From the Naturalism Workshop, Part I

Around the table-2

Massimo Pigliucci reports on the Naturalism Workshop conceived of by Sean Carroll, over at Rationally Speaking:

During the roundtable introductions, Dawkins (as well as the rest of us) was asked what he would be willing to change his mind about; he said he couldn’t conceive of a sensible alternative to naturalism. Rosenberg, interestingly, brought up the (hypothetical) example of finding God’s signature in a DNA molecule (just like Craig Venter has actually done). Dawkins admitted that that would do it, though immediately raised the more likely possibility that that would be a practical joke played by a superhuman — but not supernatural — intelligence. Coyne then commented that there is no sensible distinction between superhuman and supernatural, in a nod to Clarke’s third law.

There appeared to be some interesting differences within the group. For instance, Rosenberg clearly has no problem with a straightforward functionalist computational theory of the mind; DeDeo accepts it, but feels uncomfortable about it; and Deacon outright rejects it, without embracing any kind of mystical woo. Steven Weinberg asked the question of whether — if a strong version of artificial intelligence is possible — it follows that we should be nice to computers.

The first actual session was about the nature of reality, with an introduction by Alex Rosenberg. His position is self-professedly scientistic, reductionist and nihilist, as presented in his The Atheist’s Guide to Reality. (Rationally Speaking published a critical review of that book, penned by Michael Ruse.) Alex thinks that complex phenomena — including of course consciousness, free will, etc. — are not just compatible with, but determined by and reducible to, the fundamental level of physics. (Except, of course, that there appears not to be any such thing as the fundamental level, at least not in terms of micro-things and micro-bangings.)
