This paper traces the intellectual trajectories of the first stand-alone theories of action, understood as both axiologically neutral and quasi-scientific from a methodological point of view. I argue that the rise of action theory of this kind corresponds to a particular moment of dissatisfaction within Western thought, and as such, it tells us far more about the history of philosophy than the subject itself. I conclude by explaining why subsequent failures to provide an acceptable theory of action are not accidental. (...) On the contrary, such failures owe themselves probably to the fact that formulating a theory of action is neither propitious nor useful. Thus, the most valuable lesson we can learn from philosophical desires for a theory of action is that we should take co-action as the starting point in our normative investigations, rather than positing action simpliciter as a problem to solve. That is, we should move away from propounding a theory of action, and instead focus on a paradigm shift, whereby we move away from a representational, towards a co-actional, model of action.

An increasing number of scholars argue that moral judgements are adaptations, i.e., that they have been shaped by natural selection. Is this hypothesis true? In this paper I shall not attempt to answer this important question. Rather, I pursue the more modest aim of pointing out three difficulties that anybody who sets out to determine the adaptedness of moral judgments should be aware of (though some so far have not been aware of). First, the hypothesis that moral judgements are adaptations (...) has been advocated in various different specificities and scopes, and on various different levels. Second, the three kinds of evidence that have most often been appealed to by discussants of this hypothesis require additional arguments. And third, there is significant reasonable disagreement about what moral judgements essentially are. (shrink)
