"Persuaded, then, that knowledge contained the key to virtue, it was to knowledge that I applied. The first grand lesson which it taught me was the solution of a phrase most hackneyed, least understood; namely, 'common-sense.' [Koinonoaemosunae, sensus communis.] It is in the Portico of the Greek sage that that phrase has received its legitimate explanation; it is there we are taught that 'common-sense' signifies 'the sense of the common interest.' Yes! it is the most beautiful truth in morals that we have no such thing as a distinct or divided interest from our race. In their welfare is ours; and, by choosing the broadest paths to effect their happiness, we choose the surest and the shortest to our own. As I read and pondered over these truths, I was sensible that a great change was working a fresh world out of the former materials of my mind. My passions, which before I had checked into uselessness, or exerted to destruction, now started forth in a nobler shape, and prepared for a new direction: instead of urging me to individual aggrandizement, they panted for universal good, and coveted the reward of Ambition only for the triumphs of Benevolence." "This is one stage of virtue; I cannot resist the belief that there is a higher: it is when we begin to love virtue, not for its objects, but itself. For there are in knowledge these two excellences: first, that it offers to every man, the most selfish and the most exalted, his peculiar inducement to good. It says to the former, 'Serve mankind, and you serve yourself;' to the latter, 'In choosing the best means to secure your own happiness, you will have the sublime inducement of promoting the happiness of mankind.'" "The second excellence of Knowledge is that even the selfish man, when he has once begun to love Virtue from little motives, loses the motives as he increases the love; and at last worships the deity, where before he only coveted the gold upon its altar." "And thus I learned to love Virtue solely for its own beauty. I said with one who, among much dross, has many particles of ore, 'If it be not estimable in itself, I can see nothing estimable in following it for the sake of a bargain.' [Lord Shaftesbury.] "I looked round the world, and saw often Virtue in rags and Vice in purple: the former conduces to happiness, it is true, but the happiness lies within and not in externals. I contemned the deceitful folly with which writers have termed it poetical justice to make the good ultimately prosperous in wealth, honour, fortunate love, or successful desires. Nothing false, even in poetry, can be just; and that pretended moral is, of all, the falsest. Virtue is not more exempt than Vice from the ills of fate, but it contains within itself always an energy to resist them, and sometimes an anodyne to soothe,-- to repay your quotation from Tibullus,-- 'Crura sonant ferro, sed canit inter opus!'" ["The chains clank on its limbs, but it sings amidst its tasks."]
