Here Galen again draws on Stoic terminology, and talks of the “total mixture” (krasis di’ holōn). In Stoic theory, this “total mixture” involves the notion that the two bodies mixed in this particular way co-inhabit one space. Galen does not commit himself on the precise metaphysical description, but seems to prefer the formulation that the qualities (poiotētes) undergo total mixture while the bodies do not.
