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.

Staying in the EU would make it easier to tackle concerns about immigration, not less

Brexit is not only unlikely to deliver the control people want, it may actually undermine people’s faith in the system even further.

As Theresa May prepares to set out her latest plan for Brexit in Florence on Friday, those on all sides of the debate will wait to see if there are answers to fundamental questions about Britain’s future outside of the EU. Principle among those is how the UK immigration system will work. How can we respond to Leave voters’ concerns, while at the same time ensuring our economy isn’t badly damaged?

We must challenge the basic premise of the Vote Leave campaign: that dealing with public’s concern about immigration means we have to leave the EU and Single Market.

In fact the opposite is true. Our study into the options available to the UK shows that we are more likely to be able to restore faith in the system by staying within Europe and reforming free movement, than by leaving.

First, there are ways to exercise greater control over EU migration without needing to change the rules. It is not true that the current system of free movement is "unconditional", as recently claimed in a leaked Home Office paper. In fact, there is already considerable scope under existing EU rules to limit free movement.

EU rules state that in order to be given a right to reside, EU migrants must be able to demonstrate proof that they are either working, actively seeking work, or self-sufficient, otherwise they can be proactively removed after three months.

But unlike other continental systems, the UK has chosen not to operate a worker registration system for EU nationals and thus has no way of tracking where they are or what they’re doing. This could be changed tomorrow, if the government were so minded.

Other reforms being discussed at the highest levels within Europe would help deal with the sense that those coming to the UK drive down wages and conditions. The UK could make common cause with President Macron in France, who is pushing for reform of the so-called "Posted Workers Directive", so that companies seeking to bring in workers from abroad have to pay those workers at the same rate as local staff. It could also follow the advice of the TUC and implement domestic reforms of our labour market to prevent exploitation and undercutting.

Instead, the UK government has chosen to oppose reform of the Posted Workers Directive and made it clear that it has no interest in labour market reform.

Second, achieving more substantive change to free movement rules is not as implausible as often portrayed. Specifically, allowing member states to enact safeguards to slow the pace of change in local communities is not unrealistic. While the principle of free movement is a cornerstone of the European project, how it is applied in practice has evolved. And given that other countries, such as France, have expressed concern and called for reform, it is likely to evolve further.

The reforms to free movement negotiated by David Cameron in 2016 illustrate that the EU Commission can be realistic. Cameron’s agreement (which focused primarily on benefits) also provides an important legal and political precedent, with the Commission having agreed to introduce "safeguards" to respond to "situations of inflow of workers from other Member States of an exceptional magnitude over an extended period of time".

Similar precedents can be found within a number of other EU agreements, including the Acts of Accession of new Member States, the European Economic Area (EEA) Agreement and the Treaty on the Functioning of the European Union (TFEU). The UK should seek a strengthened version of Cameron’s "emergency brake", which could be activated in the event of "exceptional inflows" from within the EU. We are not the first to argue this.

Of course some will say that it is unrealistic to expect the UK to be able to get more than Cameron achieved in 2016. But put yourself if in the shoes of the EU. If you believe in a project and want it to succeed, moral imperative is balanced with realism and it hardly needs pointing out that the political context has radically shifted since Cameron’s negotiation.

In contrast, a "hard Brexit" will not deliver the "control of our borders" that Brexiteers have promised. As our report makes clear, the hospitality, food, manufacturing and social care sectors heavily depend on EU workers. Given current employment rates, this means huge labour shortages.

These shortages cannot be wished away with vague assertions about "rejoining the world" by the ultra free-market Brexiteers. This is about looking after our elderly and putting food on our tables. If the UK leaves in April 2019, it is likely that the government will continue to want most categories of EU migration to continue. And whatever controls are introduced post-Brexit are unlikely to be enforced at the border (doing so would cause havoc, given our continued commitment to visa-free travel).  Instead we would be likely to see an upsurge in illegal migration from within the EU, with people arriving at the border as "visitors" but then staying on to seek work. This is likely to worsen problems around integration, whereby migrants come and go in large numbers, without putting down roots.

We can do this a different way. The important issues that most drive public concern about EU migration - lack of control, undercutting, pace of change - can be dealt with either within current rules or by seeking reform within the EU.

The harsh truth is that Brexit is not only unlikely to deliver the control people want, it may actually undermine people’s faith in the system even further.

Some will say that the entire line of argument contained here is dangerous, since it risks playing into an anti-immigrant narrative, rather than emphasising migration’s benefits. This is an argument for the ivory tower, not the real world.

There is a world of difference between pandering to prejudice and acknowledging that whilst EU migration has brought economic benefits to the UK, it has also created pressures, for example, relating to population churn within local communities.

The best way to secure public consent for free movement, in particular, and immigration in general, is to be clear about where those pressures manifest and find ways of dealing with them, consistent with keeping the UK within the EU.

This is neither an attempt at triangulation nor impractical idealism. It’s about making sure we understand the consequences of one of the biggest decisions this country has ever taken, and considering a different course.
