Irascible, a term from scholastic philosophy. It is certain that all the movements of our souls can be reduced to desire and aversion, to the desire that brings us closer, and the aversion that pushes us away. The scholastics grouped these two movements under the name of appetite , and divided appetite into irascible and concupiscible. They related the former to anger, audacity, fear, hope, despair and the rest of this category, and the latter to voluptuousness, joy, desire, love, etc.... Plato completed the system of the mind and spirit, by adding a reasoning part to these two branches, which was the only one to survive the destruction of the body: the only immortal part. The other two parts perished with the body. He located the irascible quality in the heart, the concupiscible part in the liver, and the reasonable part in the head. It is certainly true that our passions, and even more generally our actions, can all be attributed to particular organs. But there is only one substance. It is inconceivable that one part should pass away and the others remain. In any event, this way of seeing shows clearly enough that Socrates and Plato had no idea about spirituality.
