With all the hand-wringing about whether Stephen Hawking's The Grand Design changes anything — whether "philosophy is dead" and whether M-theory promises to explain the appearance of our universe in strictly physical terms — Sir Roger Penrose, because of his stature and relationship to Hawking, is one of the most interesting commentators, and he is none too impressed. On the September 25th broadcast of Unbelievable?, Alister McGrath is carrying on in his exceedingly unctuous way, describing M-theory as "slightly tentative", merely "a staging post along the long road of science..." With wonderful British politeness, Penrose interrupts:  "I think it's actually stronger than that. What is referred to as M-theory isn't even a theory. It's a collection of ideas, hopes, aspirations. ... I think the book is a bit misleading in that respect. It gives you the impression that here is this new theory which is going to explain everything. It's nothing of the sort. ... I think the book suffers rather more strongly than many. It's not an uncommon thing in popular descriptions of science to latch on to some idea, particularly things to do with string theory, which have absolutely no support from observation. They're just nice ideas that people have tried to explore." On the whole, Penrose is less sanguine about the prospects for a theory of everything in the forseeable future. And so far, a number of Hawking's colleagues seem to agree that The Grand Design is much ado about nothing, even apart from its philosophical infelicities. In his review at The Financial Times, Penrose shares a further concern about the subjectivist turn in Hawking's thinking, illustrated by a, shall we say, atypical conversation in which Hawking proposed that black holes and "white holes" are synonomous. The story underscores the extent to which a layperson like myself is at the mercy of their expertise. I am far from competent to evaluate the merits of such esoteric theoretical physics, to do the math and check the sums. And so, it is incumbent upon the specialists to be forthright about the speculative degree of a given theory. In this case, it looks likely that even with the endorsement of the esteemed Hawking, M-theory, in its current state, is unlikely to put to rest either the teleological argument (in terms of fine-tuning) or the cosmological argument (in its Kalām formulation).
