2. The great mark of a passion is its sensible working of itself out upon the body,—what Dr. Bain calls "the diffusive wave of emotion." Without this mark there is no passion, but with it are other mental states besides passions, as we define them. All strong emotion affects the body sensibly, but not all emotions are passions. There are emotions that arise from and appertain to the rational portion of the soul. Such are Surprise, Laughter, Shame.
There is no sense of humour in any but rational beings; and though dogs look ashamed and horses betray curiosity, that is only inasmuch as in these higher animals there is something analogous to what is reason in man. Moreover passions are conversant with good and evil affecting sense, but the objects of such emotions as those just mentioned are not good and evil as such, common parlance notwithstanding, whereby we are said to laugh at a bon mot, or "a good thing."
3. Love is a generic passion, having for its species desire and delight, the contraries of which are abhorrence and pain. Desire is of absent good; abhorrence is of absent evil; delight is in present good; pain is at present evil. The good and the evil which is the object of any passion must be apprehended by sense, or by imagination in a sensible way, whether itself be a thing of sense or not.
4. Desire and abhorrence, delight and pain, are conversant with good and evil simply. But good is often attainable only by an effort, and evil avoidable by an effort. The effort that good costs to attain casts a shade of evil or undesirableness over it: we may shrink from the effort while coveting the good. Again, the fact of evil being at all avoidable is a good thing about such evil. If we call evil black, and good white, avoidable evil will be black just silvering into grey: and arduous good will be white with a cloud on it. And if the white attracts, and the black repels the appetite, it appears that arduous good is somewhat distasteful, to wit, to the faint-hearted; and avoidable, or vincible, evil has its attraction for the man of spirit. About these two objects, good hard of getting and evil hard of avoidance, arise four other passions, hope and despair about the former, fear and daring about the latter. Hope goes out towards a difficult good: despair flies from it, the difficulty here being more repellent than the good is attractive. Fear flies from a threatening evil: while daring goes up to the same, drawn by the likelihood of vanquishing it. Desire and abhorrence, delight and pain, hope and despair, fear and daring, with anger and hatred (of which presently), complete our list of passions.
5. Aristotle and his school of old, called Peripatetics, recommended the moderation of the passions, not their extirpation. The Stoics on the other hand contended that the model man, the sage, should be totally devoid of passions. This celebrated dispute turned largely on the two schools not understanding the same thing by the word passion. Yet not entirely so. There was a residue of real difference, and it came to this. If the sensitive appetite stirs at all, it must stir in one or other of nine ways corresponding to the nine passions which we have enumerated. Such an emotion as Laughter affects the imagination and the sensitive part of man, and of course the body visibly, but it does not stir the sensitive appetite, since it does not prompt to action. To say then that a man has no passions, means that the sensitive appetite never stirs within him, but is wholly dead. But this is impossible, as the Stoic philosopher was fain to confess when he got frightened in a storm at sea. Having no passions cannot in any practical sense mean having no movements of the sensitive appetite, for that will be afoot of its own proper motion independent of reason: but it may mean cherishing no passions, allowing none to arise unresisted, but suppressing their every movement to the utmost that the will can. In that sense it is a very intelligible and practical piece of advice, that the wise man should labour to have no passions. It is the advice embodied in Horace's Nil admirari, Talleyrand's "No zeal," Beaconsfield's "Beware of enthusiasm." It would have man to work like a scientific instrument, calm as a chronometer, regulated by reason alone. This was the Stoic teaching, this the perfection that they inculcated, quite a possible goal to make for, if not to attain. And it is worth a wise man's while to consider, whether he should bend his efforts in this direction or not. The determination here taken and acted upon will elaborate quite a different character of man one way or the other. The effort made as the Stoics direct, would mean no yielding to excitement, no poetry, no high-strung devotion, no rapture, no ecstasy, no ardour of love, no earnest rhetoric spoken or listened to, no mourning, no rejoicing other than the most conventional, to the persistent smothering of whatever is natural and really felt, no tear of pity freely let flow, no touch of noble anger responded to, no scudding before the breeze of indignation,—all this, that reason may keep on the even tenour of her way undisturbed.
