 Acceptance of Empedocles’ philosophical program is envisioned as being dependent upon his physicalist doctrine of the mixture of elements. Its adoption by the addressee relies on a constitution that is receptive to truth. Still, one remains capable of growing in wisdom (Sassi 2016). Alternatively, the disciple will increasingly become cognitively corrupted, “blunted”. The philosopher Theophrastus reports that Empedocles attributed individual temperaments to the more or less favorable mixture of the elements within blood, which was responsible for intelligent, slothful, and impetuous individuals (B 86 = D 237).
