Human actions are a central subject of social sciences. Philosophical research into the nature of actions, no doubt, cannot but have consequences for our understanding of social sciences themselves.This article begins by considering the problem of the individuation of a human action: what is an action and what is the difference between the action and bodily movement (or behavior)? I briefly outline and examine Brodbeck and Weber’s philosophical responses to this question. I then attempt to integrate our understanding of action with Donald Davidson’s view on the causal explanation of human action. The aim of my research is to reveal the nature of human action at the end.
