In the next place, when a passion hath for its foundation an original propensity peculiar to some men, it generally comes soon to maturity: the propensity, upon presenting a proper object, is immediately enlivened into a passion; which is the case of pride, of envy, and of malice.
In the third place, the growth of love and of hatred is slow or quick according to circumstances: the good qualities of a person raise in me a pleasant emotion; which, by reiterated views, is swelled into a passion involving desire of that person’s happiness: this desire, being freely indulged, works gradually a change internally, and at last produceth in me a settled habit of affection for that person, now my friend. Affection thus produced operates precisely like an original propensity; for to enliven it into a passion, no more is required but the real or ideal presence of the object. The habit of aversion or of hatred is brought on in the same manner. And here I must observe by the way, that love and hatred signify commonly<120> affection and aversion, not passion. The bulk of our passions are indeed affection or aversion inflamed into a passion by different circumstances: the affection I bear to my son, is inflamed into the passion of fear when he is in danger; becomes hope when he hath a prospect of good fortune; becomes admiration when he performs a laudable action; and shame when he commits any wrong: aversion becomes fear when there is a prospect of good fortune to my enemy; becomes hope when he is in danger; becomes joy when he is in distress; and sorrow when a laudable action is performed by him.
Fourthly,34 passions generally have a tendency to excess, occasioned by the following means. The mind affected by any passion, is not in a proper state for distinct perception, nor for cool reflection: it hath always a strong bias to the object of an agreeable passion, and a bias no less strong against the object of a disagreeable passion. The object of love, for example, however indifferent to others, is to the lover’s conviction a paragon; and of hatred, is vice itself without alloy. What less can such delusion operate, than to swell the passion beyond what it was at first? for if the seeing or conversing with a fine woman, have had the effect to carry me from indifference to love; how much stronger must her influence be, when now to my conviction she is an angel? and hatred as well as other passions must run the same course.<121> Thus between a passion and its object there is a natural operation, resembling action and reaction in physics: a passion acting upon its object, magnifies it greatly in appearance; and this magnified object reacting upon the passion, swells and inflames it mightily.
Fifthly, the growth of some passions depends often on occasional circumstances: obstacles to gratification, for example, never fail to augment and inflame a passion; because a constant endeavour to remove an obstacle, preserves the object of the passion ever in view, which swells the passion by impressions frequently reiterated: thus the restraint of conscience, when an obstacle to love, agitates the mind and inflames the passion:
Quod licet, ingratum est: quod non licet, acrius urit.
Si nunquam Danaën habuisset ahenea turris,
Non esset Danaë de Jove facta parens.
Ovid, Amor. l. 2.35
At the same time, the mind, distressed with the obstacle, becomes impatient for gratification, and consequently more desirous of it. Shakespear expresses this observation finely:
All impediments in fancy’s course,
Are motives of more fancy.36
We need no better example than a lover who hath many rivals. Even the caprices of a mistress have<122> the effect to inflame love; these occasioning uncertainty of success, tend naturally to make the anxious lover over-value the happiness of fruition.
So much upon the growth of passions: their continuance and decay come next under consideration. And, first, it is a general law of nature, That things sudden in their growth are equally sudden in their decay. This is commonly the case of anger. And with respect to wonder and surprise, which also suddenly decay, another reason concurs, that their causes are of short duration: novelty soon degenerates into familiarity; and the unexpectedness of an object, is soon sunk in the pleasure that the object affords. Fear, which is a passion of greater importance as tending to self-preservation, is often instantaneous; and yet is of equal duration with its cause: nay, it frequently subsists after the cause is removed.
In the next place, a passion founded on a peculiar propensity, subsists generally for ever; which is the case of pride, envy, and malice: objects are never wanting to inflame the propensity into a passion.
Thirdly, it may be laid down as a general law of nature, That every passion ceases upon attaining its ultimate end. To explain that law, we must distinguish between a particular and a general end. I call a particular end what may be accomplished by a single act: a general end, on the contrary, admits acts without number; because it<123> cannot be said, that a general end is ever fully accomplished, while the object of the passion subsists. Gratitude and revenge are examples of the first kind: the ends they aim at may be accomplished by a single act; and when that act is performed, the passions are necessarily at an end. Love and hatred are examples of the other kind; desire of doing good or of doing mischief to an individual, is a general end, which admits acts without number, and which seldom is fully accomplished: therefore these passions have frequently the same duration with their objects.
Lastly, it will afford us another general view, to consider the difference between an original propensity, and affection or aversion produced by custom. The former adheres too close to the constitution ever to be eradicated; and for that reason, the passions to which it gives birth, continue during life with no remarkable diminution. The latter, which owe their birth and increment to time, owe their decay to the same cause: affection and aversion decay gradually as they grow; and accordingly hatred as well as love are extinguished by long absence. Affection decays more gradually between persons who, living together, have daily occasion to testify mutually their good-will and kindness: and when affection is decay’d, habit supplies its place; for it makes these persons necessary to each other, by the pain of separa-<124>tion.* Affection to children hath a long endurance, longer perhaps than any other affection: its growth keeps pace with that of its objects: they display new beauties and qualifications daily, to feed and augment the affection. But whenever the affection becomes stationary, it must begin to decay; with a slow pace indeed, in proportion to its increment. In short, man with respect to this life is a temporary being: he grows, becomes stationary, decays; and so must all his powers and passions.
Coexistent Emotions and Passions.
For a thorough knowledge of the human passions and emotions, it is not sufficient that they be examined singly and separately: as a plurality of them are sometimes felt at the same instant, the manner of their coexistence, and the effects thereby produced, ought also to be examined. This subject is extensive, and it will be difficult to trace all the laws that govern its endless variety of cases: if such an undertaking can be brought to perfection, it must be by degrees. The following hints may suffice for a first attempt.<125>
We begin with emotions raised by different sounds, as the simplest case. Two sounds that mix, and, as it were, incorporate before they reach the ear, are said to be concordant. That each of the two sounds, even after their union, produceth an emotion of its own, must be admitted: but these emotions, like the sounds that produce them, mix so intimately, as to be rather one complex emotion than two emotions in conjunction. Two sounds that refuse incorporation or mixture, are said to be discordant: and when heard at the same instant, the emotions produced by them are unpleasant in conjunction, however pleasant separately.
Similar to the emotion raised by mixed sounds, is the emotion raised by an object of sight with its several qualities: a tree, for example, with its qualities of colour, figure, size,
