A theory of everything?

Why you don't have to be a theist to think physics can't explain it all

There was an interesting letter in the TLS last week from the philosopher Thomas Nagel. Nagel was responding to a letter in the previous week's issue from Stephen Fletcher, a member of the chemistry department at Loughborough University. Fletcher had complained that Nagel recommended Stephen C Meyer's Signature in the Cell in the TLS's Books of the Year round-up.

Meyer's book presents what he describes as a "radical and comprehensive new case" for intelligent design, one that apparently reveals "the evidence not merely of individual features of biological complexity but rather of a fundamental constituent of the universe: information". According to Fletcher,

"Intelligent Design" is of course a code phrase to obscure a malicious and absurd thesis; namely, that a supernatural being has interfered in the evolution of life on this planet. If Nagel wishes to take this notion seriously, very well, let him do so. But he should not promote the book to the rest of us using statements that are factually incorrect.

I haven't read Meyer's book, nor am I competent to assess Fletcher's contention that Nagel simply got the science wrong when he wrote, in his gloss of Signature in the Cell, that "Meyer takes up the prior question of how the immensely complex and exquisitely functional chemical structure of DNA, which cannot be explained by natural selection because it makes natural selection possible, could have originated without an intentional cause". In any case, it's the second paragraph of Nagel's letter that caught my eye:

The tone of Fletcher's letter exemplifies the widespread intolerance of any challenge to the dogma that everything in the world must be ultimately explainable by chemistry and physics. There are reasons to doubt this that have nothing to do with theism, beginning with the apparent physical irreducibility of consciousness. Doubts about reductive explanations of the origin of life also do not depend on theism. Since I am not tempted to believe in God, I do not draw Meyer's conclusions, but the problems he poses lend support to the view that physics is not the theory of everything, and that more attention should be given to the possibility of an expanded conception of the natural order.

The idea that atheism somehow entails a sort of materialistic reductionism, according to which all worldly phenomena can be wholly and exhaustively explained in physical terms, is controversial. It certainly requires more argument than people like Fletcher, or Richard Dawkins, for that matter, tend to provide. This is a point that Nagel made in his review of Dawkins's bestselling The God Delusion back in 2006:

The fear of religion leads too many scientifically minded atheists to cling to a defensive, world-flattening reductionism. Dawkins, like many of his contemporaries, is hobbled by the assumption that the only alternative to religion is to insist that the ultimate explanation of everything must lie in particle physics, string theory, or whatever purely extensional laws govern the elements of which the material world is composed . . . We have more than one form of understanding. Different forms of understanding are needed for different kinds of subject matter. The great achievements of physical science do not make it capable of encompassing everything, from mathematics to ethics to the experiences of a living animal. We have no reason to dismiss moral reasoning, introspection, or conceptual analysis as ways of discovering the truth just because they are not physics.

The point is that you don't have to be a theist to think that physics has a tough job accounting for phenomena such as conscious experience. Though if you believed Dawkins and his epigones, philosophers have long since resolved the puzzle of why that soggy lump of grey matter inside our skulls should give rise to anything so extraordinary as consciousness.

Something is missing from the Brexit debate

Inside Westminster, few seem to have noticed or care about the biggest question mark in the Brexit talks. 

What do we know about the government’s Brexit strategy that we didn’t before? Not much, to be honest.

Theresa May has now said explicitly what her red lines on European law and free movement of labour said implicitly: that Britain is leaving the single market. She hasn’t ruled out continuing payments from Britain to Brussels, but she has said that they won’t be “vast”. (Much of the detail of Britain’s final arrangement is going to depend on what exactly “vast” means.)  We know that security co-operation will, as expected, continue after Brexit.

What is new? It’s Theresa May’s threat to the EU27 that Britain will walk away from a bad deal and exit without one that dominates the British newspapers.

“It's May Way or the Highway” quips City AM“No deal is better than a bad deal” is the Telegraph’s splash, “Give us a deal… or we walk” is the Mirror’s. The Guardian opts for “May’s Brexit threat to Europe”,  and “May to EU: give us fair deal or you’ll be crushed” is the Times’ splash.

The Mail decides to turn the jingoism up to 11 with “Steel of the new Iron Lady” and a cartoon of Theresa May on the white cliffs of Dover stamping on an EU flag. No, really.  The FT goes for the more sedate approach: “May eases Brexit fears but warns UK will walk away from 'bad deal’” is their splash.

There’s a lot to unpack here. The government is coming under fire for David Davis’ remark that even if Parliament rejects the Brexit deal, we will leave anyway. But as far as the Article 50 process is concerned, that is how it works. You either take the deal that emerges from the Article 50 process or have a disorderly exit. There is no process within exiting the European Union for a do-over.  

The government’s threat to Brussels makes sense from a negotiating perspective. It helps the United Kingdom get a better deal if the EU is convinced that the government is willing to suffer damage if the deal isn’t to its liking. But the risk is that the damage is seen as so asymmetric – and while the direct risk for the EU27 is bad, the knock-on effects for the UK are worse – that the threat looks like a bad bluff. Although European leaders have welcomed the greater clarity, Michel Barnier, the lead negotiator, has reiterated that their order of priority is to settle the terms of divorce first, agree a transition and move to a wider deal after that, rather than the trade deal with a phased transition that May favours.

That the frontpage of the Irish edition of the Daily Mail says “May is wrong, any deal is better than no deal” should give you an idea of how far the “do what I want or I shoot myself” approach is going to take the UK with the EU27. Even a centre-right newspaper in Britain's closest ally isn't buying that Britain will really walk away from a bad deal. 

Speaking of the Irish papers, there’s a big element to yesterday’s speech that has eluded the British ones: May’s de facto abandonment of the customs union and what that means for the border between the North and the South. “May’s speech indicates Border customs controls likely to return” is the Irish Times’ splash, “Brexit open border plan “an illusion”” is the Irish Independent’s, while “Fears for jobs as ‘hard Brexit’ looms” is the Irish Examiner’s.

There is widespread agreement in Westminster, on both sides of the Irish border and in the European Union that no-one wants a return to the borders of the past. The appetite to find a solution is high on all sides. But as one diplomat reflected to me recently, just because everyone wants to find a solution, doesn’t mean there is one to be found.
