How the Body Keeps Human Nature in Check

Posted by Eugene Alper

Philosophers have always treated human nature with suspicion. From Plato's legend of the ring of Gyges to Hobbes, Locke, and Rousseau, the belief has been that human nature is fundamentally bad, and that if people could get away with it, they'd rather steal, rape, rob, and kill.

Because of this, one theory goes, people enter into a social contract. To avoid mutual destruction by their raging selves, they give up some of their freedom in exchange for security. The social contract theory, as one example of political philosophising, sounds reasonable. But is the premise correct? Is human nature really fundamentally bad?

It seems to me that however destructive human nature can be in theory—indeed, if we assume that man has free will, then he is capable of committing anything—in real life, man's own body, its vulnerabilities and frequent needs, forces him to co-operate with others rather than try to destroy them.

In real life, we do not think about this much; rather, we co-operate with others by habit instilled in us from childhood. We are trained to behave decently by our own family. Our parents do not want aggressive and unruly creatures bothering them, so for their own comfort they train us to be nice. And we continue to be so throughout life—and those who are not, as we often find out, may not have had that early socialising experience.

But let us pretend that there was no socialising milieu in one's childhood. Let us pretend that somehow a man did not realise that his mother was his only source of food and comfort, and he did not learn to please her. And let us pretend that it did not occur to him later in life that other people were useful to him too, and somehow he failed to master the skill of ingratiating himself with them in order to obtain what he needed. Let us pretend that, instead, the man was dropped from the sky into the world, not knowing anything at all about how it operated. Even then, it is my argument, he would be forced rather quickly to be nice rather than bellicose.

Dropped into the world, the man would promptly discover that his body needs to be fed every four hours and go to sleep every sixteen. His skin, he would notice, is sensitive to cold, heat, and any contact with sharp, hard, or heavy objects, especially if the contact is made at speed. Even walking barefoot, he would observe, can be painful. He would find that the food his body demands so often is not readily available, and to fight for it with other people and animals a few times a day is painful to the skin. It is also risky to try to steal it, for getting away is difficult with the skin being so sensitive. Every night he would learn how physically complicated it is to find a safe shelter to hide from those he might have angered during the day. With his body getting hurt so easily and tired so quickly, he would calculate that it is more energy-efficient to try to engage others in a peaceful exchange, where he would trade for his food something of value to them: a thing he might have, a service he might perform, even a promise he might fulfill in the future.

Even if he were bigger and stronger than other men around him, he would understand that he could not be big and strong twenty-four hours a day. For some eight hours—a third of each day on this planet—he would be as defenseless as a baby, and need to have someone he could trust next to him. Even the meanest tyrant with the worst human nature could not be mean under these circumstances all the time. The vulnerability of his own body at night and its dependence on non-poisonous food during the day would make him behave decently—at the very least to his closest circle.

This is what the man dropped from the sky would discover: however base and wild he might wish to be, his needy body keeps him in check. And philosophy, as fearful as it is of human nature, should acknowledge that it has an ally. The body is not a millstone to which the wing-flipping free will is oh-so-regrettably shackled, but a sensitive vessel playing a noble role. 'Don't be too cocky,' says the body to the free will trapped inside, 'or we will both get hurt.'

One of the greatest problems of our time is the problem as to how ethics may be incorporated into metaphysics. The problem was first brought to the fore by David Hume, and became acute with Ludwig Wittgenstein, who famously wrote, 'Whereof we cannot speak, we must remain silent.'   He was referring to ethics.  

Yet beyond Hume and Wittgenstein – beyond Plato, Immanuel Kant, George Moore, and many others – beyond ethical naturalism, objectivism, rationalism – beyond all philosophy and all theory – it may be as simple as the human body. 

Imagine, with me, a man (or a woman) who is dropped into this world from the sky – not knowing anything at all.

He would very quickly discover that his body needs to be fed every five hours, and put to sleep every sixteen.  His skin, he would notice, is sensitive to cold, heat, and many kinds of pain.  He would find that food is not readily available – that it is dangerous to have to fight for it with other people and animals.  He would find that it is helpful to cultivate plants and domesticate animals – and counter-productive to wantonly destroy them.

He would find that blankets need to be of a certain size and thickness – being predicted, too, by the size and function of his body.  He would find that door handles need to be mounted at a certain height, and made for fingers such as his.  He would find that his body predicts the dimensions of many things: the size of a soccer ball, the shape of a boat – even the location of a university, or the power of rocket boosters.

He would find that it is troublesome to anger others – and to find a new shelter every night, to evade them.  He would soon guess that it is more energy efficient to get into a peaceful exchange with others, where he could trade for food something of his own – a thing or a service, or even a promise to be fulfilled in future.  He would find that his own body, with its vulnerabilities and frequent needs, force him to cooperate with others rather than destroy them.

He would find that, even if he were the biggest and strongest of all, he could not be big and strong twenty-four hours a day. For some eight hours daily he would be as defenseless as a baby, and would have to have someone trusted next to him not to get hurt. Even the meanest tyrant with the worst kind of human nature could not be bad all the time under these circumstances. The vulnerability of his own body in sleep and its dependence on non-poisonous food would make him be good at least to his closest circle.

In short, personal ethics, social ethics, political ethics, aesthetic values – building codes, agricultural norms, communications networks, and everything under the sun – would be governed by the body in which this man found himself at the start.  And not only that, but whatever his nature may be – whether 'good' or 'bad' – he would find that his needy body kept it under control.

It is not a new idea.  Theologians proposed it many centuries ago – namely, that a person is designed for certain ends – of whom Thomas Aquinas was the pre-eminent proponent.  Yet it may be precisely because it was a theological idea that it did not gain much traction.  The theology – whether true or false – may be set aside, yet the situation of this man remains the same, who fell from the sky.

We make no moral prescriptions here – no judgements, no commands, no commitments.  We simply leave a description of what a man (or a woman) is.  And whatever it may mean that he has a body or a soul, it finally comes down to this: 'Don't be too cocky', says the body, 'or you will get hurt.'
