It is natural to think that at root, agents are beings that act. Agents do more than this, however – agents omit to act. Sometimes agents do so intentionally. How should we understand intentional omission? Recent accounts of intentional omission have given causation a central theoretical role. The move is well-motivated. If some form of causalism about intentional omission can successfully exploit similarities between action and omission, it might inherit the broad support causalism about intentional action enjoys. In this paper (...) I consider the prospects for causalism about intentional omission. I examine two recent proposals: one Carolina Sartorio (2009) defends, and one Randolph Clarke (2010a) defends. I argue these versions fail, and for a similar reason. Reflection on the function of intention for agency brings this reason to light, and motivates a novel causalism about intentional omission. On the account I go on to defend necessarily, an agent J intentionally omits to A only if an intention of J’s with relevant content (or the intention’s acquisition) causes in J a disposition not to A. Though the causal work done by intentions to omit differs in some cases from the causal work done by intentions to act, it turns out that causalism about intentional behavior (i.e., about action and omission) is viable.

This article introduces the notion of the directedness of a process, which underlies event causation as well as the persistence of things. Using this notion it investigates what happens in typical cases of active event causation. Causes never necessitate their effects because even non- probabilistic causes can be counteracted.

The glass vase on my desk is fragile. It should be handled with care because it it is likely to shatter or crack if it is knocked, dropped, or otherwise treated roughly. The vase has certain dispositions, for example the disposition to shatter when dropped. But what is this disposition? It seems on the one hand to be a perfectly real property, a genuine respect of similarity common to glass vases, china cups, ancient manuscripts, and anything else fragile. Yet on (...) the other hand my vase's disposition seems mysterious, "ethereal" (as Nelson Goodman (1954) put it) in a way that, say, its size and shape properties are not. For my vase's disposition, it seems, has to do only with its possibly shattering in certain conditions, conditions which I hope will never be realized. In general, it seems that nothing about the actual behavior of an object is ever necessary for it to have the dispositions it has. Many objects differ from each other with respect to their dispositions in virtue of their merely possible behavior, and this is a mysterious way for objects to differ. (shrink)
