Abstract

In this paper, I comment on Waismann’s view of ‘motivational explanations’ as he develops it in his unfinished, posthumously published essay ‘Will and Motive’. According to a traditional view, when we act, the motive is an internal psychological state of which we can know through introspection, and it triggers or causes the action. Thus the motive causally explains an independent event which is the action. As Waismann sees it, everything here is false. The motive is (1) not an internal psychological state. (2) We do not know it through introspection. (3) It does not trigger an action, and (4) there is no causal explanation in which the motive is the cause and the action the effect. I analyze Waismann’s arguments for these claims and work out his positive view. Waismann draws our attention to two features: the uncertainty and instability of motives, and the fact that they are often ascribed on the basis of the action even when the agent wasn’t aware of them prior to acting. Might this hold only for certain motives: viz. ‘Triebfedern’ (drives), in particular those that are unconscious, but not for motives in the sense of ‘Beweggrund’ (reason, purpose)? If action explanations in the light of an agent’s purposes or reasons are unaffected by Waismann’s arguments for the instability and uncertainty of motives, then perhaps the traditional view would not be false for this kind of explanation: it is not uncertain, or unstable. However, I understand Waismann as trying to show (in particular through his interpretation of Dostojevki’s Raskolnikov) that even if a reason for which a person acts or a purpose is something that the agent is aware of prior to action, we get the same kind of instability and uncertainty that occurs with unconscious motives. Here is why: agents are normally aware of quite a number of reasons for and against acting in a certain way. But for any one of those reasons, they may deny – as Raskolnikov does – that that is the reason for which they did it. It was a reason, all right, and even one that they considered, but not the one for which they acted. Thus the problems of instability and uncertainty that Waismann points out affects motives not only insofar as they are unconscious and mere drives. They affect motives in the sense of ‘Beweggrund’ as well.
