NEW VERSION How the Body Keeps Human Nature in Check

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.'
