Some 10 years ago I witnessed a clash on BBC Newsnight between the British commentator Peter Hitchens and the American-Canadian actor Matthew Perry on the subject of addiction. Hitchens put forward the view that addiction does not really exist and is instead used as an excuse for hedonistic behaviour. Perry, who had claimed to have struggled from drug and alcohol addiction for many years, naturally disagreed. The sad death of Perry in 2023, later revealed to have occurred due to the effects of ketamine, once again put the issue of addiction at centre stage. It is tempting to dismiss Hitchens as a crank; but there are many who subscribe to his view on addiction. In this blog post I will attempt to debunk his arguments.
Hitchens summarized his views on the subject in a 2017 article entitled ‘The Fantasy of Addiction.’ The crux of his argument is outlined in the following paragraph: “The chief difficulty with the word “addiction” is the idea that it describes a power greater than the will. If it exists in the way we use it and in the way our legal and medical systems assume it exists, then free will has been abolished. I know there are people who think and argue this is so. But this is not one of those things that can be demonstrated by falsifiable experiment. In the end, the idea that humans do not really have free will is a contentious opinion, not an objective fact.” However this last sentence is demonstrably false. As I explained in a previous blog post, the idea that human beings have free will is an illusion.
Hitchens would probably respond to my claim by asking me to back it up experimentally. Unfortunately for him, there is a lot of experimental evidence which reinforces the idea that free will does not exist. A pioneering experiment in this field was conducted by the American neuroscientist Benjamin Libet in the 1980s, in which he asked each subject to choose a random moment to flick their wrist while he measured the associated activity in their brain. Libet found that the unconscious brain activity leading up to the conscious decision by the subject to flick their wrist began approximately half a second before the subject consciously felt that they had decided to move. Libet’s findings suggest that decisions are first made on an unconscious level and only afterward are translated into a ‘conscious decision.’
There are dozens of other studies with similar findings that I won’t go into here. Suffice it to say that Hitchens’ second-to-last sentence above – “… this is not one of those things that can be demonstrated by falsifiable experiment” – is also false. However there is a better riposte that does require any experimental evidence at all, which involves pointing out that the concept of free will, as usually understood (and as understood by Hitchens), is incoherent. It implies that we can think a thought before we have thought it. In the memorable phrase of the Austrian-Swiss physicist Wolfgang Pauli, it’s “not even wrong.” There is no need to falsify the concept free will with experimental evidence as logic alone is enough to tell us that it cannot possibly exist.
Hitchens goes on to argue that by using the word ‘addiction’ we are giving the addict “permission to carry on as before.” This is patently untrue. By using the word ‘addiction’ we are recognizing that the addict is suffering from an illness and needs to seek professional help. Hitchens laments the widespread use of the words ‘addiction’ and ‘addict’, arguing that addiction cannot be real because many ‘addicts’ cease to become ‘addicted’. I find it difficult to argue with this as I’m not really sure what point he’s trying to make. He seems to be getting bogged down in semantics here. Or perhaps he has difficulty understanding that someone can be addicted to something and some point in time, then not addicted to it at a later point in time.
One (slightly) better argument Hitchens makes is that the burden of proof lies with those who posit that there is such a thing as addiction. This is quite correct; but what Hitchens hasn’t noticed is that the evidence that addiction is a real phenomenon is all around us. Millions of people around the world from all walks of life can be observed engaging in self-destructive, compulsive behaviour. There are two possible explanations: either these people are wilfully ruining their lives for the sake of a few minutes or hours of short-term pleasure, or they are suffering from an affliction which is making them act in ways in they wouldn’t dream of acting in otherwise. Hitchens apparently thinks the first explanation is more likely to be correct than the second. Most thinking people would disagree.
