Ordinary moral thought often commits what social psychologists call 'the fundamental attribution error '. This is the error of ignoring situational factors and overconfidently assuming that distinctive behaviour or patterns of behaviour are due to an agent's distinctive character traits. In fact, there is no evidence that people have character traits in the relevant sense. Since attribution of character traits leads to much evil, we should try to educate ourselves and others to stop doing it.

This paper argues that the medical conception of health as absence of disease is a value-free theoretical notion. Its main elements are biological function and statistical normality, in contrast to various other ideas prominent in the literature on health. Apart from universal environmental injuries, diseases are internal states that depress a functional ability below species-typical levels. Health as freedom from disease is then statistical normality of function, i.e., the ability to perform all typical physiological functions with at least typical efficiency. (...) This conception of health is as value-free as statements of biological function. The view that health is essentially value-laden, held by most writers on the topic, seems to have one of two sources: an assumption that health judgments must be practical judgments about the treatment of patients, or a commitment to "positive" health beyond the absence of disease. I suggest that the assumption is mistaken, the commitment possibly misdescribed. (shrink)

This paper examines the implications of certain social psychological experiments for moral theory—specifically, for virtue theory. Gilbert Harman and John Doris have recently argued that the empirical evidence offered by ‘situationism’ demonstrates that there is no such thing as a character trait. I dispute this conclusion. My discussion focuses on the proper interpretation of the experimental data—the data themselves I grant for the sake of argument. I develop three criticisms of the anti-trait position. Of these, the central criticism concerns three (...) respects in which the experimental situations employed to test someone's character trait are inadequate to the task. First, they do not take account of the subject's own construal of the situation. Second, they include behaviour that is only marginally relevant to the trait in question. Third, they disregard the normative character of the responses in which virtue theory is interested. Given these inadequacies in situationism's operationalized conception of a ‘character trait’, I argue that situationism does not really address the proposition that people have ‘character traits’, properly understood. A fortiori, the social psychological evidence does not refute that proposition. I also adduce some limited experimental evidence in favour of character traits and distil two lessons we can nevertheless learn from situationism. (shrink)

My chief aim is to explain how someone can act freely against her own best judgment. But I also have a second aim: to defend a conception of practical rationality according to which someone cannot do something freely if she believes it would be better to do something else. These aims may appear incompatible. But I argue that practical reason has the capacity to undermine itself in such a way that it produces reasons for behaving irrationally. Weakness of will is (...) possible because it is possible to conclude that one has sufficient reason to reject the verdicts of one's own reason. (shrink)
