paths, free to make things so by thinking them so, free to set method and learning and experience at naught. And surely it calls for braveness of no common order to resist the seductive appeals of eye and ear, to sail steadily on heedless of the calls of the sirens of rationality, convinced at the outset that things cannot be as they are, and refusing the nod of recognition to the plebeian idols of the ills of flesh. It is not necessary in this connection to recount the beliefs of this system; it is sufficient to point out that when thousands of intelligent persons give practical adherence to, and enroll themselves under the banner of, one who teaches that a bunion would be an adequate cause of insanity, if only we held the same belief about the bunion as we do about congestion of the brain; that smallpox is contagious by reason of the same agencies as make weeping or yawning contagious; that fear may be reflected in the body as fractured bones, just as shame is seen rising to the cheek; that anatomy and physiology and hygiene are the husbandmen of sickness and disease, while the reading of a text-book of Christian Science is equally effective in producing health; or that when a healthy horse takes cold without his blanket, it is on account of the poor creature’s knowledge of physiology—then such persons can hardly complain if they are cited as instances of modern credulity.

Such, then, is the background against which logical belief shines forth with contrasted splendor; such are, admittedly in their extreme form, the results of following after strange gods and deserting the narrow path of strenuous rationality, of critically trained judgment, of adherence to verifiable standards of belief. The tale needs no adornment, and the moral is sufficiently pointed to require no hard blows to drive it home. It will be profitable in continuation to survey, tho perforce briefly, the middle distance, the practical field of compromise and of the necessity for action, in which we must needs travel up hill and down dale and cannot take the level road which we wish were possible, in which we must risk error constantly if we would move at all.
