The problem of the applicability of moral principles is one of the
most significant issues of practical reflection. With Kant's practical
philosophy, the ethical demands of universality and individuality
came to seem incompatible. After reviewing the outlooks
of Apel and Simmel, who both offer paradigmatic answers to the
“rigorism” of the categorical imperative, this article presents the
issue from the perspective of Maliandi's “Convergent Ethics”. It
suggests that Maliandi's recognition of an “a priori of conflictivity”
and of the bi-dimensional character of reason surmounts the
shortages of both Apel's and Simmel's philosophies
