When I began to show that the dealers themselves in these intellectual wares were all the time charging one another of cheating, when I called to mind that in all times under the name of art and science much that was bad and harmful was offered to men, and that consequently in our time also the same danger was threatening, that this was no joke, that the poison for the soul was many times more dangerous than a poison for the body, and that therefore these spiritual products ought to be examined with the greatest attention when they are offered to us in the form of food, and everything counterfeit and deleterious ought to be rejected⁠—when I began to say this, no one, no one, not a single man in a single article or book made reply to these arguments, but from all the shops there was a chorus of cries against me as against the woman: “He is a fool! He wants to destroy art and science which we live by! Beware of him and do not heed him! Hear us, hear us! We have the very latest foreign wares!”