6. The fault in this picture is that it is not the picture of a man, but of a spirit. He who being man should try to realize it in himself, would fall short of human perfection. For though the sensitive appetite is distinguished from the will, and the two may clash and come in conflict, yet they are not two wholly independent powers, but the one man is both will and sensitive appetite, and he rarely operates according to one power without the other being brought into corresponding play. There is a similar concomitance of the operations of intellect and imagination. What attracts the sensitive appetite, commonly allures also the affective will, though on advertence the elective will may reject it. On the other hand, a strong affection and election of the will cannot be without the sensitive appetite being stirred, and that so strongly that the motion is notable in the body,—in other words, is a passion. Passion is the natural and in a certain degree the inseparable adjunct of strong volition. To check one is to check the other. Not only is the passion repressed by repressing the volition, but the repression of the passion is also the repression of the volition. A man then who did his best to repress all movements of passion indiscriminately, would lay fetters on his will, lamentable and cruel and impolitic fetters, where his will was bent on any object good and honourable and well-judged.
7. Again, man's will is reached by two channels, from above downwards and from below upwards: it is reached through the reason and through the imagination and senses. By the latter channel it often receives evil impressions, undoubtedly, but not unfrequently by the former also. Reason may be inconsiderate, vain, haughty, mutinous, unduly sceptical. The abuse is no justification for closing either channel. Now the channel of the senses and of the imagination is the wider, and in many cases affords the better passage of the two. The will that is hardly reached by reason, is approached and won by a pathetic sight, a cry of enthusiasm, a threat that sends a tremor through the limbs. Rather I should say the affective will is approached in this way: for it remains with the elective will, on advertence and consultation with reason, to decide whether or not it shall be won to consent. But were it not for the channel of passion, this will could never have been approached at all even by reasons the most cogent. Rhetoric often succeeds, where mere dry logic would have been thrown away. God help vast numbers of the human race, if their wills were approachable only through their reasons! They would indeed be fixtures.
8. Another fact to notice is the liability of reason's gaze to become morbid and as it were inflamed by unremitting exercise. I do not here allude to hard study, but to overcurious scanning of the realities of this life, and the still greater realities and more momentous possibilities of the world to come. There is a sense of the surroundings being too much for us, an alarm and a giddiness, that comes of sober matter-of-fact thought over-much prolonged. Then it happens that one or more undeniable truths are laid hold of, and considered in strong relief and in isolation from the rest: the result is a distorted and partial view of truth as a whole, and therewith the mind is troubled. Here the kindlier passions, judiciously allowed to play, come in to soothe the wound and soreness of pure intellect, too keen in its workings for one who is not yet a pure spirit.
9. Moral good and evil are predicable only of human acts, in the technical sense of the term. (c. i., nn. 2—4, p. 41.) As the passions by definition (c. iv., s. i., n. 1, p. 41) are not human acts, they can never be morally evil of themselves. But they are an occasion of moral evil in this way. They often serve to wake up the slumbering Reason. To that end it is necessary that they should start up of themselves without the call of Reason. This would be no inconvenience, if the instant Reason awoke, and adverted to the tumult and stir of Passion, she could take command of it, and where she saw fit, quell it. But Reason has no such command, except in cases where she has acquired it by years of hard fighting. Passion once afoot holds on her course against the dictate of Reason. True, so long as it remains mere Passion, and Reason is not dragged away by it, no consent of the will given, no voluntary act elicited, still less carried into outward effect,—so long as things remain thus, however Passion may rage, there is no moral evil done. But there is a great temptation, and in great temptation many men fall. The evil is the act of free will, but the pressure on the will is the pressure of Passion. But Passion happily is a young colt amenable to discipline. Where the assaults of Passion are resolutely and piously withstood, and the incentives thereto avoided—unnatural and unnecessary incentives I mean—Passion itself acquires a certain habit of obedience to Reason, which habit is moral virtue. Of that presently.
10. In a man of confirmed habits of moral virtue, Passion starts up indeed independently of Reason, but then Reason ordinarily finds little difficulty in regulating the Passion so aroused. In a certain high and extraordinary condition of human nature, not only has Reason entire mastery over Passion wherever she finds it astir, but Passion cannot stir in the first instance, without Reason calling upon it to do so. In this case the torpor of the will deprecated above (n. 7) is not to be feared, because Reason is so vigorous and so masterful as to be adequate to range everywhere and meet all emergencies without the goad of Passion. This state is called by divines the state of integrity. In it Adam was before he sinned. It was lost at the Fall, and has not been restored by the Redemption. It is not a thing in any way due to human nature: nothing truly natural to man was forfeited by Adam's sin. It is no point of holiness, no guerdon of victory, this state of integrity, but rather a being borne on angel's wings above the battle. But one who has no battle in his own breast against Passion, may yet suffer and bleed and die under exterior persecution: nay, he may, if he wills, let in Passion upon himself, to fear and grieve, when he need not. So did the Second Adam in the Garden of Gethsemane.
