XLV. This inattention, is without doubt what produces, and what keeps up in the world, men’s estimation for an infinite number of useless things, on which they bestow the noble epithet of remedies; and this false notion, has filled the medical books and the apothecaries shops, with an infinite deal of trash, the reading of which fatigues the memory; and the taking of which, ruins the health and constitution of the patient. You will find accumulated in them, a great number of remedies for slight diseases, which if left to nature, would cure themselves; and although all practitioners do not approve of the same remedy for the same disorder; does this prove, that the patient of each got better by taking this or that thing? I say does this prove it? for neither the imprudent sick person, nor those about him, hardly ever reflect, that there were many others besides him, who were affected with the same disorder, and who without taking any medicine at all, recovered as well, and as quickly as he did? XLVI. A benign or favourable sort of catarrh, as is very frequently the case, becomes epidemical in a city; for which, some call-in the doctor and take medicines, and others do not; and such is the blindness of those who have had advice as it is called, that they believe they owe the recovery of their health to the doctor, although they evidently see, that all those recovered as well as they, who had no advice, and who took no physic. XLVII. The delicate fine lady, who whenever she feels a slight pain in her head, sends for the doctor, is fully persuaded, although the pain continues for the space of twenty or thirty days, that the capital pills he prescribed for her, removed it; but it does not occur to the poor lady, that many of her friends and neighbours, who at times have the same sort of pains in their heads, and who take nothing for them, get well as soon, and frequently sooner, than she with the help of all her pills.
