Positivist Discrimination

“Oh, God,” Dawkins could be heard to mutter as he fumbled for the full title of Darwin’s On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. Dawkins was on Radio 4′s Today programme to promote his discovery-by-Ipsos-MORI that most Christians in this country are not in fact Christian. The poll, commissioned by the Richard Dawkins Foundation for Reason and Science, came to this conclusion partly by establishing that many self-identifying Christians cannot name certain key books of the bible – hence the Rev. Giles Fraser’s on-air counter-challenge, to which Dawkins rose with typically hubristic bluster.

According to the Telegraph – who, in fairness, also called Dr. Fraser “the archetypal 21st-century vicar, as predictably Lefty as he is drearily on-trend” – the episode was an “intellectual savaging”. While that’s somewhat wishful thinking, the Telegraph also argued that:

If you were trying to come up with a definition of misplaced intellectual arrogance, you could not do better than having the planet’s most famous atheist issuing diktats on who does and doesn’t count as a proper Christian.

I have some sympathy with that. The Dawkins road-show is out of touch with its positivist roots.

Auguste Comte, the founder of the movement known as Positivism, wrestled with the science vs. religion question 150 years ago:

The restoration of theology to its original power, supposing such a thing were possible, would have the most degrading influence on the intellect, and, consequently, on the character also; since it would involve the admission that our views of scientific truth were to be strained into accordance with our wishes and our wants. (Auguste Comte, A General View of Positivism. London: Trübner & Co., 1865. p. 19)

Recognising that “supernatural dogmas became inevitably an obstacle to its growth”, Comte urged that reason ought to “mould its conceptions upon observations, more or less accurate, of the external world” (p. 19). In other words, he called for an understanding of the world based solely on what can be observed, eschewing all non-empirical sources of belief. Comte’s aims were essentially political – the aim of the Positivist method, and its envisioned polity, was to put an end to dogmatic debate and ensure social consensus. As Mary Pickering puts it, in her biography of Comte:

By making all ideas rest on the scientific method, which sought certain knowledge through the observation of facts, positivism would be able to establish irrefutable principles acceptable to each member of society. (Mary Pickering, Auguste Comte: An Intellectual Biography, Vol. 1. Cambridge: Cambridge University Press, 2006. p. 4.)

In the Twentieth Century, the polemic against dogmatism was taken up by a new generation. Logical Positivism, a movement originating from a group of scientists and philosophers in the 1920s known as the Vienna Circle, took its inspiration from forebears such as Ernst Mach (who bore the now quaint-sounding title Professor of the History and Theory of Inductive Science at the University of Vienna). Mach’s writing was influential in its segregation of non-scientific activity: “Where neither confirmation nor refutation is possible, science is not concerned.” (Ernst Mach, The Science of Mechanics. Chicago: The Open Court Publishing Co., 1919. p. 490). Where Comte believed that dogmatic belief was irrational because it wasn’t grounded in empirical evidence, the Logical Positivists held that dogmatic belief was nonsense – literally, without meaning – because statements of that belief were not similarly grounded.

We might say that Positivism is right in spirit, in its call to ground all meaningful discourse in empirical evidence. As Comte wrote, “It teaches that while it is for the heart to suggest our problems, it is for the intellect to solve them” (p. 19). But Positivism in its extreme too easily becomes dogma itself, and the arrogance of Positivism – seen in its eagerness to dismiss non-scientific talk as “a word-series empty of logical content”, as A. J. Ayer put it in his “Demonstration of the Impossibility of Metaphysics” (Mind, 1934. p. 336) – lives on in the fervour of so-called “militant” advocates of science, such as Dawkins: “Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence. Faith is belief in spite of, even perhaps because of, the lack of evidence”, he wrote in the Independent in 1992. Contrast this with Pickering’s portrayal of Comte, for example, who “never intended for sociology to be ‘objective’ or purely empirical. Indeed, he felt pure empiricism was as dangerous as mysticism.” (p. 4)

In its 29 October 2011 issue, New Scientist ran a special report – “Science in America: State of a nation” – that questioned the unenlightened attitudes of several prominent US politicians towards science. It argued that to win “the battle for hearts and minds” scientists need to learn how to find the right frames for communication. Science communicators, equally, need to “find frames that work with broad sections of the population.” Dawkins may be the scientist for whom Oxford’s Chair for the Public Understanding of Science was originally created, but his dogmatic frame isn’t working.

Alone in the Dark

Review written for Spring 2012 issue of I, Science magazine.

Blindsight, Peter Watts (Tor, 2006)

In February 2082, 70 years from now, 65,536 objects enter our atmosphere simultaneously, blanket the Earth in a precise latitudinal/longitudinal grid, emit radio signals for just over a minute, then burn up. This is first contact, this is Firefall.

A crew of post-humans – phenotypes extending into machinery both inside and outside the body – led by a vampire – one of a super-intelligent species genetically engineered back into existence – is sent to investigate a comet in the Kuiper Belt. Their ship, the Captain, lets them sleep for five years, waking them instead for a rendezvous with a super-Jovian beyond the Oort cloud.

So far, so Arthur C. Clarke (except for the vampires). But Blindsight is a novel scattershot with ideas, including 18 pages of appendices and 144 real-world citations. “References and remarks, to try and convince you all I’m not crazy”, is how Watts puts it. On vampire biology, for instance: “Since intersecting right angles are virtually nonexistent in nature, natural selection did not weed out the Crucifix Glitch until H. sapiens sapiens developed Euclidean architecture; by then, the trait had become fixed across H. sapiens vampiris via genetic drift, and—suddenly denied access to its prey—the entire subspecies went extinct shortly after the dawn of recorded history.” Its slow-burning narrative also builds to a resolution of the Fermi paradox that involves one of the most disturbing possibilities I have ever come across.

Given that the age and size of the universe ought to make intelligent life a statistical likelihood, Enrico Fermi wondered in the 1950s why there was no evidence of extraterrestrial civilisations. The number of Earth-like exoplanets recently discovered gives Fermi’s observation renewed bite. However, the devastatingly plausible premise of Blindsight is that intelligence need not imply sentience. Non-sentient life could exist, and evolve, and become what we would call – perhaps anthropomorphically – intelligent. The universe may even be filled with it. But it would not think. It would not reflect. It would not reach out to make contact, it would not make civilisations.

“Everyone else is still looking for some reason for self-awareness to exist, some adaptive advantage that it confers”, Watts once said. “And I really, really hope they’re right, but I can’t think of one.” Consciousness is a distraction, it is energy-inefficient, and as New Scientist reported in 2006, conscious decisions are slower: “At some point in our evolution, we started to make decisions consciously, and we’re not very good at it”, Ap Dijksterhuis of the University of Amsterdam is quoted as saying. Consciousness may be an evolutionary dead end.

“We could engineer ourselves back into non-sentience, perhaps”, one of the crew suggests in Blindsight. “But I guess that wouldn’t be much of a win, would it? What’s the difference between being dead, and just not knowing you’re alive?”

It is often said we can feel most alone in a crowd. Looking up at the sky and imagining it teeming with unconscious life, I believe that to be true.
