This article reviews the task of ethical reasoning (or of norms or moral valuation), the basic problem of the level of reflection typically labeled as "normative." The article shows different attitudes from which to seek to clarify "the why" of moral phenomenon, following a classification based on the distinction between empiricism (related to consequentialism) and a priorism (at some point linked with deontologism). Also, insufficiencies and weaknesses of both statements are highlighted, projecting its usefulness for a future task of statements of reason in the context of bioethics.
