baron d' Paul Henri Thiry Holbach, Superstition in all ages
“ CLIV.—CHARLATANRY OF THE PRIESTS. What would we say of a crowd of quacks, who every day would exhibit in a public place, selling their remedies and recommending them as infallible, while we should find them afflicted with the same infirmities which they pretend to cure? Would we have much confidence in the recipes of these charlatans, who would bawl out: "Take our remedies, their effects are infallible—they cure everybody except us?" What would we think to see these same charlatans pass their lives in complaining that their remedies never produce any effect upon the patients who take them? ”
