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.

Want an independent-minded MP? Vote for a career politician

The brutally ambitious are not content to fall in with the crowd. 

“Never having had a ‘real’ job outside of politics”: this is what the majority of respondents told a YouGov poll in 2014 when asked the most undesirable characteristic of the British politician. The result is hardly surprising. Type the words “career politician” into your search engine or raise the topic at a dinner party, and quickly you will be presented with a familiar list of grievances.

One of the fundamental criticisms is that career politicians in parliament are elitists concerned only with furthering their own interests. Their pronounced and self-serving ambition for climbing the ministerial ladder is said to turn them into submissive party-machines, sycophants or yes men and women, leading them to vote loyally with their party in every parliamentary division. But do we actually have evidence for this?

A new in-depth analysis, to be published later this month in the academic journal, Legislative Studies Quarterly, presents a forceful challenge to this conventional wisdom. In fact, I find that career politician MPs in the UK are more likely to rebel against their party than their non-career politician peers. Why?

My study was motivated by the observation that the existing impression of the party loyalty of career politicians is based mostly on anecdotal evidence and speculation. Moreover, a look through the relevant journalistic work, as well as the sparse extant academic literature, reveals that the two main hypotheses on the topic make starkly contradictory claims. By far the most popular — but largely unverified — view is that their exclusively professional reliance on politics renders career politicians more brutally ambitious for frontbench office, which in turn makes them especially subservient to the party leadership.

The opposing, but lesser known expectation is that while career politicians may be particularly eager to reach the frontbenches, “many of them are also much too proud and wilful to be content to serve as mere lobby fodder”, as the late Anthony King, one of the shrewdest analysts of British politics, observed nearly thirty years ago on the basis of more qualitative evidence.

Faced with these opposing but equally plausible prognoses, I assembled biographical data for all the MPs of the three big parties between 2005-15 (more than 850) and analysed all parliamentary votes during this period. I followed the debate’s prevalent view that an exclusive focus on politics (e.g. as a special adviser or an MP’s assistant) or a closely-related field (e.g. full-time trade union official or interest group worker) marks an MP as a careerist. In line with previous estimations, just under 20 per cent of MPs were identified as career politicians. The extensive statistical analysis accounted for additional factors that may influence party loyalty, and largely ruled out systematic differences in ideology between career and non-career politicians, as well as party or term-specific differences as drivers of the effects.

As noted above, I find strong evidence that career politician backbenchers are more likely to rebel. The strength of this effect is considerable. For example, amongst government backbenchers who have never held a ministerial post, a non-career politician is estimated to rebel in only about 20 votes per parliament. By contrast, a career politician dissents more than twice as often — a substantial difference considering the high party unity in Westminster.

This finding reveals a striking paradox between the predominantly negative opinion of career politicians on the one hand, and the electorate's growing demand for more independent-minded MPs on the other. In fact career politicians are the ones who perform best in delivering on this demand. Similarly, the results imply that the oft-cited career-related dependency of career politicians on the party can be overridden (or, at the very least, complemented) by their self-image as active and independent-minded participants in the legislative process. This should attenuate the prevalent concern that a rise in career politicians leads to a weakening of parliament’s role as a scrutinizing body.

Finally, the findings challenge the pervasive argument that a lack of experience in the real world disqualifies an MP from contributing meaningfully to the legislative process. Instead, it appears that a pre-parliamentary focus on politics can, under certain circumstances, boost an MP's normatively desirable willingness to challenge the party and the executive.
