Enneads I.1: The Organism and the Self
Refutation of the (James-lange) Theory of Emotions
We shall later on consider the organized body; here we must find how the conjunction of soul and body could experience suffering. The theory that the affection of the body modifies it so as to produce a sensation which itself would end in the soul, leaves unexplained the origin of sensation. To the theory that suffering has its principle in this opinion or judgment, that a misfortune is happening to ourselves or some one related to us, whence results disagreeable emotion first in the body, and then in the whole living organism, there is this objection, that it is yet uncertain to which opinion belongs; to the soul, or to the conjunction of soul and body. Besides, the opinion of the presence of an evil does not always entail suffering; it is possible that, in spite of such an opinion, one feels no affliction; as, for instance, one may not become irritated at believing oneself scorned; or in experiencing no desire even in the expectation of some good.
