Lawrence M. Krauss in Scientific American:
Recently, as a result of my most recent book, A Universe from Nothing, I participated in a wide-ranging and in-depth interview for The Atlantic on questions ranging from the nature of nothing to the best way to encourage people to learn about the fascinating new results in cosmology. The interview was based on the transcript of a recorded conversation and was hard hitting (and, from my point of view, the interviewer was impressive in his depth), but my friend Dan Dennett recently wrote to me to say that it has been interpreted (probably because it included some verbal off-the-cuff remarks, rather than carefully crafted written responses) by a number of his colleagues and readers as implying a blanket condemnation of philosophy as a discipline, something I had not intended.
Out of respect for Dan and those whom I may have unjustly offended, and because the relationship between physics and philosophy seems to be an area which has drawn some attention of late, I thought I would take the opportunity to write down, as coherently as possible, my own views on several of these issues, as a physicist and cosmologist. As I should also make clear (and as numerous individuals have not hesitated to comment upon already), I am not a philosopher, nor do I claim to be an expert on philosophy. Because of a lifetime of activity in the field of theoretical physics, ranging from particle physics to general relativity to astrophysics, I do claim however to have some expertise in the impact of philosophy on my own field. In any case, the level of my knowledge, and ignorance, will undoubtedly become clearer in what follows.
