Science increasingly deals with human behavior: biology, neuroscience, genetics, psychology, evolutionary theory, and ethology all bring new insights into our actions and uncover new facts about our agency. However, what is the philosophical significance of their findings? The answer to this question varies according to one’s background philosophical views. On the one hand, the dominant empiricist view contends that the sciences can in principle tell us everything there is to know about human agency. On the other hand, there are other non-empiricist views – such as Kantian or Aristotelian perspectives – which hold that although science can contribute to our understanding of agency, agency itself cannot be reduced to mere scientific facts. This collection of original essays brings together a number of experts from different philosophical fields (history of philosophy, philosophy of action, ethics, and philosophy of science) to discuss how recent scientific developments about human behavior may be interpreted by, and may be relevant for, non-empiricist conceptions of agency. Contributors share the project of reconciling the scientific and the manifest images of the world in order to reach a stereoscopic vision of reality, with the conviction that philosophy is an attempt to establish coherence among our beliefs, while taking, at least prima facie, all the aspects of our experience at face value.
