Ray Miller says various things which might be construed to support the traditional argument from design. It turns out that it does nothing of the kind, and in fact undermines it (as usual). Of particular interest was the analogy to SETI, and it is here that I have a few comments to add. > P.S.

Well????? > > A. Ray Miller > Univ Illinois This is a particularly easy "challenge". All you have to do is be minimally aware of what SETI is looking for. They are looking for messages that the sender intends to be found. The patterns that are being looked for are the patterns *we ourselves* would send if we were sending a message to the universe at large. Thus, SETI (as far as I know) makes no claim to being able to unambiguously detect "design", since (as far as I know) this isn't possible in general. In particular, a message that has the highest information content most closely resembles noise. A message that is highly recognizable as a message will have redundancy built in, and minimal "framing assumptions", so that it will be noticable in the largest possble set of contexts. There are two key concepts here. The first is that SETI is looking for patterns that can contain information. As pointed out in the posting, this is not a guarantee of artifical or intensional origins, as the example of the Pulsars with the "LGM" hypothesis warns us. The second is that we are looking for messages of a form that *we might send ourselves*. That is, we can recognize a message that has the form of a message we might send, but will have trouble recognizing a message in a format with which we are unfamiliar. Thus, we are guessing at what formats hypothetical ETIs will use, based on our own experience with messages. The second point has an obvious and strong analogy to the discussions about "argument from design". We can recognize *design* if and only if we could (in principle) do the design ourselves. We can recognize *patterns* even when we could or would not have designed things with these patterns. The argument from design normally confuses these two things, pattern and design. To recognize design, the *method of design* must be known to the finder. Thus, it is easy to recognize design in a sandcastle, since we know how it was built, and can see the evidence of shaping using techniques we know or can imagine. We can see design in a painting, since we recognize the paint, and (an expert) can see the technique reflected in the brush strokes. We can see design in a watch or in an airplane and on and on, because we know how they are made. In order to unambiguously see design in life, we would have to be able to make it ourselves. (I was refering to this point when I asked recently for the "mechanism of creation" of life, rather than just a bald statement that it was indeed created.) Now, saying that patterns don't imply design, I'd have to say that patterns don't imply a natural explaination either. However, when an explaination of perceived patterns is available, and competing explainations explain the pattern less convincingly, *then* the patterns can be construed as "evidence" for the most convincing explaination. -- Wayne Throop at Data General, RTP, NC !mcnc!rti-sel!rtp47!throopw
