Preview: Sam Harris on the free will delusion

The atheist author and neuroscientist on why we're not as free as we think.

The Christmas issue of the New Statesman (you can buy a copy here), guest-edited by Richard Dawkins, includes a brilliant essay by the neuroscientist and atheist author Sam Harris on the illusion of free will. Here, for Staggers readers, is a sneak preview.

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.

All of our behaviour can be traced to biological events about which we have no conscious knowledge. In the 1980s the neurophysiologist Benjamin Libet demonstrated that activity in the brain's motor regions can be detected some 300 milliseconds before a person feels that he has decided to move. Another lab recently used functional magnetic resonance imaging data to show that some "conscious" decisions can be predicted up to ten seconds before they enter awareness (long before the preparatory motor activity detected by Libet). Clearly, findings of this kind are difficult to reconcile with the sense that one is the conscious source of one's thoughts and actions.

For better or worse, these truths about human psychology have political implications, because liberals and conservatives are not equally confused about them. Liberals usually understand that every person represents a confluence of forces that he did not will into being - and we can be lucky or very unlucky in this respect. Conservatives, however, have made a religious fetish of individualism.

The problems with ending encryption to fight terrorism

Forcing tech firms to create a "backdoor" to access messages would be a gift to cyber-hackers.

The UK has endured its worst terrorist atrocity since 7 July 2005 and the threat level has been raised to "critical" for the first time in a decade. Though election campaigning has been suspended, the debate over potential new powers has already begun.

Today's Sun reports that the Conservatives will seek to force technology companies to hand over encrypted messages to the police and security services. The new Technical Capability Notices were proposed by Amber Rudd following the Westminster terrorist attack and a month-long consultation closed last week. A Tory minister told the Sun: "We will do this as soon as we can after the election, as long as we get back in. The level of threat clearly proves there is no more time to waste now. The social media companies have been laughing in our faces for too long."

Put that way, the plan sounds reasonable (orders would be approved by the home secretary and a senior judge). But there are irrefutable problems. Encryption means tech firms such as WhatsApp and Apple can't simply "hand over" suspect messages - they can't access them at all. The technology is designed precisely so that conversations are genuinely private (unless a suspect's device is obtained or hacked into). Were companies to create an encryption "backdoor", as the government proposes, they would also create new opportunities for criminals and cyberhackers (as in the case of the recent NHS attack).

Ian Levy, the technical director of the National Cyber Security, told the New Statesman's Will Dunn earlier this year: "Nobody in this organisation or our parent organisation will ever ask for a 'back door' in a large-scale encryption system, because it's dumb."

But there is a more profound problem: once created, a technology cannot be uninvented. Should large tech firms end encryption, terrorists will merely turn to other, lesser-known platforms. The only means of barring UK citizens from using the service would be a Chinese-style "great firewall", cutting Britain off from the rest of the internet. In 2015, before entering the cabinet, Brexit Secretary David Davis warned of ending encryption: "Such a move would have had devastating consequences for all financial transactions and online commerce, not to mention the security of all personal data. Its consequences for the City do not bear thinking about."

Labour's manifesto pledged to "provide our security agencies with the resources and the powers they need to protect our country and keep us all safe." But added: "We will also ensure that such powers do not weaken our individual rights or civil liberties". The Liberal Democrats have vowed to "oppose Conservative attempts to undermine encryption."

But with a large Conservative majority inevitable, according to polls, ministers will be confident of winning parliamentary support for the plan. Only a rebellion led by Davis-esque liberals is likely to stop them.
