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.

Dembski's "specified compexity" semiotics and teleology (both ad intra and ad extra)

Integral to Dembski's idea of specified complexity (SC) is the notion that something extrinsic to evolution is the source of the specification in how it develops. He compares SC to the message sent by space aliens in the movie "Contact." In that movie, earthbound scientists determine that radio waves originating in from somewhere in our galaxy are actually a signal being sent by space aliens. The scientists determine that these waves are a signal is the fact that they indicate prime numbers in a way that a random occurrence would not. What is interesting to me is the fact that Dembski relies upon an analogy with a sign rather than a machine. Like a machine, signs are produced by an intelligent being for the sake of something beyond themselves. Machines, if you will, have a meaning. Signs, if you will, produce knowledge. But the meaning/knowledge is in both cases something other than the machine/sign itself. Both signs and machines are purposeful or teleological...

particular/universal event/rule

While listening to a recorded lecture on Quine's Two Dogmas of Empiricism, it occurred to me that every rule is in a way, a fact about the world. Think about baseball: from the p.o.v. of an individual player, a baseball rule is not a thing but a guide for acting and interpreting the actions of others.  But this rule, like the action it guides, is part of a concrete individual --i.e., part of an institution that has come into existence at a particular place and time, has endured and  may eventually go out of existence.  The baseball rule, as a feature of that individual, is likewise individual.  The term "baseball rule," on the one hand, links us to a unique cultural event; it can, on the other hand, name a certain type of being.  In this way, it transgresses the boundary between proper and common noun. If there were no such overlap, then we might be tempted to divide our ontology between a bunch of facts "out there" and a bunch of common nouns "in here....
