Since it is impossible to deny secular alterations in our sentiments and needs, it would be absurd to affirm that one’s own age of the world can be beyond correction by the next age. Skepticism cannot, therefore, be ruled out by any set of thinkers as a possibility against which their conclusions are secure; and no empiricist ought to claim exemption from this universal liability. But to admit one’s liability to correction is one thing, and to embark upon a sea of wanton doubt is another. Of willfully playing into the hands of skepticism we cannot be accused. He who acknowledges the imperfectness of his instrument, and makes allowance for it in discussing his observations, is in a much better position for gaining truth than if he claimed his instrument to be infallible. Or is dogmatic or scholastic theology less doubted in point of fact for claiming, as it does, to be in point of right undoubtable? And if not, what command over truth would this kind of theology really lose if, instead of absolute certainty, she only claimed reasonable probability for her conclusions? If _we_ claim only reasonable probability, it will be as much as men who love the truth can ever at any given moment hope to have within their grasp. Pretty surely it will be more than we could have had, if we were unconscious of our liability to err. Nevertheless, dogmatism will doubtless continue to condemn us for this confession. The mere outward form of inalterable certainty is so precious to some minds that to renounce it explicitly is for them out of the question. They will claim it even where the facts most patently pronounce its folly. But the safe thing is surely to recognize that all the insights of creatures of a day like ourselves must be provisional. The wisest of critics is an altering being, subject to the better insight of the morrow, and right at any moment, only “up to date” and “on the whole.” When larger ranges of truth open, it is surely best to be able to open ourselves to their reception, unfettered by our previous pretensions. “Heartily know, when half‐gods go, the gods arrive.”
