Questions to ask a hardcore materialist/reductionalist

Is human awareness identical with the electrical wave of excitation that travels down the axon? Or is it identical with the movement of vescicles carrying electrotransmitters in the presynaptic neuron? Or perhaps with the movement of these neurotransmitters across the synapse? Or perhaps with the excitation of the post-synaptic dendrite?
If human awareness is strictly identical with just one of these, then it follows that what appears to be one experience had by one human is really the sum of billions of interactive sub-human atom-experiences.
If human awareness is identical with one or many of these interacting as they do solely in virtue of what they have in common with chemical reactions outside the body, then it would follow that chemical reactions outside of the body are instances of consciousness as well. If the movement of calcium inside the cell wall of the presynaptic neuron is really an aspect of awaraeness, then the movement of calcium molecules outside a living being is an instance of awareness as well. A different sort of awareness, to be sure, b/c of the chemical differences. But a kind of awareness nevertheless. There are many very diverse electro-chemical-mechanical processes going on in an active neuron. If each of these is an aspect of awareness, then there are many qualitatively different awarenesses in us... and outside of us as well.
If the strictest form of materialism is true (one w/o even emergent properties) then everything is alive.... or dead.

P F Strawson's Freedom and Resentment: the argument laid out

Here is a summary and comments on the essay Freedom and Resentment by PF Strawson.  He makes some great points, and when he is wrong, it is in such a way as to clarify things a great deal.  My non-deterministic position is much better thanks to having read this.  I’ll summarize it in this post and respond in a later one. In a nutshell: PFS first argues that personal resentment that we may feel toward another for having failed to show goodwill toward us would have no problem coexisting with the conviction that determinism is true.  Moral disapprobation, as an analog to resentment, is likewise capable of coexisting with deterministic convictions. In fact, it would seem nearly impossible for a normally-constituted person (i.e., a non-sociopath) to leave behind the web of moral convictions, even if that person is a determinist.  In this way, by arguing that moral and determinist convictions can coexist in the same person, PFS undermines the libertarian argument ...

response to friend who suggested that the self is a democracy of neural parts

This is a nice way to try to avoid being cornered re the irreality of the self if you're a reductionist, for you can assert that a pattern obtains at the microscopic level that is not all that unlike the pattern found at the societal level.  No need for the one self that does it all: instead, you have many sub-selfs that compete for dominance or take turns guiding the whole. The problem with this is, however, that the voters/officials are all zombies.  None of them thinks about the whole as such.  And perhaps none of them thinks even about themselves (unless one is a panzoist).  None of them makes a comparison of alternatives. The more this proposed democracy seems like a zombocracy, the more consciousness will be seem to be epiphenomenal. Furthermore, if the oneness of the self is less real than the multiplicity of explanatory neural parts, then why can't each of these neural parts be conceived of as democracy as well?  And why not parts of these parts, et...

interesting article by Jimmy Akin on death before the Fall

http://www.ncregister.com/blog/jimmy-akin/did-animals-die-before-the-fall/ Akin below: Aquinas.... writes: In the opinion of some, those animals which now are fierce and kill others, would, in that state, have been tame, not only in regard to man, but also in regard to other animals. But this is quite unreasonable. For the nature of animals was not changed by man's sin, as if those whose nature now it is to devour the flesh of others, would then have lived on herbs, as the lion and falcon. Nor does Bede's gloss on Genesis 1:30, say that trees and herbs were given as food to all animals and birds, but to some. Thus there would have been a natural antipathy between some animals  [ Summa Theologiae I:96:1 ad 2 ].  Aquinas thus holds that it was not  all  death that entered the world through man's sin, but human  death.
