Stoic self-consciousness

I investigate Stoic accounts of the structure and function of self-consciousness, specifically in connection with the Stoic notion of Oikeiosis. After reviewing the tortured history of attempts to translate this ancient notion into modern terms, I set out to determine its content by identifying its inferential role in Stoic moral psychology. I then provide a reconstruction of the Stoic claim that Oikeiosis is or involves a form of self-consciousness (Chrysippus), self-sentiment (Seneca), or synæsthesia (Hierocles). I show how the Stoic conception of self-consciousness differs fundamentally from modern accounts of selfconsciousness as a form of psychic self-presence or epistemic self-certainty, and I exhibit the limitations of Long’s treatment of Stoic self-consciousness as proprioception. Finally, I offer a reconstruction of the Stoic claim that self-consciousness figures as a condition on the possibility of perception and desire, providing a form of normative orientation essential for intentional determinacy.
