Jeremy Bentham’s Auto-Icon at University College London, photo 2003 by Michael Reeve

Jeremy Bentham, the great English moral and legal philosopher born on February 15, 1748, was a very strange man. A brilliant one, but strange nonetheless. He was a precocious child and advanced in his studies very early, finding Westminster and Queen’s College at Oxford too easy and therefore rather boring. He was trained as a lawyer but decided not to practice law after hearing William Blackstone’s lectures. Blackstone’s treatise Commentaries on the Laws of England is still considered one of the most authoritative and foundational works on English law, so for a guy to consider them so flawed that he’d want to give up his career seems a bit… well, presumptuous. But he demonstrated his own great intellectual capacities through his lifetime of prolific writing, mostly on legal theory, moral philosophy, and social reform. In the end, he earned the right to a certain degree of arrogance.

Bentham is generally considered the father of utilitarianism, the moral philosophy which judges anything that can be judged as right or wrong, good or evil, according to how conducive it is to ‘the greatest happiness of the greatest number.’ Utilitarianism, then, is a type of consequentialism, which holds that a thing is right or wrong based on its consequent harms or benefits. Bentham did not invent the principles of utilitarianism; he discovered them in the writings of Cesare Beccaria (who authored the ‘greatest happiness’ axiom), David Hume, Claude Helvétius, and Joseph Priestley. But he spent a lifetime synthesizing these principles into a cohesive, fleshed-out moral philosophy founded on utility, whether a law or action increases or decreases pleasure or happiness. This principle can seem too subjective to apply to matters of law or public policy; after all, what makes one happy can make another less so, and how can we determine whether the happiness of one is greater, or more important, than the happiness of another? Bentham, careful and systematic in his approach to this as he was to everything else, devised his ‘Felicific Calculus’ to solve this problem. Bentham believed that pleasure, a natural phenomenon like everything else in the world, was likewise quantifiable. He hoped his method of assigning unitary measurements to pleasure, then determining their relative values through mathematics, was a way to make his moral philosophy practicable, conducive to real social reform.

To many, the idea that pleasure and happiness could be reduced to mathematical formulas seems very strange; some think he may have had Asperger’s syndrome or another cognitive feature that caused Bentham to view emotion with such scientific detachment. But as socially awkward as he and his ideas often were, his utilitarian philosophy led to him to some moral conclusions that we now consider extremely progressive and much more caring than those typical of his times. For example, he was an early proponent of racial equality, women’s rights, and animal rights. As to animal rights, just as for all classes of human beings, considering only the pleasure and pain of some sentient beings and not others when it comes to morals is unscientific and therefore unjustifiably biased. After all, animals, like all human beings, have feelings too, and their feelings are just as important to them as ours are to us. So, a moral system based on feelings must consider all equally important, so that one unit of pig happiness, for example, is just as morally significant as one unit of human happiness. The only correct way to balance them out in matters of morals and public policy is to apply the Felicific Calculus to determine how much pleasure or pain each experience in any given situation.

At the end of his long and productive life, the committed naturalist arranged to have his body publicly dissected, both for scientific inquiry and to provide an example to others; he believed that a perfectly good body should never go to waste and that everyone should donate their body to science. He also arranged to have his head and skeleton preserved, dressed in his clothes and stuffed to look as lifelike as possible, to be displayed in some public place. The preservation of Bentham’s head, with its glass eyes he had purchased some years before, left much to be desired; the expression it ended up with creeped people out. So his Auto-Icon, as he called it, sits today in its glass case at University College, London with a nice lifelike wax head in its place. His real head is safely stored away where students, who had stolen it over the years in a series of pranks, can no longer get to it.
