Basil Fawlty, British television's hotelier from hell created by the immortal John Cleese, was at the end of his tether when his car broke down and wouldn't start. He gave it fair warning, counted to three, gave it one more chance, and then acted. "Right! I warned you. You've had this coming to you!" He got out of the car, seized a tree branch and set about thrashing the car within an inch of its life. Of course we laugh at his irrationality. Instead of beating the car, we would investigate the problem. Is the carburettor flooded? Are the sparking plugs or distributor points damp? Has it simply run out of gas? Why do we not react in the same way to a defective man: a murderer, say, or a rapist? Why don't we laugh at a judge who punishes a criminal, just as heartily as we laugh at Basil Fawlty? Or at King Xerxes who, in 480 BC, sentenced the rough sea to 300 lashes for wrecking his bridge of ships? Isn't the murderer or the rapist just a machine with a defective component? Or a defective upbringing? Defective education? Defective genes?
Concepts like blame and responsibility are bandied about freely where human wrongdoers are concerned. When a child robs an old lady, should we blame the child himself or his parents? Or his school? Negligent social workers? In a court of law, feeble-mindedness is an accepted defence, as is insanity. Diminished responsibility is argued by the defence lawyer, who may also try to absolve his client of blame by pointing to his unhappy childhood, abuse by his father, or even unpropitious genes (not, so far as I am aware, unpropitious planetary conjunctions, though it wouldn't surprise me).
But doesn't a truly scientific, mechanistic view of the nervous system make nonsense of the very idea of responsibility, whether diminished or not? Any crime, however heinous, is in principle to be blamed on antecedent conditions acting through the accused's physiology, heredity and environment. Don't judicial hearings to decide questions of blame or diminished responsibility make as little sense for a faulty man as for a Fawlty car?
