Causal processes that are technically called deviant or wayward causal chains must be ruled out when analyzing various phenomena, including intentional action, perception, and the operation of causal mechanisms involved in the manifesting of causal powers. Irving Thalberg is incorrect in arguing that this problem does not arise when analyzing intentional action. After criticizing solutions proposed by Christopher Peacocke and David Lewis, I provide a general analysis of non-deviance. In application to intentional action, the account is seen to be preferable to that of Michael H. Robins, and proves to be adequate to rule out what Alfred R. Mele calls cases of tertiary waywardness.

Much recent discussion about the nature of perception has focused on the dispute between the Causal Theory of Perception and the rival Disjunctive View. There are different versions of the Causal Theory (the abbreviation I shall use), but the point upon which they agree is that perception involves a conscious experience which is logically distinct from the particular physical object perceived. 1 On the opposed Disjunctive View, the perceptual experience is held to be inseparable from the object perceived; what is directly present to conscious experience is, literally, part of the physical environment. 2 One prima facie difficulty the Causal Theory appears to face is the problem of deviant causal chains, of providing sufficient conditions for perception; I shall not address this difficulty directly, though some of my concluding remarks will bear on it. My main aim in this paper is to show that, despite the deviant causal chains problem, the Causal Theory is to be preferred to the rival Disjunctive View.

On a causal theory of rational behavior, behavior is just a causal consequence of the reasons an actor has. One of the difficulties with this theory has been the possibility of the "wayward causal chains," according to which reasons can cause the expected output, but in such an unusual way that the output is clearly not intentional. The inability to find a general way of excluding these wayward chains without implicitly appealing to elements incompatible with a pure causal account (like brute acts of will) has been a problem for the causal theory. This essay attempts to find a general solution to the problem. The solution rests on the premise that behavior-producing systems are goal-directed, and that on a purely causal analysis of goal-directedness it can be shown that the wayward chains' resulting in the goal is purely fortuitous because these chains do not subserve the function of the system.

Most contemporary philosophers of action agree on the following claims. Firstly, the possibility of deviant or wayward causal chains poses a serious problem for the standard-causal theory of action. Secondly, we can distinguish between different kinds of deviant causal chains in the theory of action. In particular, we can distinguish between cases of basic and cases of consequential deviance. Thirdly, the problem of consequential deviance admits of a fairly straightforward solution, whereas the possibility of basic deviance constitutes a separate and difficult problem that requires its own solution. I will argue that the problem of basic deviance is no more troublesome than the problem of consequential deviance, as a solution to the former is implicit in the standard solution to the latter.

What is the role of practical thought in determining the intentional action that is performed? Donald Davidson’s influential answer to this question is that thought plays an efficient-causal role: intentional actions are those events that have the correct causal pedigree in the agent's beliefs and desires. But the Causal Theory of Action has always been plagued with the problem of “deviant causal chains,” in which the right action is caused by the right mental state but in the wrong way. This paper addresses an alternative approach to understanding intentional action inspired by G.E.M. Anscombe, interpreting that view as casting practical thought in the role of formal rather than efficient cause of action and thereby avoiding the problem of deviant (efficient) causal chains. Specifically, on the neo-Anscombean view, it is the agent’s “practical knowledge” – non-observational, non-inferential knowledge of what one is doing – that confers the form of intentional action on an event and is the contribution of thought to determining what is intentionally done. This paper argues that the Anscombean view is subject to its own problematic type of deviance: deviant formal causation. What we know non-observationally about what we are doing often includes more than what we intend to be doing; we also know that we are bringing about the foreseen side effects of acting in the intended way. It is argued that the neo-Anscombean view faces difficulty in excluding the expected side effects from the specification of what is intentionally done, whereas the Causal Theory has no such difficulty. Thus, the discussion amounts to an argument in favor of the Causal Theory of Action.

This paper proposes a causal-dispositional account of rule-following as it occurs in reasoning and intentional agency. It defends this view against Kripke’s (1982) objection to dispositional accounts of rule-following, and it proposes a solution to the problem of deviant causal chains. In the first part, I will outline the causal-dispositional approach. In the second part, I will follow Martin and Heil’s (1998) realist response to Kripke’s challenge. I will propose an account that distinguishes between two kinds of rule-conformity and two kinds of rule-following, and I will defend the realist approach against two challenges that have recently been raised by Handfield and Bird (2008). In the third part, I will turn to the problem of deviant causal chains, and I will propose a new solution that is partly based on the realist account of rule-following.

What exactly is reasoning? Like many other philosophers, I shall endorse a broadly causal conception of reasoning. Reasoning is a causal process, in which one mental event (say, one’s accepting the conclusion of a certain argument) is caused by an antecedent mental event (say, one’s considering the premises of the argument). Just like causal accounts of action and causal accounts of perception, causal accounts of reasoning have to confront a version of what has come to be known as the problem of deviant causal chains. In this paper, I shall propose an account of the nature of reasoning, incorporating a solution to the specific version of the deviant causal chains problem that arises for accounts of reasoning. One striking feature of my solution is that it requires that certain normative facts are causally efficacious. It might be thought that this feature will make my account incompatible with any plausibly naturalistic approach to understanding the mind. I shall argue that this is not so: my account of the nature of reasoning is quite compatible with plausible versions of naturalism.
