It is to be remembered that a bodily infirmity is not the only thing to be corrected … the soul itself has received impressions that are incompatible with its reasoning powers. The subject, in all respects, requires great delicacy and address; and you must beware how you inveigh against the propensity; for the cravings of appetite for the poisonous draught are to the intemperate … as much as the inclinations of nature for a time, as a draught of cold water to a traveller panting with thirst in a desart (sic). Much vigilance will often be required in watching these cravings; for they are sometimes attended with modes of deceptions, and a degree of cunning, not to be equalled. ¹
