Abstract

THE PRESENT SITUATION in the philosophy of mind may be roughly summed up in three generalizations. First, Cartesian dualism is no longer widely accepted as a genuine option. For many reasons it is no longer taken seriously by experimental psychologists. Perhaps their best reason is that the dualistic hypothesis can provide no satisfactory explanation of behavior since it would seem to make no sense to ascribe to an immaterial substance an internal structure and activity which could be causally linked to behavior. Among philosophers, A. J. Ayer has expressed a characteristic attitude in his admission that he does not find the hypothesis intelligible. Second, a version of materialism, let us call it physicalism, is now being taken seriously as an alternative to Cartesian dualism. According to this version, while it is admitted that mentalistic discourse may not be logically reducible to physicalistic discourse, nevertheless all true statements about the mind are in fact either statements about the behavior of the human body and its organs or about tendencies to behave. Finally, the concept of action has come to the forefront of discussion, and it is being explored primarily by those who reject Cartesian dualism but find something wrong with physicalism. Here is an attempt to construct an alternative to both views by developing a new kind of dualism, namely a distinction between persons as physical organisms and persons as agents, as beings who can act and who have intentions, motives, reasons, desires, and so forth. According to this view, persons are creatures to whom it is essential that teleological concepts apply, and teleological discourse and modes of explanation are not reducible, either logically or empirically, to physicalistic discourse and modes of explanation. Advocates of the new dualism are just as anxious to deny the existence of a ghost in the machine as are the materialists. But, to state roughly what they are after, it is claimed that there are at least two mutually exclusive language games or conceptual schemes which we use to talk about human beings. They are exclusive not in the sense of being about different entities but in the sense of using methods of explanation and concepts which are contextually incompatible with one another. To understand an agent's actions in terms of his intentions and motives is to rule out in that particular context a causal-physiological explanation. Physicalism ignores or fails to appreciate what is distinctively psychological in human life.
