“There is no reality except in action.” – Jean-Paul Sartre1
Loosely defined, ethics consists of the set of precepts governing what an individual person should do.2 People typically conceive of ethics as externally directed; for example, how an individual should treat others (equally, justly, compassionately, etc.), or how an individual should act in certain circumstances (courageously, temperately, chastely, etc.). But this view tends to ignore individual capacities such as physical and intellectual abilities. Because humans in a society are chiefly concerned with organizing individual interests and adjudicating competing claims, this other-directed understanding makes sense from a social-political standpoint.
But from a purely philosophical position, this view remains unfounded. Under the basic definition, ethics comprises the qualities a human being should or should not possess and the actions she should or should not perform. Thus, in addition to not wrongly depriving her fellow humans of life, liberty and the pursuit of happiness, a person should be intelligent and fit. By this statement I mean simply that, all things considered, it is better to be more intelligent rather than less intelligent and more physically fit rather than less fit.
First of all, consider Aristotle’s definition of the function of human beings: “activity of the soul in accord with reason or requiring reason.”3 A human being exercises reason. He thinks. But reasoned thought alone does not constitute the nature of humanity. The capacity for reason may distinguish humans from animals, but humans also have bodies. A human who merely thinks of the right things to do is not good; she must also act so as to carry out those reasoned intentions. Hence, human beings are creatures capable of acting in accordance with reason.
In order to be ethical, humans must act, and action requires movement of one’s body. For any movement, three primary questions arise: 1) how much force must the agent apply?, 2) over what distance must the agent apply that force? and 3) how fast must the agent apply that force? We can apply a similar process to judge the ethical status of an individual’s courage. That is, we might ask 1) how much courage is required?, 2) for how long must that courage be displayed? and 3) how readily must the agent undertake the courageous action? The answers to the latter three questions define ethical standards for the character traits and actions necessary to be courageous. And the answers to the former three questions define ethical precepts for human movement. They provide the minimum standards for how a human being should be capable of moving.
1. How much force must an agent apply?
In a previous article, I stated my belief that a functional human being should be able to lift a relatively heavy object off the ground. The benefits of this action to the agent include improved core stability and posterior hip and leg strength. All of these benefits are essential for a healthy spine and optimal physical performance.
Now imagine you find yourself in a burning building. Another person lies unconscious on the ground in front of you. Obviously, you should help this person to safety if you can do so without greatly endangering your own well-being. The question becomes whether or not you are strong enough to lift and move this lifeless body.
To plead weakness out of ignorance, that you never developed the requisite strength because you never expected to find yourself in such a situation seems at first an acceptable, if unfortunate, response. Yet an adult’s claim that he never expected to be in a dangerous situation seems little excuse for his cowardice, just as a capable adult claiming she never expected to be without a calculator seems little excuse for her not knowing multiplication tables. While uncontrollable circumstances like age or physical or mental disability might serve as acceptable excuses, ignorance does not.
However, it seems unreasonable to presume that a trim 120-pound woman should lift a 400-pound sumo wrestler. Likewise, one should not expect an octogenarian or a pre-adolescent child to complete this task. But a healthy adult between the ages of 20 and 35 is certainly capable of lifting his or her own body weight. Therefore, these considerations lead us to the following ethical precept for human movement:
Corollary: A human being should be able to deadlift his or her own body weight.
