The sentiment or affection of the heart from which any action proceeds, and upon which its whole virtue or vice must ultimately depend, may be considered under two different aspects, or in two different relations; first, in relation to the cause which excites it, or the motive which gives occasion to it; and secondly, in relation to the end which it proposes, or the effect which it tends to produce.

In the suitableness or unsuitableness, in the proportion or disproportion which the affection seems to bear to the cause or object which excites it, consists the propriety or impropriety, the decency or ungracefulness of the consequent action.

In the beneficial or hurtful nature of the effects which the affection aims at, or tends to produce, consists the merit or demerit of the action, the qualities by which it is entitled to reward, or is deserving of punishment.

Philosophers have, of late years, considered chiefly the tendency of affections, and have given little attention to the relation which they stand in to the cause which excites them. In common life, however, when we judge of any person’s conduct, and of the sentiments which directed it, we constantly consider them under both these aspects. When we blame in another man the excesses of love, of grief, of resentment, we not only consider the ruinous effects which they tend to produce, but the little occasion which was given for them. The merit of his favourite, we say, is not so great, his misfortune is not so dreadful, his provocation is not so extraordinary, as to justify so violent a passion. We should have indulged, we say; perhaps, have approved of the violence of his emotion, had the cause been in any respect proportioned to it.

When we judge in this manner of any affection, as proportioned or disproportioned to the cause which excites it, it is scarce possible that we should make use of any other rule or canon but the correspondent affection in ourselves. If, upon bringing the case home to our own breast, we find that the sentiments which it gives occasion to, coincide and tally with our own, we necessarily approve of them as proportioned and suitable to their objects; if otherwise, we necessarily disapprove of them, as extravagant and out of proportion.

Every faculty in one man is the measure by which he judges of the like faculty in another. I judge of your sight by my sight, of your ear by my ear, of your reason by my reason, of your resentment by my resentment, of your love by my love. I neither have nor can have any other way of judging about them.

CHAP. IV.
The same subject continued.

We may judge of the propriety or impropriety of the sentiments of another person by their correspondence or disagreement with our own, upon two different occasions; either, first, when the objects which excite them are considered without any peculiar relation, either to themselves or to the person whose sentiments we judge of; or, secondly, when they are considered as peculiarly affecting one or other of us.

1. With regard to those objects which are considered without any peculiar relation either to ourselves or to the person whose sentiments we judge of; wherever his sentiments intirely correspond with our own, we ascribe to him the qualities of taste and good judgment. The beauty of a plain, the greatness of a mountain, the ornaments of a building, the expression of a picture, the composition of a discourse, the conduct of a third person, the proportions of different quantities and numbers, the various appearances which the great machine of the universe is perpetually exhibiting, with the secret wheels and springs which produce them; all the general subjects of science and taste, are what we and our companions regard, as having no peculiar relation to either of us. We both look at them from the same point of view, and we have no occasion for sympathy, or for that imaginary change of situations from which it arises, in order to produce, with regard to these, the most perfect harmony of sentiments and affections. If, notwithstanding, we are often differently affected, it arises either from the different degrees of attention, which our different habits of life allow us to give easily to the several parts of those complex objects, or from the different degrees of natural acuteness in the faculty of the mind to which they are addressed.

When the sentiments of our companion coincide with our own in things of this kind, which are obvious and easy, and in which, perhaps, we never found a single person who differed from us, though we, no doubt, must approve of them, yet he seems to deserve no praise or admiration on account of them. But when they not only coincide with our own, but lead and direct our own; when in forming them he appears to have attended to many things which we had overlooked, and to have adjusted them to all the various circumstances of their objects; we not only approve of them, but wonder and are surprised at their uncommon and unexpected acuteness and comprehensiveness, and he appears to deserve a very high degree of admiration and applause. For approbation heightened by wonder and surprise, constitutes the sentiment which is properly palled admiration, and of which applause is the natural expression. The decision of the man who judges that exquisite beauty is preferable to the grossest deformity, or that twice two are equal to four, must certainly be approved of by all the world, but will not, surely, be much admired. It is the acute and delicate discernment of the man of taste, who distinguishes the minute, and scarce perceptible, differences of beauty and deformity; it is the comprehensive accuracy of the experienced mathematician, who unravels, with ease, the most intricate and perplexed proportions; it is the great leader in science and taste, the man who directs and conducts our own sentiments, the extent and superior justness of whole talents astonish us with wonder and surprise, who excites our admiration and seems to deserve our applause: and upon this foundation is grounded the greater part of the praise which is bestowed upon what are called the intellectual virtues.
