This lecture introduces the methodology for conducting an ethical analysis of action sequences, focusing on identifying ethical issues, assessing the impact on 'goods at stake', and evaluating the ethical correctness of decisions. It covers topics such as the principles of universality and equality, tools for ethical analysis, and the idea of 'goods at stake'. Students will learn to evaluate actions from an ethico-political perspective, considering the benefits, costs, and impacts on various dimensions of the good. The methodology includes contextualizing the action, analyzing the goods involved, and assessing the ethical defensibility of decisions. Emphasis is placed on responsible action, ethical evaluation, and the global ethical review of actions.
