“Is-Ought Question” and Aristotelian-Thomistic Metaphysics
Meta–ethics distinguishes from the field of ethics in focusing research on what makes ethics possible qua talis, rather than direclty dealing with the thorough foundation of specific ethical theories or, like in applied ethics, with some specific ethical issues.
Indeed my deep interest in metaethics is due to the relevance that the central question about God’s existence cannot be denied to play in order to establish ethics’ true foundation and essence. In particular — against the post–kantian ideological fashon that affirms an always more radical independence of ethics from ontology and metaphysics, a tendency further enhanced by what I hold to be the wrong interpretations of the so called “Is-Ought Question”— the main point of my research is that everything changes in ethics if God exists or if does not exist.
The question concerning the foundation of ethics is surely complex, but I think to have at least delineated the fundamental aspects of the thematic, by having enhanced the scope and conclusions of what I wrote in a long paper back in 2003 (in Italian). Here I will just hint at the present status of the ongoing project through the two following diagrams, within which the basic contents of the 2003 article and the new theoretical developements have been integrated.
