I have remarked, in a former paper, that credulity is the common failing of unexperienced virtue; and that he who is spontaneously suspicious, may be justly charged with radical corruption; for, if he has not known the prevalence of dishonesty by information, nor had time to observe it with his own eyes, whence can he take his measures of judgment but from himself? They who best deserve to escape the snares of artifice, are most likely to be entangled. He that endeavours to live for the good of others, must always be exposed to the arts of them who live only for themselves, unless he is taught by timely precepts the caution required in common transactions, and shewn at a distance the pitfalls of treachery. To youth, therefore, it should be carefully inculcated, that, to enter the road of life without caution or reserve, in expectation of general fidelity and justice, is to launch on the wide ocean without the instruments of steerage, and to hope that every wind will be prosperous, and that every coast will afford a harbour. To enumerate the various motives to deceit and injury, would be to count all the desires that prevail among the sons of men; since there is no ambition however petty, no wish however absurd, that by indulgence will not be enabled to overpower the influence of virtue. Many there are, who openly and almost professedly regulate all their conduct by their love of money; who have no other reason for action or forbearance, for compliance or refusal, than that they hope to gain more by one than by the other. These are indeed the meanest and cruellest of human beings, a race with whom, as with some pestiferous animals, the whole creation seems to be at war; but who, however detested or scorned, long continue to add heap to heap, and when they have reduced one to beggary, are still permitted to fasten on another. Others, yet less rationally wicked, pass their lives in mischief, because they cannot bear the sight of success, and mark out every man for hatred, whose fame or fortune they believe increasing. Many who have not advanced to these degrees of guilt are yet wholly unqualified for friendship, and unable to maintain any constant or regular course of kindness. Happiness may be destroyed not only by union with the man who is apparently the slave of interest, but with whom a wild opinion of the dignity of perseverance, in whatever cause, disposes to pursue every injury with unwearied and perpetual resentment; with him whose vanity inclines him to consider every man as a rival in every pretension; with him whose airy negligence puts his friend's affairs or secrets in continual hazard, and who thinks his forgetfulness of others excused by his inattention to himself; and with him whose inconstancy ranges without any settled rule of choice through varieties of friendship, and who adopts and dismisses favourites by the sudden impulse of caprice.
