 The second group of major opponents of Platonism were the Stoics. The Enneads are filled with anti-Stoic polemics. These polemics focus principally on Stoic materialism, which Plotinus finds to be incapable of articulating an ontology which includes everything in the universe. More important, Stoic materialism is unable to provide explanatory adequacy even in the realm in which the Stoics felt most confident, namely, the physical universe. For example, the Stoics, owing to their materialism, could not explain consciousness or intentionality, neither of which are plausibly accounted for in materialistic terms. According to Plotinus, the Stoics were also unable to give a justification for their ethical position – not in itself too far distant from Plato’s – since their exhortations to the rational life could not coherently explain how one body (the empirical self) was supposed to identify with another body (the ideal rational agent).
