Animal life, Dodds reminds us, is not unrestricted potency but self-regulation. It has its borders both territorially and in behaviour. In Dionysus, borders join that which we usually believe to be separated by borders… Kerényi says that, wherever Dionysus appears, the 'border' also is manifested. He rules the borderlands of our psychic geography.
Hillman, following Kerényi, argues that Dionysus is the archetypal figure of the border itself — not merely a transgressor of limits but the very power that manifests them and dissolves the oppositions they ordinarily enforce.
