Before Conway's Game of Life comes his Game of Physics.

Imagine a simple version of the game, with 8x8 squares, each of which is colored either solid white or solid black.  We'll name the squares from the left to the right A through H; and we'll name those from the top to the bottom 1 through 8.

Imagine that at time 1 only A1 is black and the others are white.  At time 2, the very next phase, B2 is the only one that is black, while all of the others are white.  Then C3, then D4, etc.

Given the phi phenomenon,  the onlooker will perceive this change as movement.  But it isn't really.

At this level, we might call this Conway's Game of Physics, for it represents the sort of movement common to living and non-living things.  But it is a rather limited representation.  It's a toy version, and just as a toy gun leaves out that which does the real work, so does this toy version of physics.  Just as someone who plays with a toy compensates for what is lacking in it by using his or her own imagination, so too  one who plays the game of physics perceives movement by supplying (via the phi phenomenon) what is lacking in the representation.

Movement could never be "nothing but" matter that follows the transition rules found in this game.  That is because, movement isn't just something that happens.  Movement (even inertial movement)  is an interplay of some sort.  Rules don't just happen: things interact.

To represent the physical world in this way is to toy with physics: the same is true, a fortiori, of the Game of Life.

***

One who intends to build a board that enacts the transition rules has many different possible causal paths to choose from (electrical switches, mechanical switches, hydraulic switches, etc.).  The underlying causal path is abstracted from by one who plays the game.  To think that these transitions happen without any underlying causal mechanism is to mistake the game for reality.  To look at nature at its most basic level (if there is such a thing) as consisting of nothing but Conway-like rule-governed transitions is likewise to confuse fiction with fact.

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).
