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.

The British biologist, philosopher, and psychologist Conwy Lloyd Morgan is widely regarded as one of the founders of comparative psychology. He is especially well known for his eponymous canon, which aimed to provide a rule for the interpretation of mind from behavior. Emphasizing the importance of the context in which Morgan was working—one in which casual observations of animal behavior could be found in Nature magazine every week and psychology itself was fighting for scientific legitimacy—I provide an account of Morgan’s (...) vision for the comparative psychologist qua professional psychologist. To this end, I explore the important connection between Morgan and the evolutionary theorist, philosopher, and psychologist Herbert Spencer. It is from Spencer, I contend, that Morgan inherited a number of his key epistemological and methodological concerns about the nascent science of comparative psychology. This extends all the way to the canon, which only works as intended when paired with a Spencerian understanding of mental evolution as a progressive linear sequence. Far from being an incidental residue of a pre-Darwinian time, hierarchy was intentionally built into the very core of Morgan’s scientific comparative psychology. (shrink)
