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.

Most Leave voters back free movement – you just have to explain it

The argument during the referendum was never about free movement, but about immigration in general. 

This week, a piece of YouGov polling flipped on its head a widely held belief about the public’s attitude to immigration in the context of Brexit. The headline question was:

“In negotiating Britain’s departure from the European Union, do you think our government should offer EU citizens the right to travel, work, study or retire in Britain, in exchange for EU countries giving British citizens the same rights?”

Of the respondents, 69 per cent, including 60 per cent of Leave voters, responded that they should.

The poll has been overlooked by the bulk of the press, for whom it contradicts a very basic assumption – that the end of free movement, and the implicit acceptance of the narrative that high net migration had strained services and wages, was an electoral necessity for any party wanting to enter government. In fact, the apparent consensus against free movement after Brexit owes much less to deeply-rooted public opinion, and much more to the abject failure of progressives and mainstream Remain campaigners to make the case for it.

“If you’re explaining, you’re losing,” goes the old maxim of political communications. And this is accurate if you inhabit a world of tight, professional politics and your job is to capture votes using already widely understood concepts and a set of soundbites. So much of conventional political strategy consists of avoiding difficult or complex subjects, like free movement. This is especially the case if the exact meaning of the words requires defining. The job of radical politics is to change the terms of the debate entirely. That almost always means explaining things.

The strategy of Britain Stronger in Europe during the EU referendum campaign was a case in point. It honed down on its key message on economic stability, and refused to engage with the migration debate. As a result, the terms of the debate were set by the right. The argument during the referendum was never about free movement, but about immigration in general. If YouGov’s polling this week is correct, a majority of the British public support free movement – you just have to explain to them what it means.

That distinction between immigration and free movement was pivotal in the referendum. Immigration is a big, amorphous concept, and an influx of people, covering far more than Britain’s relationship with Europe. It makes an excellent scapegoat for the government’s failure to provide housing and public services. It has been so expertly blamed for bringing down wages that this has become received wisdom, despite almost nowhere being true. Free movement, on the other hand, can be understood more easily in terms of rights and security – not just for migrants in the UK, but for British citizens and workers.

As YouGov’s poll question explains, free movement would be a reciprocal agreement between post-Brexit Britain and the EU, enhancing UK citizens’ rights. We would get the right to live and work freely over an entire continent. Even if you might not want to exercise the right yourself, studying abroad might be something you want to preserve for your children. Even if you might not retire to France or Spain, you might well know someone who has, or wants to.

Perhaps most importantly, free movement makes British workers more secure. Migrants will come to the UK regardless of whether or not free movement agreements are in place; without the automatic right to work, many will be forced to work illegally and will become hyper-exploited. Removing migrants’ access to public funds and benefits – a policy which was in the Labour manifesto – would have a similar effect, forcing migrants to take any work they could find.

At present, Labour is in danger of falling into a similar trap to that of the main Remain campaigns in the EU referendum. Its manifesto policy was for an “economy first Brexit”, in other words, compromising on free movement but implying that it might be retained in order to get access to the single market. This fudge undeniably worked. In the longer term, though, basing your case for free movement entirely on what is good for the economy is exactly the mistake made by previous governments. Labour could grasp the nettle: argue from the left for free movement and for a raft of reforms that raise wages, build homes and make collective bargaining and trade unions stronger.

Making the case for free movement sounds like a more radical task than making the case for immigration more generally – and it is. But it is also more achievable, because continued free movement is a clear, viable policy that draws the debate away from controlling net migration and towards transforming the economy so that everyone prospers. Just as with the left’s prospects of electoral success in general, bold ideas will fare better than centrist fudges that give succour to the right’s narratives.
