The radical breakthrough that stoic ethics operates in the unfolding
of Hellenistic philosophy can only be fully grasped against
the background of the school's endeavour to develop a nonsubstantialist
metaphysics that transcends the limits imposed by
Aristotle. Thus, the aim of this paper is to bring out to light the
monistic cosmological foundations on which any interpretation of
stoic ethics must be constructed, articulated around the concepts of
immanence and necessity.
