when we first see Phaedra, and when we first hear of her azdos, she is, in Aristotelian terms, an encratic; the effortless virtue which pursues the judgement of zo kafon with pleasure and without a hint of struggle is beyond her, but she does have a judgement of the noble by which she is determined to abide
Cairns argues that Phaedra’s moral psychology maps precisely onto Aristotle’s categories, moving from encratic self-restraint to full akrasia as passionate temptation overcomes her best judgement.
