These general features of the passions being stated, let us make a brief sketch of the principal passions.
It may be said that our passions pass through three distinct states; they are at first natural and unavoidable affections of the mind: inclinations, tendencies; they become next violent and unruly movements: these are the passions properly so-called; they become habits and embodied in the character, and take the name of qualities and defects, virtues and vices. But it is to be noted that whilst we can always distinguish these three states theoretically, language is, for the most part, inadequate to express them; for men have designated these moral states only according to the necessities of practice, and not according to the rules of theory.
The three states which we have just pointed out, can be very clearly distinguished in the first of the affections of human nature, namely, the instinct of self-preservation. This instinct is at first a natural, legitimate, necessary affection of the human heart; but by the force of circumstances, the influence of age, disease, temperament, it develops out of proportion into a state of passion, and becomes what we call fear; or else it turns into a habit and becomes the vice we call cowardice.
Physical self-preservation is inseparable from two appetites called hunger and thirst. These two appetites, too much indulged in, become passions, which themselves may become vices. But language fails here to express their various shades: there is only one word to express the passion or vice related to eating and drinking: it is on the one hand gluttony, and on the other drunkenness;[156] both these vices, and in general all undue surrender to sensual pleasures, is called intemperance.
The source of all our personal inclinations is the love for ourselves or self-love, a legitimate instinct when kept within bounds; but when carried to excess, when exclusive and predominant, it becomes the vice we call selfishness.
Self-esteem, developed into a passion, becomes, when it turns upon great things, false pride; when upon small, vanity.
The love of liberty degenerates into a spirit of revolt; the legitimate love of power, into ambition; the instinct of property becomes greed, cupidity, passion for gain, and tends to run into the passion for gambling or the desire to gain by means of chance. The desire for gain engenders the fear of loss, and this latter passion developing into a vice and mania, becomes avarice.
Human inclinations are divided into benevolent and malevolent inclinations. The first may develop into a passion, but not into a vice; the second alone become vices.
There is not a single benevolent inclination which, carried too far and beyond reason, may not become a more or less blameworthy passion. But, in the first place, we have no terms in our language to express the exaggerations of these kinds of passions,[157] and in the second, though they be exaggerations, we shall never call the tenderer affections of the human heart, however foolish they may be, vices, if they are sincere.
Yet, may some of these affections become vices when they unite with personal passion. For example, good nature or the desire to please may lead to obsequious servility, the desire to praise, to flattery, and esteem, to hypocrisy. But these vices partake more of the nature of self-love than of benevolent inclinations.
