These researches, however, when they came to take place, confirmed those original anticipations of nature. Upon whatever we suppose that our moral faculties are founded, whether upon a certain modification of reason, upon an original instinct, called a moral sense, or upon some other principle of our nature, it cannot be doubted, that they were given us for the direction of our conduct in this life. They carry along with them the most evident badges of this authority, which denote that they were set up within us to be the supreme arbiters of all our actions, to superintend all our senses, passions, and appetites, and to judge how far each of them was either to be indulged or restrained. Our moral faculties are by no means, as some have pretended, upon a level in this respect with the other faculties and appetites of our nature, endowed with no more right to restrain these last, than these last are to restrain them. No other faculty or principle of action judges of any other. Love does not judge of resentment, nor resentment of love. Those two passions may be opposite to one another, but cannot, with any propriety, be said to approve or disapprove of one another. But it is the peculiar office of those faculties now under our consideration to judge, to bestow censure or applause upon all the other principles of our nature. They may be considered as a sort of senses of which those principles are the objects. Every sense is supreme over its own objects. There is no appeal from the eye with regard to the beauty of colours, nor from the ear with regard to the harmony of sounds, nor from the taste with regard to the agreeableness of flavours. Each of those senses judges in the last resort of its own objects. Whatever gratifies the taste is sweet, whatever pleases the eye is beautiful, whatever sooths the ear is harmonious. The very essence of each of those qualities consists in being fitted to please the sense to which it is addressed. It belongs to our moral faculties, in the same manner to determine when the ear ought to be soothed, when the eye ought to be indulged, when the taste ought to be gratified, when and how far every other principle of our nature ought to be indulged or restrained. What is agreeable to our moral faculties, is fit, and right, and proper to be done; the contrary wrong, unfit, and improper. The sentiments which they approve of, are graceful and unbecoming. The very words, right, wrong, fit, improper, graceful, unbecoming, mean only what pleases or displeases those faculties.
