¿Se salva el argumento de la facultad pervertida con el principio de totalidad? Una visión desde la ética tomista como disciplina tópica

This paper focuses on the adequacy of using the so-called perverted faculty argument (PFA) within the context of sexual morality. According to this argument, frustrating the reproductive faculty would be immoral. Professors García-Huidobro and Miranda think that this argument can be appropriately used only within the framework of the principle of totality. They argue that an unqualified use of the PFA would lead to the absurdities pointed out by the New Natural Law Theory. In order to see the PFA in a new light we demonstrate the importance of respecting the dialectical or contextual nature of Ethics. Thus, regarding temperance, and especially sexual inclinations, the PFA has a clear normative role. The principle of totality, instead, must be used when considering the problem of the moral limits of medical interventions.
