The benevolent system, on the other hand, while it fosters and encourages all those milder virtues in the highest degree, seems entirely to neglect the more awful and respectable qualities of the mind. It even denies them the appellation of virtues. It calls them moral abilities, and treats them as qualities which do not deserve the same sort of esteem and approbation, that is due to what is properly denominated virtue. All those principles of action which aim only at our own interest, it treats, if that be possible, still worse. So far from having any merit of their own, they diminish, it pretends, the merit of benevolence, when they co-operate with it: and prudence, it is asserted, when employed only in promoting private interest, can never even be imagined a virtue. That system, again, which makes virtue consist in prudence only, while it gives the highest encouragement to the habits of caution, vigilance, sobriety, and judicious moderation, seems to degrade equally both the amiable and respectable virtues, and to strip the former of all their beauty, and the latter of all their grandeur. But notwithstanding these defects, the general tendency of each of those three systems is to encourage the best and most laudable habits of the human mind: and it were well for society, if, either mankind in general, or even those few who pretend to live according to any philosophical rule, were to regulate their conduct by the precepts of any one of them. We may learn from each of them something that is both valuable and peculiar. If it was possible, by precept and exhortation, to inspire the mind with fortitude and magnanimity, the ancient systems of propriety would seem sufficient to do this. Or if it was possible, by the same means, to soften it into humanity, and to awaken the affections of kindness and general love towards those we live with, some of the pictures with which the benevolent system presents us, might seem capable of producing this effect. We may learn from the system of Epicurus, though undoubtedly the worst of all the three, how much the practice of both the amiable and respectable virtues is conducive to our own interest, to our own ease and safety and quiet even in this life. As Epicurus placed happiness in the attainment of ease and security, he exerted himself in a particular manner to show that virtue was, not merely the best and the surest, but the only means of acquiring those invaluable possessions. The good effects of virtue, upon our inward tranquility and peace of mind, are what other philosophers have chiefly celebrated. Epicurus, without neglecting this topic, has chiefly insisted upon the influence of that amiable quality on our outward prosperity and safety. It was upon this account that his writings were so much studied in the ancient world by men of all different philosophical parties. It is from him that Cicero, the great enemy of the Epicurean system, borrows his most agreeable proofs that virtue
