19 This further point does not escape me, that the nature of all these objects of the watchfulness of the physician remains the same, and does not evolve out of itself any crafty opposition, or contrivance hostile to the appliances of his art, nay, it is rather the treatment which modifies its subject matter, except where some slight insubordination occurs on the part of the patient, which it is not difficult to prevent or restrain. But in our case, human prudence and selfishness, and the want of training and inclination to yield ready submission are a very great obstacle to advance in virtue, amounting almost to an armed resistance to those who are wishful to help us. And the very eagerness with which we should lay bare our sickness to our spiritual physicians, we employ in avoiding this treatment, and show our bravery by struggling against what is for our own interest, our skill in shunning what is for our health.
