“knowledge,” for something that is in the end solemnly christened “the Truth.” The fundamental belief of metaphysicians is THE BELIEF IN ANTITHESES OF VALUES.

It never occurred even to the wariest of them to doubt here on the very threshold (where doubt, however, was most necessary); though they had made a solemn vow, “DE OMNIBUS DUBITANDUM.” For it may be doubted, firstly, whether antitheses exist at all; and secondly, whether the popular valuations and antitheses of value upon which metaphysicians have set their seal, are not perhaps merely superficial estimates, merely provisional perspectives, besides being probably made from some corner, perhaps from below — ”frog perspectives,” as it were, to borrow an expression current among painters.
