Epitome of the Complete Works of Galen

so Memory is present to Reason, preserving as faithfully as possible all things that occur to it, if they are of any importance; and when the occasion demands, it suddenly provides them, as if from a certain storehouse. Princes are accustomed to have, in both peace and war, certain sworn soldiers, both to repel external injuries and to keep the minds of the citizens in obedience and faith. Surely, that Divine Architect of ours has joined to Reason the irascible power, called by Plato thymoeide spirited/passionate, so that if Reason were ever undeservedly harassed by someone, this power, becoming inflamed immediately, might bring helping hands to it and repel all force. Nature has placed this very faculty by which we become angry in the heart, so that it might be positioned exquisitely between Reason and the Desires, which are situated in the liver and, making various excursions from there, are exceedingly seditious and cause a great deal of trouble for Reason. Therefore, between them and the irascible power, Nature has also placed a very firm rampart, namely the diaphragm, lest those desires might oppress an unprepared anger, and rising up later against Reason, capture its citadel.
