When rich food is brought down by ingredients of a plainer taste, the composition is susceptible of a specific habit. Thus the sweet taste of sugar, rendered less poignant in a mixture, may, in course of time, produce a specific habit for such mixture. As moderate pleasures, by becoming more intense, tend to generic habits; so intense pleasures, by becoming more moderate, tend to specific habits. The beauty of the human figure, by a special recommendation of nature, appears to us supreme, amid the great variety of beauteous forms bestowed upon animals. The various degrees in which individuals enjoy this property, render it an object sometimes of a moderate sometimes of an intense passion. The moderate passion, admitting frequent reiteration without diminution, and occupying the mind without exhausting it, becomes gradually stronger till it settle in a habit. So true this is, that instances are not wanting, of an ugly face, at first disagreeable, afterward rendered indifferent by familiarity, and at the longrun agreeable. On the other hand, consummate beauty, at the very first view, fills the mind so as to admit no increase. Enjoyment in this case lessens the pleasure[29]; and if often repeated, ends commonly in satiety and disgust. Constant experience shows, that the emotions created by great beauty become weaker by familiarity. The impressions made successively by such an object, strong at first and lessening by degrees, constitute a series opposite to that of the weak and increasing emotions, which grow into a specific habit. But the mind, when accustomed to beauty, contracts a relish for it in general, though often repelled from particular objects by the pain of satiety. Thus a generic habit is formed, of which inconstancy in love is the necessary consequence. For a generic habit, comprehending every beautiful object, is an invincible obstruction to a specific habit, which is confined to one.
