Foster states the following:
“although the basic subjects involved in human mentality are wholly non-physical, each subject is, at least for a certain phase of its history, intimately linked with a particular biological organism. it is this link which makes it appropriate to speak of the subject as having a body, or as embodied. . . . but what, then, is the nature of this link? what is the connection between the non-physical subject and the biological organism which embodies it? . . . anything approaching an adequate answer to this question . . . would become the business of the neuroscientist. . . . to begin with, it is clear that the connection between the non-physical subject and the biological organism is, fundamentally, a functional one: it is a matter of there being a psychophysical arrangement whereby each partner is equipped to have the right sorts of direct causal influence on the other. this arrangement will be secured by the respective natures of the two entities concerned, together with some framework of physical and psychophysical laws.”
my research has dealt with Foster’s last two sentences in this excerpt. the immaterial mind and the material synaptic networks of the human brain possess specific “natures” and functions which I endeavor to identify and explain, including waveforms, quantum tunneling, action potentials, neural codes and the like!
