In my Practical Reality I argued that the reasons for which we act are not to be conceived of as psychological states of ourselves, but as real states of the world. The main reason for saying this was that only thus can we make sense of the idea that it is possible to act for a good reason. The good reasons we have for doing this action rather than that one consist mainly of features of the situations in which we find ourselves; they do not consist in our believing certain things about those situations. For instance, the reason for my helping that person is that she is in trouble and I am the only person around. It is not that I believe both that she is in trouble and that I am the only person around. Give that the reason to help is that she is in trouble etc., it must be possible for my reason for helping to be just that, if it is indeed possible for one to act for a good reason. In fact, this sort of thing must be the normal arrangement. The reasons why we act, therefore, that is, our reasons for doing what we do, are not standardly to be conceived as states of ourselves, but as features of our situations.

My topic is the relation between the right and the good. I introduce it by relating some aspects of the debate between various British intuitionists in the first half of the present century. In Principia Ethica G. E. Moore claimed that to be right is to be productive of the greatest good. He wrote ‘This use of “right”, as denoting what is good as a means, whether or not it be also good as an end, is indeed the use to which I shall confine the word’. By the time he wrote his Ethics he seems to have weakened his position, and offers conduciveness to the good not as a definition of ‘right’ but as an account of the one and only property that makes acts right. Even if it be the only right-making property, conduciveness to the good will not be identical with the right-ness that it makes.

Practical Reality is about the relation between reasons for acting in the sense of good reasons, reasons why we should act or reasons in favour of acting, and reasons for acting in the sense of the reasons why someone did what he did—his reasons for acting as he did. This distinction I take to be mere commonsense. It is sometimes expressed by talking about motivating or explanatory reasons as opposed to normative or justifying reasons. Though I do use the motivating/normative distinction, I am wary of any suggestion that I am thereby distinguishing two types of reasons. I think of it rather as distinguishing two contexts in which we use the notion of a reason.

This paper starts by considering an interesting argument of H.A. Prichard’s against the view that to act is to cause a change; the argument is that causing is not an activity. The argument is important because of the recent emergence of an ‘agent-causation’ view according to which actions are the causing of changes by agents. I suggest a way of responding to Prichard’s argument, and then, profiting from one of his own conclusions, turn to consider the relation between neurophysiological changes and the causation of bodily movement by the agent. I make a suggestion about the proper way to understand the relation between the neurophysiological changes, the bodily movements and the action.
