own case, is capable only of destruction, not of construction; of discovering error, not of finding truth; of finding reasons and counter-reasons, of exciting doubt and controversy, not of vouchsafing certitude. So long as it contents itself with controverting that which is false, it is potent and salutary; but when, despising divine assistance, it advances beyond this, it becomes dangerous, like a caustic drug which attacks the healthy flesh after it has consumed that which was diseased. [Footnote 1: Cf. on Bayle, L. Feuerbach. 1838, 2d ed., 1844; Eucken in the _Allgemeine Zeitung_, supplement to Nos. 251, 252, October 27, 28, 1891.] [Footnote 2: Thus, in regard to the problem of freedom, he finds it hard to comprehend how the creatures, who are not the authors of their own existence, can be the authors of their own actions, but, at the same time, inadmissible to think of God as the cause of evil. He seeks only to show the indemonstrability and incomprehensibility of freedom, not to reject it. For he sees in it the condition of morality, and calls attention to the fact that the difficulties in which those who deny freedom involve themselves are far greater than those of their opponents. He shows himself entirely averse to the determinism and pantheism of Spinoza.] He who seeks to refute skepticism must produce a criterion of truth. If such exists, it is certainly that advanced by Descartes, the evidence, the evident clearness of a principle. Well, then, the following principles pass for evident: That one, who does not exist, can have no responsibility for an evil action; that two things, which are identical with the same thing, are identical with each other; that I am the same man to-day that I was yesterday. Now, the revealed doctrines of original sin and of the Trinity show that the first and second of these axioms are false, and the Church doctrine of the preservation of the world as a continuous creation, that the last principle is uncertain. Thus if not even self-evidence furnishes us a criterion of truth, we must conclude that none whatever exists. Further, in regard to the origin of the world from a single principle, its creation by God, we find this supported, no doubt, both by the conclusions of the pure reason and by the consideration of nature, but controvened by the fact of evil, by the misery and wickedness of man. Is it conceivable that a holy and benevolent God has created so unhappy and wicked a being?
