Steven Pinker's notion of truth

He describes what it's like for a statement to be true (he says in many more words that a statement is true when it corresponds to reality) and assumes that he's given an account also of what it's like to believe that one's statement is true. They are not the same.

To believe that one's statement is true is, in part, to expect it to be consistent with other truths that one and others also know.  It is to expect that others who have an adequate knowledge of what you claim to know will concur in their judgment because of what they perceive and understand. There is a tacit awareness of the an open-ended duration of time and a community of rational beings that is larger than one's possible experience.

Does a calculator have all that?  Does a computer?

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...
