Wittgenstein, math and cooperation

While listening to what Wittgenstein has to say about necessity as it pertains to mathematics, I noted that he is not denying that we encounter constraint or necessity when doing mathematics: he is denying that this constraint comes from something outside the game.  Rather, it is from the game itself.  But what if mathematics is a game we can play with rational beings very different from ourselves?  Can we intuit that all would be constrained as we are?  Even if they are incredibly smarter?  And what about God?  Is math a game we play with God rather than being a kind of activity the we aim at God (or at God's Mind) as a kind of ideal object?

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....
