Prohairesis as a possible instance of metaphysical implication in Aristotle's ethics

Ancient and medieval interpreters of Aristotle regarded his ethics and metaphysics as somehow connected. This nexus has been strictly denied by contemporary scholars. A deepened analysis of the core of human action, could help us to recover, under a new perspective, the conviction of the Ancients. This core is prohairesis ("something chosen before other things"). Prohairesis discloses a proper mark (idion) of man: man is that sort of being which acts for the sake of something. In so doing he is a cause. Therefore, considering prohairesis has much to do with considering how man is inserted in the order of the causes, that is to ask about the place he takes in reality as a whole.
