physicalism and immateriality

The following is an ironic/dialectical argument against the assumption that the mere claim that to every physical state there is a mental state (and vice versa) would, if granted, imply that mental states are not immaterial.

First reply: Mental states may still be thoroughly immaterial, but also capable of downward causality upon physical (this is not my position, but I'm just pointing out the non-sequitur in the physicalist argumetn).

Second reply: Or even if we posit ONLY bottom-up causality, we'd have a superfluous, epiphenomenal, mental state... which would be absurd... but not incapable of existing apart from matter.  Especially if the cognition had somehow transcends the limitations of space and time.

Comment: Yes, the latter does seem to be grasping at straws, and I'm not that inclined to be a dualist.  But I thought it interesting to point out the non-sequitur in the physicalist basis for denying the existence of the non-physical.  And I think it's important to take careful note of the nature of the sort of awareness that seems to make the human psyche a candidate for a non-physicalist understanding.  In knowing or seeking to know about what is true always and everywhere... we seem to transcend material limitations regardless of whether such knowledge also has a multiplicity of possible profiles, each of which corresponds to a material state.

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 ...

Daniel Dennett, disqualifying qualia, softening up the hard problem, fullness of vacuity, dysfunctional functionalism

Around track 2 of disc 9 of Intuition Pumps , Dennett offers what I would call an argument from vacuity.  He argues that David Chalmers unwittingly plays a magic trick on himself and others by placing a set of issues under the one umbrella called the "hard problem of consciousness." None of these issues is really , in Dennett's opinion, a hard problem.  But in naming them thus, Chalmers (says Dennett) is like a magician who seems to be playing the same card trick over and over again, but is really playing several different ones.  In this analogy, expert magicians watch what they think is the same trick played over and over again.  They find it unusually difficult to determine which trick he is playing because they take these performances as iterations of the same trick when each is  in fact different from the one that came before.  Furthermore, each of the tricks that he plays is actually an easy one, so it is precisely because they are looki...

robot/computers, awareness of causality, holism

For a purportedly cognizant machine to be aware of causality, it would seem (given how it happens with us rational animals) that being aware of its own causal interactions is a necessary condition for its being aware of how causal relations exist in nature.  But to be aware of its own causal interactions, the machine would have to have a sense of its acting as a whole, as an individual, and as being acted upon at a whole.  It would not suffice merely to register information from this or that outside source: there would have to be a sense of the whole acting and being acted upon.   It seems that such awareness requires appropriation and that machines can't do that (at least not in the precise sense that I have discussed in this blog).
