A curious formula is used more than once to express this: a character “addresses his own thumos” and in the course of the following speech says, “Yet still, why does the heart within me debate on these things?”
Williams identifies the Homeric formula of addressing one’s own thumos — the grammatical site of dielexato — as an irreducible form of inner deliberation that cannot be reduced to modern voluntarist notions of will.
