natural sentiments of the bulk of mankind. It is to be observed, that so far as the sentiment of approbation arises from the perception of this beauty of utility, it has no reference of any kind to the sentiments of others. If it was possible, therefore, that a person should grow up to manhood without any communication with society, his own actions might, notwithstanding, be agreeable or disagreeable to him on account of their tendency to his happiness or disadvantage. He might perceive a beauty of this kind in prudence, temperance, and good conduct, and a deformity in the opposite behaviour: He might view his own temper and character with that sort of satisfaction with which we consider a well contrived machine, in the one case; or with that sort of distaste and dissatisfaction with which we regard a very awkward and clumsy contrivance, in the other. As these perceptions, however, are merely a matter of taste, and have all the feebleness and delicacy of that species of perceptions, upon the justness of which what is properly called taste is founded, they probably would not be much attended to by one in his solitary and miserable condition. Even though they should occur to him, they would by no means have the same effect upon him, antecedent to his connexion with society, which they would have in consequence of that connexion. He would not be cast down with inward shame at the thought of this deformity; nor would he be elevated with secret triumph of mind from the consciousness of the contrary beauty. He would not exult from the notion of deserving reward in the one case, nor tremble from the suspicion of meriting punishment in the other. All such sentiments suppose the idea of some other being, who is the natural judge of the person that feels them; and it is only by sympathy with the decisions of this arbiter of his conduct, that he can conceive, either the triumph of self-applause, or the shame of self-condemnation. PART V. Of the INFLUENCE of CUSTOM and FASHION upon the sentiments of moral approbation and disapprobation. CONSISTING OF ONE SECTION. CHAP. I. _Of the influence of custom and fashion upon our notions of beauty and deformity._ There are other principles besides those already enumerated, which have a considerable influence upon the moral sentiments of mankind, and are the chief causes of the many irregular and discordant opinions which prevail in different ages and nations concerning what is blameable or praise-worthy. These principles are custom and faction, principles which extend their dominion over our judgments concerning beauty of every kind.
