I. the view that reasons cannot be causes. II. the view that the explanatory relevance of psychological states such as beliefs and intentions derives from their content, their explanatory role is not causal and we thus have no good reason to ascribe causal power to them. III. the idea that if the mental supervenes on the physical, then what really explains our actions is the physical properties determining our propositional attitudes, and not those attitudes themselves. IV. the thesis that since there are no laws linking (intentional) mental states to actions, those states cannot be genuine causes of action.

1. Causal explanations depend on our interests, our purposes, and our prior knowledge. ⇒ No uniquely real causal explanation.

There is a difference between someone breaking a glass by accidentally brushing up against it and smashing a glass in a fit of anger. In the first case, the person's cognitive state has little to do with the event, but in the second, the mental state qua anger is quite relevant. How are we to understand this difference? What is the proper way to understand the relation between the mind, the brain, and the resultant behavior? This paper explores the popular "middle ground" reply in which mental phenomena are claimed to be "as real as" other higher level properties. It argues that this solution fails to answer epistemological difficulties surrounding how to chose the appropriate factors in an explanation. A more sophisticated understanding of scientific theorizing and of the relation between ontology and explanation give us a framework in which we can determine when we should refer to mental states as being the causally efficacious agents for some behavior.

The apparent incompatibility of mental states with physical explanations has long been a concern of philosophers of psychology. This incompatibility is thought to arise from the intentionality of mental states. But, Brentano notwithstanding, intentionality is an ordinary feature of higher order behavior patterns in the classical literature of ethology.

causal relevance, a three-place relation between event types, and circumstances, and argue for a logical independence condition on properties standing in the causal relevance relation relative to circumstances. In section 3, I apply these results to show that functionally defined states are not causally relevant to the output or state transitions in terms of which they are defined. In section 4, I extend this result to what that output in turn causes and to intervening mechanisms. In section 5, I examine the implications of this result for functional theories of mental states. In section 6, I distinguish between functional descriptions of properties and functional definitions of properties, and argue the former present no obstacle to mental states being causally relevant to behavior, but that this is so because they do not treat mental states as functional states. In section 7, I examine the nature of explanations that appeal to functional states or properties. section 8 identifies some difficulties that arise in thinking about specifically conscious mental states as functional states. section 9 is a brief conclusion.

Kim argues that we can never have more than one complete and independent explanation for a single event. The existence of both mental and physical explanations for behavior would seem to violate this principle. We can avoid violating it only if we suppose that mental causal relationships supervene on physical causal relationships. I argue that although his solution is attractive in many respects, it will not do as it stands. I propose an alternate understanding of supervenient causation which preserves the advantages of Kim's account while avoiding the problems. My analysis involves appeal to counterfactuals. Any counterfactual analysis must confront the problem that mental states appear to be screened off from causal relevance by physical states. I argue that screening off is not a problem, because cases in which mental states appear to be screened off are cases in which background conditions are not held constant.

subjects mean when they report their mental states it is useful to be guided by a sound grasp of their concepts for mental events. ³ Though this is often ignored in favor of libertarian notions of free will, in which free action is seen as completely undetermined by the subject.

In this paper I distinguish two types of mental causation, called 'higher-level causation' and 'exploitation'. These notions superficially resemble the traditional problematic notions of supervenient causation and downward causation, but they are different in crucial respects. My new distinction is supported by a radically externalist competitor of the so-called Standard View of mental states, i.e. the view that mental states are brain states. I argue that on the Alternative View, the notions of 'higher-level causation' and 'exploitation' can in combination dissolve the problem of mental causation as standardly discussed.
