THE SOUL FEELS THE PASSIONS WITHOUT EXPERIENCING THEM.
19. That is why there is pleasure and pain. That is why grief is said to be a perception of dissolution, when the body is threatened with the loss of the image of the soul (of being disorganized by losing the irrational soul). That is why it is said that pleasure is a perception produced in the animal when the image of the soul reassumes its sway over the body. It is the body which undergoes passion; but it is the sense-potentiality of the soul which perceives the passion by its relation with the organs; it is she to which all the sensations ultimately report themselves. The body alone is injured and suffers; for example, when one member is cut, it is the mass of the body which is cut; the soul feels pain not merely as a mass, but as a living mass. It is likewise with a burn: the soul feels it, because the sense-potentiality as it were receives its reaction by its relations with the organs. The soul entire feels the passion produced in the body without however herself experiencing it.
UNLESS THE SOUL WERE IMPASSIBLE SHE COULD NOT LOCALIZE AND MANAGE PAIN.
Indeed, as the whole soul feels, she localizes the passion in the organ which has received the blow, and which suffers. If she herself experienced the suffering, as the whole of her is present in the whole body, she could not localize the suffering in one organ; the whole of her would feel the suffering; she would not relate it to any one part of the body, but to all in general: for she is present everywhere in the body. The finger suffers, and the man feels this suffering, because it is his finger. It is generally said that the man suffers in his finger, just as it is said that he is blond, because his eyes are blue. It is therefore the same entity that undergoes passion and suffering, unless the word “suffering” should not here designate both the passion, and the sensation which follows it; in this case no more is meant than that the state of suffering is accompanied by sensation. The sensation itself is not the suffering, but the knowledge of the suffering. The potentiality which knows must be impassible to know well, and well to indicate what is perceived. For if the faculty which is to indicate the passions itself suffer, it will either not indicate them, or it will indicate them badly.
