None of those systems either give, or even pretend to give, any precise or distinct measure by which this fitness or propriety of affection can be ascertained or judged of. That precise and distinct measure can be found nowhere but in the sympathetic feelings of the impartial and well-informed spectator.
The description of virtue, besides, which is either given, or at least meant and intended to be given in each of those systems, for some of the modern authors are not very fortunate in their manner of expressing themselves, is no doubt quite just, so far as it goes. There is no virtue without propriety, and wherever there is propriety some degree of approbation is due. But still this description is imperfect. For though propriety is an essential ingredient in every virtuous action, it is not always the sole ingredient. Beneficent actions have in them another quality by which they appear not only to deserve approbation but recompense. None of those systems account either easily or sufficiently for that superior degree of esteem which seems due to such actions, or for that diversity of sentiment which they naturally excite. Neither is the description of vice more complete. For, in the same manner, though impropriety is a necessary ingredient in every vicious action, it is not always the sole ingredient; and there is often the highest degree of absurdity and impropriety in very harmless and insignificant actions. Deliberate actions, of a pernicious tendency to those we live with, have, besides their impropriety, a peculiar quality of their own by which they appear to deserve, not only disapprobation, but punishment; and to be the objects, not of dislike merely, but of resentment and revenge: and none of those systems easily and sufficiently account for that superior degree of detestation which we feel for such actions.

Of Those Systems Which Make Virtue Consist in Prudence
The most ancient of those systems which make virtue consist in prudence, and of which any considerable remains have come down to us, is that of Epicurus, who is said, however, to have borrowed all the leading principles of his philosophy from some of those who had gone before him, particularly from Aristippus; though it is very probable, notwithstanding this allegation of his enemies, that at least his manner of applying those principles was altogether his own.
According to Epicurus (Cicero De finibus, lib. I Diogenes Laert. 1. X) bodily pleasure and pain were the sole ultimate objects of natural desire and aversion. That they were always the natural objects of those passions, he thought required no proof. Pleasure might, indeed, appear sometimes to be avoided; not, however, because it was pleasure, but because, by the enjoyment of it, we should either forfeit some greater pleasure, or expose ourselves to some pain that was more to be avoided than this pleasure was to be desired. Pain, in the same manner, might appear sometimes to be eligible; not, however, because it was pain, but because by enduring it we might either avoid a still greater pain, or acquire some pleasure of much more importance. That bodily pain and pleasure, therefore, were always the natural objects of desire and aversion, was, he thought, abundantly evident. Nor was it less so, he imagined, that they were the sole ultimate objects of those passions. Whatever else was either desired or avoided, was so, according to him, upon account of its tendency to produce one or other of those sensations. The tendency to procure pleasure rendered power and riches desirable, as the contrary tendency to produce pain made poverty and insignificancy the objects of aversion. Honour and reputation were valued, because the esteem and love of those we live with were of the greatest consequence both to procure pleasure and to defend us from pain. Ignominy and bad fame, on the contrary, were to be avoided, because the hatred, contempt, and resentment of those we lived with, destroyed all security, and necessarily exposed us to the greatest bodily evils.
All the pleasures and pains of the mind were, according to Epicurus, ultimately derived from those of the body. The mind was happy when it thought of the past pleasures of the body, and hoped for others to come: and it was miserable when it thought of the pains which the body had formerly endured, and dreaded the same or greater thereafter.
But the pleasures and pains of the mind, though ultimately derived from those of the body, were vastly greater than their originals. The body felt only the sensation of the present instant, whereas the mind felt also the past and the future, the one by remembrance, the other by anticipation, and consequently both suffered and enjoyed much more. When we are under the greatest bodily pain, he observed, we shall always find, if we attend to it, that it is not the suffering of the present instant which chiefly torments us, but either the agonizing remembrance of the past, or the yet more horrible dread of the future. The pain of each instant, considered by itself, and cut off from all that goes before and all that comes after it, is a trifle, not worth the regarding. Yet this is all which the body can ever be said to suffer. In the same manner, when we enjoy the greatest pleasure, we shall always find that the bodily sensation, the sensation of the present instant, makes
