Payne's Plato citation backfires: Plato actually says the heart is subservient to the head/reason

The Plato passage Payne appeals to actually says the heart was placed near the head so it would 'hearken to reason' and be 'subservient to the citadel of reason.' The heart is cooled by the lungs so its passions remain under the head's control. Plato explicitly says the opposite of what Payne claimed — the head (reason) controls, not the heart. Even in Payne's own footnote, the source contradicts his claim.
