Guest Post: The Grand Design? Part One

Professor Edgar Andrews reviews The Grand Design by Stephen Hawking and Leonard Mlodinow (Bantam Books, September 2010).

Cosmologist Stephen Hawking sold over nine million copies of his book A Brief History of Time. Now, 22 years later, he has co-authored The Grand Design which immediately hit the No.1 spot in the New York Times best-seller list. But the sequel is so inferior to the prequel in intellectual quality that a reviewer in The Times Saturday Review (London, 11 September 2010) writes: ‘It reads like a stretched magazine article … there is too much padding and too much recycling of long-stale material… I doubt whether The Grand Design would have been published if Hawking’s name were not on the cover’.

So why is the new book a runaway best-seller? Because it claims that science makes God redundant. Let’s take a closer look at the claims advanced in The Grand Design.

Philosophical skulduggery

The introduction asserts that ‘Philosophy is dead’ (p.5) and science alone can provide ‘New answers to the ultimate questions of life’ (the book’s hubristic sub-title). But the authors then produce their own brand of humanistic philosophy, christen it ‘science’ and base their book upon it.

They say; ‘this book is rooted in the concept of scientific determinism which implies … that there are no miracles, or exceptions to the laws of nature’. But ‘scientific determinism’ is simply the philosophical assumption that the laws control all events. I argue precisely the opposite in chapter 11 of my own book Who made God? (WMG in further references).

Again, in chapter 3, They maintain that ‘reality’ is a construct of our minds — implying that there is no such thing as objective reality (Irish philosopher Bishop Berkeley had the same idea in 1710 but he wasn’t widely believed). They conclude that ‘there is no picture- or theory-independent concept of reality’ and propose what they call ‘model dependent realism’ as a ‘frame-work with which to interpret modern science’ (pp. 42-43). Clearly, an interpretive framework for science cannot be science but belongs in a different category altogether, namely, philosophy.

Since the mental models we construct ‘are the only reality we can know … It follows then that a well-constructed model creates a reality of its own’ (p.172). The problem with this, of course, is that it undermines the very concept of reality. Hawking’s ‘reality’ excludes God while my ‘reality’ majors upon God. These two ‘realities’ are mutually exclusive but both (according to Hawking) are equally ‘real’. This is postmodernism by the back door and it is wholly inimical to science, which depends on there being a genuine reality to investigate.


The authors also embrace another philosophy, namely, scientific determinism. ‘Though we feel we can choose what we do, our understanding of the molecular basis of biology shows that biological processes are governed by the laws of physics and chemistry and therefore are as determined as the orbits of the planets’ (pp.31-32). So we are mindless automatons and everything we do or think is predetermined.

The reality is, of course, that biological processes are overwhelmingly ‘governed’ not by physics and chemistry but by structured information, stored on DNA and expressed through the genetic code. It is information which controls the physics and chemistry of the living cell, not the other way round.

Furthermore, if our minds are simply by-products of molecular processes in the brain, then all our thoughts are meaningless including the authors’ own theories. Thinking atheists such as Bertrand Russell and J. B. S. Haldane long ago recognised and admitted this dilemma explicitly (WMG chapter 16) but Hawking and Mlodinow seem oblivious to it.

Chapter 4 is devoted to explaining the ‘many histories’ formulation of quantum theory proposed by Richard Feynman. This is well done except that by ignoring other formulations of quantum theory the authors give the false impression that Feynman’s is the only valid approach. This is tendentious because they need Feynman’s idea as a springboard for their own multiverse hypothesis. To admit that ‘many histories’ is just one of several equally valid formulations of quantum mechanics would weaken their argument considerably.
