Mental causation comes in different shapes, but certainly one of the most conspicuous instances of mental causation is intentional action – when we do something because we want to do it. At least, most action theorists and philosophers of mind take it for granted that intentional action is an instance of mental causation, since they assume first that desires are mental and second that doing something because one wants to do it is to be accounted for causally. Yet, these philosophers face a well-known problem: it may happen that our desires cause what is wanted without that being an instance of our intentionally doing what is wanted. Prima facie, what is wrong in these cases is that the causal path leading from desires to actions goes ‘wayward’ instead of taking the right track, apt for intentional action. Hence, action theorists have tried to specify the right tracks of action causation. But since this turned out to be an awfully tricky task, the idea came up that the whole enterprise may have been ill-advised from the beginning. As I shall argue, this suspicion is correct. Although the two assumptions leading to the problem of waywardness are true (if understood in the right way), the idea of causal paths connecting desires with actions is wrong and should be replaced by a quite different picture of the causal role of desires in agency: desires and other intentional attitudes are causal powers which are actualized in intentional agency. This alternative picture not only has the advantage of accounting for the notorious cases of waywardness, it also relieves some doubts concerning the conceivability of a causal influence of desires in a world of material causes. However, I shall confine myself to the problem of waywardness. My contribution has twelve sections. In section 1, I sketch a standard story about the way we influence the world, and I mention two well known problems discussed in the theory of action. Sections 2 and 3 present three cases of wayward causal chains that pose a third problem for the standard picture. I shall go on to discuss mainly two of them, cases of so-called basic versus non-basic waywardness (section 4) . To understand what is wayward in these cases one needs to understand the special function of ‘by’-sentences (section 5) and the causal role of intentional attitudes (sections 6-8). Sections 9-11 explain the idea that intentional attitudes are causal powers of agents. As it turns out, this accounts smoothly for the two prime examples, but leaves unaddressed a third kind of wayward causal chains. Section 12 closes with an attempt to extend the account to those cases, too, thereby connecting human agency with freedom.

So selbstverständlich es klingt, vom Geist, der Psyche oder auch der Seele eines Menschen zu reden, und so vertraut uns wissenschaftliche Disziplinen sind, die sich philosophisch oder empirisch damit beschäftigen, so schwer fällt es, ein einheitliches Merkmale dafür anzugeben, wann etwas ein psychisches Phänomen ist. Viele der potentiellen Merkmale decken eben nur einen Teil des Spektrums dessen ab, was wir gewöhnlich als psychisch bezeichnen würden, und sind damit bestenfalls hinreichende, aber sicher keine notwendigen Bedingungen des Psychischen. Im Mittelpunkt des folgenden Artikels wird dagegen ein Merkmal stehen, von dem feststeht, daß es nicht hinreichend ist, von dem man aber vermuten kann, es sei zumindest notwendig: die Individualität psychischer Phänomene. Die Frage, mit der ich mich beschäftigen werde, ist, ob sich diese Vermutung mit Bezug auf eine Grnppe paradigmatisch psychischer Phänomene aufrecht erhalten läßt, die intentionalen Einstellungen.

The widely agreed view that actions are events faces the problem of how to describe the “branches” in so-called action trees, i.e. actions which are done by doing other actions. Moreover, the view is also inconsistent with the existence of two familiar species of agency: omitting something and letting things happen. In this article, an alternative conception of action is proposed which takes letting happen as the paradigm of agency. Agency should be construed as an explanatory relation between agents and things happening in the world. This relational view of agency can accommodate for all kinds of agency: doing, letting happen, omitting, prohibiting. And it also provides a satisfactory account of the ontological basis of action trees. We should at first say that to do something is to originate or to bring into existence, i.e., really, to cause, some not yet existing state either of ourselves or of someone else, or, again, of some body.
