My goal is to define intending. I defend the view that believing and desiring something are necessary for intending it. They are not sufficient, however, for some things we both expect and want (e.g., the sun to rise tomorrow) are unintendable. Restricting the objects of intention to our own future actions is unwarranted and unhelpful. Rather, the belief involved in intending must be based on the desire in a certain way. En route, I argue that expected but unwanted consequences are not intended, examine the two senses of "desire," distinguish intending from being willing, and relate intending to a variety of other propositional at? titudes.

There is a problem with a very common theory of the nature of action. The problem stems from the fact that causation by practical reasons may be a necessary condition for being an intentional action, but it can’t be a sufficient condition. After all, desires and intentions are caused by practical reasons that rationalize them, but they’re clearly not actions. Even if all actions are events or changes and desires and intentions aren’t, the acquistion of a desire or an intention is an event, but it isn’t always an action. If we can’t understand the nature of action in terms of causation by practical reasons, how should we understand it? The problem only arises if you believe that causation by practical reasons is not sufficient. Maybe the kinds of reasons that rationalize actions are different from the kinds of reasons that rationalize desires and intentions. It’s natural to suppose that reasons for A-ing have to be about A-ing. If the mental state that causes you to turn on the light counts as a reason for turning on the light, then the notion of turning on the light has to figure in the content of the cause. You might believe that turning on the light is a means to an end. Or you might just want to turn on the light. If reasons for A-ing are always about A-ing, but reasons for desiring or intending are only about the objects of desire or intention, if they’re first-order rather than secondorder, then maybe the kinds of reasons that rationalize actions are different from the kinds of..

An autonomous reason for intending to A would be a reason for so intending that is not, and will not be, a reason for A-ing. Some puzzle cases, such as the one that figures in the toxin puzzle, suggest that there can be such reasons for intending, but these cases have special features that cloud the issue. This paper describes cases that more clearly favour the view that we can have practical reasons of this sort. Several objections to this view are considered and rejected. Finally, it is considered whether the existence of such reasons would conflict with an attractive coherence principle linking the rationality of intending with that of acting as intended. The paper concludes with a qualified affirmation of autonomous reasons for intending.

This article is a reply to Jeanne Peijnenburg's argument for retrocausality in "Shaping Your Own Life." Although it is perfectly possible to make sense of the way Peijnenburg deals with the subject of changing the past, there is no need to think this implies retrocausality.

In a recent paper, Jeanne Peijnenburg and David Atkinson [ Studia Logica , 89(3):333-341 (2008)] have challenged the foundationalist rejection of infinitism by giving an example of an infinite, yet explicitly solvable regress of probabilistic justification. So far, however, there has been no criterion for the consistency of infinite probabilistic regresses, and in particular, foundationalists might still question the consistency of the solvable regress proposed by Peijnenburg and Atkinson.

In ‘Infinitism Regained’, Jeanne Peijnenburg argues for a version of infinitism wherein ‘beliefs may be justified by an infinite chain of reasons that can be actually completed’. I argue that Peijnenburg has not successfully argued for this claim, but rather has shown that certain infinite series can be computed.
