Dans le cadre des ateliers du GRIN, Ulf Hlobil (Concordia University) offrira une présentation intitulée “On Weighing Reasons with Defeaters”.
According to the Reasoning View about normative reasons, R is a normative reason to φ just in case R can figure as a premise in good reasoning that results in φ-ing. As is widely recognized among advocates of the Reasoning View (e.g. Setiya, Way, Asarnow), the most important challenge for the Reasoning View is to give an account of how reasons can be outweighed. It is also widely recognized that this is best done by appeal to the defeasibility of reasoning. After introducing the Reasoning View, I start by criticizing different accounts of weights in terms of defeasibility. I then offer my own account of the weights in terms of defeasibility. A crucial feature of the account is that it distinguishes premises of practical reasoning from background attitudes. Along the way, I introduce notions of enablers, obligations, and virtuous action. I end by suggesting that the “objective ought” and “objective reasons” are idealizations, and that the “subjective ought” and “subjective reasons” are primary.
