Error, sed variis illudit partibus.
Hor. Lib. ii. Sat iii. 48.
While mazy error draws mankind astray
From truth's sure path, each takes his devious way;
One to the right, one to the left recedes,
Alike deluded, as each fancy leads.
Elphinston.
It is easy for every man, whatever be his character with others, to find reasons for esteeming himself, and therefore censure, contempt, or conviction of crimes, seldom deprive him of his own favour. Those, indeed, who can see only external facts, may look upon him with abhorrence? but when he calls himself to his own tribunal, he finds every fault, if not absolutely effaced, yet so much palliated by the goodness of his intention, and the cogency of the motive, that very little guilt or turpitude remains; and when he takes a survey of the whole complication of his character, he discovers so many latent excellencies, so many virtues that want but an opportunity to exert themselves in act, and so many kind wishes for universal happiness, that he looks on himself as suffering unjustly under the infamy of single failings, while the general temper of his mind is unknown or unregarded.
It is natural to mean well, when only abstracted ideas of virtue are proposed to the mind, and no particular passion turns us aside from rectitude; and so willing is every man to flatter himself, that the difference between approving laws, and obeying them, is frequently forgotten; he that acknowledges the obligations of morality, and pleases his vanity with enforcing them to others, concludes himself zealous in the cause of virtue, though he has no longer any regard to her precepts, than they conform to his own desires; and counts himself among her warmest lovers, because he praises her beauty, though every rival steals away his heart.
There are, however, great numbers who have little recourse to the refinements of speculation, but who yet live at peace with themselves, by means which require less understanding, or less attention. When their hearts are burthened with the consciousness of a crime, instead of seeking for some remedy within themselves, they look round upon the rest of mankind, to find others tainted with the same guilt: they please themselves with observing, that they have numbers on their side; and that, though they are hunted out from the society of good men, they are not likely to be condemned to solitude.
