Galen is centrally concerned to refute the Stoic view of the hēgemonikon as located in the heart, as against the Platonic-Galenic view of its location in the brain. In the process, while asserting his allegiance to Platonic thought on the soul, it is at least arguable that he adopts a unitary view of the soul and its “command centre” which is conceptually much closer to the Stoic one (on this point see Gill 2010).
