingenious resolution of the paradox created by this position is worth exploring, even though I am not certain that I completely understand his argument, here goes.
There are three major premises that I hold in common with Davidson, these are:
Causal Interation: Mental events can cause physical events, and vise versa
Nomological character of causality: Causally related events fall under laws
Anomalism of the Mental: There are no strict psychophysical law
The paradox is obvious so I will hold off explaining why these three premises seem contradictory unless asked to do so.
The resolution of the problem is, in true Davidsonian fashion, vague and ambiguous, but it is along the lines that mental events are mental events only insofar as they are described that way. They can be described in both physical and mental terms ,and while psychophysical causation requires laws, it does not require psychophysical laws. That is, if you want to say “I desire X” causes you to go get “X”, there is no requirement that “I desire X be described in mental terms. Instead for this example to instantiate a law, it must be described in terms of the physical. “Neural pattern Y”(associated with desire of X” causes the behavior of obtaining “X”.
More to the point, mental and physical properties are apriori incompatible. That is, mental connections in the general sense are related according to logic, reason, intentional states ect., while physical events are related in terms of physical laws like F=MA, gravity, inertia ect. Nomological laws require properties that are apriori compatible. That is, if events instantiate a law, they have to appeal to the same kind of properties. As such, any bridging laws between the mental and the physical will impose mental properties on physical processes and vice versa…thus will be incoherent and confused.
By way of an analogy
When sodium and water mix there is a violent reaction. Agent X pours Kool Aid onto Sodium and concludes that there is a law that says Kool Aid + Sodium = explosion. When infact it is water+Sodium=explosion. Agent X has used improperly described the law.
He is employing incompatible descriptions. Kool Aid will always cause sodium to react, but there is no law that says Kool Aid + sodium=reaction. KoolAid, afterall, is a brand name that does not reference physical properties, namely H2O, thus any law between sodium and koolaid would be confused.

A.M. applies to intentional states but not sentient states. Desire,beliefs, wants, attitudes, but not pain, tickle, itch ect.
