Preview: The Four Horsemen of New Atheism reunited

Christopher Hitchens, Daniel Dennett, Richard Dawkins and Sam Harris together for the final time in

Christopher Hitchens, Daniel Dennett, Richard Dawkins and Sam Harris together for the final time in the NS.

In the special Christmas issue of the New Statesman, guest-edited by the evolutionary biologist Richard Dawkins and available for purchase here, the four leading members of the New Atheism movement have been brought together for the final time.

The name "Four Horsemen" refers to Richard Dawkins, Christopher Hitchens, Daniel Dennett and Sam Harris and was first used during a 2007 debate in which they discussed their criticisms of religion and advocated critical thinking.

Inside the pages of this New Statesman double issue, Richard Dawkins has contributed an essay, "The tyranny of the discontinuous mind" and written the NS leader column, in which he launches a scathing attack on David Cameron and his government's imposition of religious tradition on society in the form of faith schools. He writes:

Modern society requires and deserves a truly secular state, by which I do not mean state atheism, but state neutrality in all matters pertaining to religion: the recognition that faith is personal and no business of the state.

For the issue, Dawkins also travelled to Texas to conduct an exclusive interview with the late author and journalist Christopher Hitchens. In what turned out to be Hitchens's final interview before his death on 15 December, he and Dawkins discussed topics ranging from religious fundamentalism and US politics, to Tony Blair, abortion and Christmas. At the time, Hitchens said of his legacy:

It may strike some people as being broad but it's possibly at the cost of being a bit shallow. I became a journalist because one didn't have to specialise. I remember once going to an evening with Umberto Eco talking to Susan Sontag and the definition of the word "polymath" came up. Eco said it was his ambition to be a polymath; Sontag challenged him and said the definition of a polymath is someone who's interested in everything and nothing else. I was encouraged in my training to read widely - to flit and sip, as Bertie [Wooster] puts it - and I think I've got good memory retention. I retain what's interesting to me, but I don't have a lot of strategic depth.

A lot of reviewers have said, to the point of embarrassing me, that I'm in the class of Edmund Wilson or even George Orwell. It really does remind me that I'm not. But it's something to at least have had the comparison made - it's better than I expected when I started.

The American author, neuroscientist and atheist Sam Harris has offered an essay on the illusion of free will (further extracts from which can be found here):

Even though we can find no room for it in the causal order, the notion of free will is still accorded a remarkable deference in the scientific and philosophical literature, even by those who believe that the mind is entirely dependent on the workings of the brain. However, the truth is that free will doesn't even correspond to any subjective fact about us, for introspection soon grows as hostile to the idea as the equations of physics have. Apparent acts of volition merely arise, spontaneously (whether caused, uncaused or probabilistically inclined, it makes no difference), and cannot be traced to a point of origin in the stream of consciousness. A moment or two of serious self-scrutiny, and you might observe that you decide the next thought you think no more than you decide the next thought I write.

And finally, the American philosopher and cognitive scientist Daniel Dennett has written "The social cell", an exclusive NS Christmas Essay which poses and attempts to answer the question: What do debutante balls, the Japanese tea ceremony, Ponzi schemes and doubting clergy all have in common?:

We need to look dispassionately at possibilities that can illuminate - and might eventually eliminate - some serious sources of suffering in the world. Once we appreciate the necessity of metabolism, reproduction and protective membranes for social cells as much as for protein-based cells, we can see more clearly the effects that novel environmental factors are likely to have on the prospects for these phenomena . . . Societies are complex in more ways than colonies of bacteria are. What does shine through is a principle of good design. Darwin showed us that the secret of life is the differential reproduction of effective designs for fending off dissolution. When we approach social phenomena with the same spirit of reverse engineering, we find a bounty of insights that can help us plan intelligently for the future.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
