222. What is known, in a given case, is what is sure, certain, settled, disposed of; that which we think with rather than that which we think about. In its honorable sense, knowledge is distinguished from opinion, guesswork, speculation, and mere tradition. In knowledge, things are ascertained; they are so and not dubiously otherwise. But experience makes us aware that there is difference between intellectual certainty of subject matter and our certainty. We are made, so to speak, for belief; credulity is natural. The undisciplined mind is averse to suspense and intellectual hesitation; it is prone to assertion. It likes things undisturbed, settled, and treats them as such without due warrant. Familiarity, common repute, and congeniality to desire are readily made measuring rods of truth. Ignorance gives way to opinionated and current error,—a greater foe to learning than ignorance itself. A Socrates is thus led to declare that consciousness of ignorance is the beginning of effective love of wisdom, and a Descartes to say that science is born of doubting.

We have already dwelt upon the fact that subject matter, or data, and ideas have to have their worth tested experimentally: that in themselves they are tentative and provisional. Our predilection for premature acceptance and assertion, our aversion to suspended judgment, are signs that we tend naturally to cut short the process of testing. We are satisfied with superficial and immediate short-visioned applications. If these work out with moderate satisfactoriness, we are content to suppose that our assumptions have been confirmed. Even in the case of failure, we are inclined to put the blame not on the inadequacy and incorrectness of our data and thoughts, but upon our hard luck and the hostility of circumstance. We charge the evil consequence not to the error of our schemes and our incomplete inquiry into conditions (thereby getting material for revising the former and stimulus for extending the latter) but to untoward fate. We even plume ourselves upon our firmness in
