Abstract
This article seeks to highlight two dimensions of ethics. Understood as aconcept that refers, initially, to a mode of being, and also alludes to an “ought to be”. Starting from this, the aim is to establish some basis to discuss the problems deriving from this double dimension of ethics, stemming from certain ancient Greek philosoph- ical ideas, in particular from Aristotle’s ethics and certain statements from modern philosophy, emphasizing some relevant concepts of Kant’s moral theory. Using said arguments, the final purpose is to call attention to the dilemma in ethics.
