DOES THE IRASCIBLE POWER ALSO ORIGINATE IN THE BODY?
28. Enough of this. Let us return to the question from which we digressed. We granted that the desires, pains and pleasures (considered not only as sentiments, but as passions), originate in the constitution of the organized and living body. Must the same origin be assigned to the irascible (power) ? Were this so, we would have several questions to ask: Does anger belong to the entire organism, or only to a particular organ, such as the heart when so disposed, or to the bile, as long as it is part of a living body? Is anger different from the principle which gives the body a trace of the soul, or is it an individual power, which depends on no other power, whether irascible or sensitive ?
THE LIVER IS THE SEAT OF THE SOUL’S FACULTY OF DESIRE.
The vegetative power present in the whole body communicates to every part thereof a trace of the soul. It is therefore to the entire body that we must refer suffering, pleasure, and the desire of food. Though nothing definite is ascertained about the seat of sexual desire, let us grant that their seat is in the organs destined to its satisfaction. Further, be it granted that the liver is the seat of the soul’s faculty of desire, because that organ is particularly the theatre of the activities of the vegetative power which impresses a trace of the soul on the body; and further, because it is from the liver that the action it exercises starts.
THE HEART IS THE SEAT OF ANGER.
As to anger, we shall have to examine its nature, what power of the soul it constitutes, whether it be anger that imparts to the heart a trace of its own power; if there exist another force capable of producing the movement revealed in the animal; and finally, if it be not a trace of anger, but anger itself which resides in the heart.
ANGER ORIGINATES IN THE VEGETATIVE AND GENERATIVE POWER, AS TRACE OF THE SOUL.
First, what is the nature of anger? We grow irritated at maltreatment of ourselves or of a person dear to us; in general, when we witness some outrage. Therefore anger implies a certain degree of sensation, or even intelligence, and we should have to suppose that anger originates in some principle other than the vegetative power. Certain bodily conditions, however, predispose us to anger; such as being of a fiery disposition, and being bilious; for people are far less disposed to anger if of a cold-blooded nature. Besides, animals grow irritated especially by the excitement of this particular part, and by threats of harm to their bodily condition. Consequently we would once more be led to refer anger to the condition of the body and to the principle which presides over the constitution of organism. Since men are more irritable when sick than when well, when they are hungry, more than when well satisfied, anger or its principle should evidently be referred to the organized and living body; evidently, attacks of anger are excited by the blood or the bile, which are living parts of the animal. As soon as the body suffers, the blood as well as the bile boils, and there arises a sensation which arouses the imagination; the latter then instructs the soul of the state of the organism, and disposes the soul to attack what causes this suffering. On the other hand, when the reasonable soul judges that we have been injured, she grows excited, even if there were no disposition to anger in the body. This affection seems therefore to have been given to us by nature to make us, according to the dictates of our reasons, repel and threatens us. (There are then two possible states of affairs) Either the irascible power first is moved in us without the aid of reason, and later communicates its disposition to reason by means of the imagination; or, reason first enters into action, and then reason communicates its impulse to that part of our being which is disposed to anger. In either case, anger arises in the vegetative and generative power, which, in organizing the body, has rendered it capable to seek out what is agreeable, and to avoid what is painful; diffusing the bitter bile through the organism, imparting to it a trace of the soul, thus communicating to it the faculty of growing irritated in the presence of harmful objects, and, after having been harmed, of harming other things, and to render them similar to itself. Anger is a trace of the soul, of the same nature as the soul’s faculty of desire, because those least seek objects agreeable to the body, and who even scorn the body, are least likely to abandon themselves to the blind transports of anger. Although plant-life possesses the vegetative power, it does not possess the faculty of anger because it has neither blood nor bile. These are the two things which, in the absence of sensation, leads one to boil with indignation. When however sensation joins these two elements, there arises an impulse to fight against the harmful object. If the irrational part of the soul were to be divided into the faculty of desire, and that of anger, and if the former were to be considered the vegetative power, and the other, on the contrary, as a trace of the vegetative power, residing in either the heart or blood, or in both; this division would not consist of opposed members, because the second would proceed from the first. But there is an alternative: both members of this division, the faculties of desire and anger, might be considered two powers derived from one and the same principle (the vegetative power). Indeed, when the appetites are divided, it is their nature, and not the being from which they depend, that is considered. This essence itself, however, is not the appetite, but completes it, harmonizing with it the actions proceeding from the appetite. It is also reasonable to assign the heart as seat of the trace of the soul which constitutes anger; for the heart is not the seat of the soul, but the source of the (arterially) circulating blood.
