geometry, spheres, circles, boundless, infinite, time

A speaker in an audiobook on geometry (I forget the title and author) mentioned that circles and spheres are boundless but not infinite.  Well, yes.

And no.  For to think of the circle as boundless, one must imagine everlasting duration: one must think of what it would be like to go around and around and around again, etc.

In this context, at least, boundlessness is a function of infinity.

Geometry is not about the timeless: it's about what is (purportedly, seemingly, truly--take your pick) everlasting.

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 ...

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...
