I need to study this passage in Physics more thoroughly:

It's Book 6, chapter 8. It's almost as if Ari's saying that when a thing is moving, it's not right to say that it's here or there... otherwise, one would be saying that this (moving thing) is at rest. Sorta like the scientific discovery that moving things have a certain indeterminacy re their location. I see a parallel...or the mirage of a parallel.

Of course, the latter discovery may be thought to be more epistemic than ontological. That is, one may object to my spotting of a parallel by saying that modern science has shown something about the limits of a scientist's knowledge of motion rather than having gotten an insight into the nature of motion itself. Again, one may object that just because we can't determine exactly where a moving thing is, doesn't mean it doesn't have a definite "where."

Something to look further into.

I wouldn't say that quantum indeterminacy means that we are fundamentally uncertain about the location of an object, as though it's a limit to the length of a ruler. The real issue is that before measurement, a particle is a smeared out blob, whereas upon measurement, it collapses into a point, and then starts to smear out again.

This brings me to the issue - the way that quantum mechanics understands measurement seems to be another example of an inherent "arrow of time" in nature - a phenomena, like the 2nd law of thermodynamics, which delineates a definite beginning, middle, and end.

Re first comment: Really? They should call them weirdicles instead of particles.
Re second: I don't see the arrow of time in the blob-point-blob pattern. But I do see it w/ entropy. But isn't entropy just a global application of the principle that things seek equilibrium (wait: "seek" hmmmn: teleological: voila!).
The amazing thing about observer dependence in quantum theory is that it might be another way in which striving to deanthropomorphize natural science is futile.

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...

entropy, teleology

Perhaps the best way to understand entropy is to look at it as the tendency of things to arrive at equilibrium.  Many non-living processes head in that direction, but not all.  For an example of an exception, consider the movement of electrons around the nucleus: that movement itself doesn't seem to be heading toward any equilibrium… unless one considers the tendency of atoms to combine into molecules so as to fill the electron shells.  If reductionism is false, then isn't the fact that organisms continually create disequilibrium at one level, while seeking another equilibrium (for example a full stomach) quite relevant?   Of course, entropy as a law is about systems, not individuals…. right?
