[8] It has also been reckoned as a want of "method" in this work that I have often made use of a cautious and restrained mode of expression, that I have spoken of mere "suppositions" and employed locutions such as "it appears," &c., when it has been for the time being impossible for science or myself to give complete certainty to an assertion. This reproach sounds strange in the mouths of such as plume themselves upon "scientific method." For I should think that it was indeed more scientific in the given cases to express oneself in the manner chosen by me, than by an unmeasured certainty in assertions to puff out pure suppositions into undoubted facts. I must leave such a mode of proceeding to the historical theologians. They work purely with hypotheses. All their endeavours to obtain an historical kernel from the Gospels rest upon conjectures simply. Above everything, their explanation of the origin of Christianity simply from an historical Jesus is, in spite of the certainty and self-confidence with which it comes out, a pure hypothesis, and that of very doubtful value. For that in reality the new religion should have been called into life by the "all-subduing influence of the personality of Jesus" and its accompaniments, the visions and hallucinations of the disciples worked up into ecstasies, is so improbable, and the whole view is psychologically so assailable, and, moreover, so futile, that even a liberal theologian like Gunkel declares it entirely insufficient ("Zum religionsgesichtl. Verständnis d. N.T.," 89 sq.). With this explanation, however, stands or falls the whole modern Jesus-religion. For if they cannot show how the Pauline and Johannine Christology could develop from the mere existence of an historical Jesus, if this now forms "the problem of problems of New Testament research" (Gunkel, op. cit.), then their whole conception of the rise of Christianity disappears into air, and they have no right to hold up against others who seek a better explanation the partially hypothetical character of the views advanced by them.
