I hope that my book, by laying out the opposite side of the argument from the pro-string theory one that has had wide distribution, will allow many people to make up their own minds about this issue. If one has the time and energy, one can look into the evidence for any scientific theory, and decide for oneself on its validity. When I see leading physicists promoting research which doesnвЂ™t seem to have any plausible way of ever leading to the making of falsifiable predictions, I see real dangers for the field, including the danger of not being able to effectively answer the challenge to legitimate science from ID.ДЇundamentally, the most attractive thing about science to me has always been the fact that it doesnвЂ™t rely on faith or on appeals to authority, the way religion does. ThereвЂ™s lots to be said about the landscape, but the kind of вЂњanthropicвЂќ and related research programs that some people are promoting seem to me to cross over the boundaries of what can legitmately be called the scientific method. String theorists are operating within the realm of standard speculative scientific practice, even though I very much disagree with their take on the scientific evidence for the validity of this speculation that has piled up over the last twenty years.Д«ut thinking about string theory and the landscape has convinced me that the scientific method is something a bit more subtle than we sometimes think. Intelligent Designers donвЂ™t even try to make real science out of it, and have an explicitly religious and political agenda they are pushing, whether they admit it or not. I agree with you that string theory and Intelligent Design are two very different stories. IвЂ™d like to remark that the objections to string theory are only one part of the book, although the part that will undoubtedly get all the attention. In any event, I hope that we defenders of the theory can stick to the high road, and welcome this intervention in the discussion of these important ideas. That might be true, but certainly isnвЂ™t the impression I have from talking to string theorists. There is always the danger of misprepresentation of course, and in this case there is an obvious worry - that a spate of stories will appear about how string theory is in trouble, and a house built on sand, and so forth. If people donвЂ™t agree, they should explain the sources of their disagreement rationally.

So IвЂ™m happy to see this side of the argument represented in the popular press, even if I disagree - we shouldnвЂ™t be afraid of the free market of ideas. To people looking in from the outside, I hope an accurate picture comes across: there is a widespread feeling that string theory is the best hope for a quantum theory of gravity, but itвЂ™s not a settled issue, and weвЂ™re working in good faith on moving forward. But itвЂ™s healthy disagreement among professionals working at the edge of what we know and donвЂ™t know - not politically-motivated intervention from people who have no clue, just an agenda, and operate completely apart from the scientific mainstream. When people like Peter (or Lee Smolin) read these tea leaves, they come to a different conclusion than most scientists in the field. This judgement comes from looking at various pieces of information - what we know about gravitation, and quantum mechanics, and particle physics, and the history of ideas in physics, and the mathematical structures underlying gauge theory and general relativity, as well as an intuitive feeling for what principles are most important and what clues most worth pursuing - and deciding which path toward progress is likely to be fruitful. String theory is far and away the leading candidate, but its status as leader is a reflection of the educated judgement of the experts, not any airtight evidence. The fact is, we donвЂ™t know what is the correct theory that unifies particle physics with gravitation. The whole discussion is a nice contrast with the Intelligent Design mess. (Sometimes more than others, but thatвЂ™s a matter of personal opinion.) But his objections are not crazy, and his dislike for the theory is grounded in an informed scientific judgement. I completely disagree with PeterвЂ™s opinions about string theory, and think that his accusations that the Landscape is non-scientific are completely off the mark. Peter Woit, noted blogger and string-theory gadfly, has written a book about his objections to string theory: Not Even Wrong, to be published next year by Jonathan Cape.
