Can Kant tell us what to do? Intentions, dilemmas, and the long journey towards moral perfection
Revista de Estudios Kantianos, 2023 The “received view” on Kantian ethics holds that perfect duties enjoy absolute priority over imperfect duties. More recently, several Kantian scholars have reassessed this situation, arguing that imperfect duties may remain binding even if they imply ...
