Plutarch, An Recte Dictum Sit Latenter Esse Vivendum
Goodwin, Ed.

But besides, doth not the thing itself sound ill, to bid you keep all your lifetime out of the world's eye, as if you had rifled the sepulchres of the dead, or done such like detestable villany which you should hide for? What! is it grown a crime to live, unless you can keep all others from knowing you do so? For my part, I should pronounce that even an ill-liver ought not to withdraw himself from the converse of others. No; let him be known, let him be reclaimed, let him repent; so that, if you have any stock of virtue, let it not lie unemployed, or if you have been viciously bent, do not by flying the means continue unreclaimed and uncured. Point me out therefore and distinguish me the man to whom you adopt this admonition. If to one devoid of sense, goodness, or wit, it is like one that should caution a person under a fever or raving madness not to let it be known where he is, for fear the physicians should find him, but rather to skulk in some dark corner, where he and his diseases may escape discovery. So you who labor under that pernicious, that scarce curable disease, wickedness, are by parity of reason bid to conceal your vices, your envyings, your superstitions, like some disorderly or feverous pulse, for fear of falling into the hands of them who might prescribe well to you and set you to rights again. Whereas, alas! in the days of remote antiquity, men exhibited the sick to public view, when every charitable passenger who had labored himself under the like malady, or had experienced a remedy on them that did, communicated to the diseased all the receipts he knew; thus, say they, skill in physic was patched up by multiplied experiments, and grew to a mighty art. At the same rate ought all the infirmities of a dissolute life, all the irregular passions of the soul, to be laid open to the view of all, and undergo the touch of every skilful hand, [p. 5] that all who examine into the temper may be able to prescribe accordingly. For instance, doth anger transport you? The advice in that case is, Shun the occasions of it. Doth jealousy torment you? Take this or that course. Art thou love-sick? It hath been my own case and infirmity to be so too; but I saw the folly of it, I repented, I grew wiser. But for those that lie, denying, hiding, mincing, and palliating their vices, it makes them but take the deeper dye, it rivets their faults into them.
