"To the ancients the world was a truth," says Feuerbach, but he forgets to make the important addition, "a truth whose untruth they tried to get back of, and at last really did." What is meant by those words of Feuerbach will be easily recognized if they are put alongside the Christian thesis of the "vanity and transitoriness of the world." For, as the Christian can never convince himself of the vanity of the divine word, but believes in its eternal and unshakeable truth, which, the more its depths are searched, must all the more brilliantly come to light and triumph, so the ancients on their side lived in the feeling that the world and mundane relations (_e. g_. the natural ties of blood) were the truth before which their powerless "I" must bow. The very thing on which the ancients set the highest value is spurned by Christians as the valueless, and what they recognized as truth these brand as idle lies; the high significance of the fatherland disappears, and the Christian must regard himself as "a stranger on earth";[8] the sanctity of funeral rites, from which sprang a work of art like the Antigone of Sophocles, is designated as a paltry thing ("Let the dead bury their dead"); the infrangible truth of family ties is represented as an untruth which one cannot promptly enough get clear of;[9] and so in everything. If we now see that to the two sides opposite things appear as truth, to one the natural, to the other the intellectual, to one earthly things and relations, to the other heavenly (the heavenly fatherland, "Jerusalem that is above," etc.), it still remains to be considered how the new time and that undeniable reversal could come out of antiquity. But the ancients themselves worked toward making their truth a lie. Let us plunge at once into the midst of the most brilliant years of the ancients, into the Periclean century. Then the Sophistic culture was spreading, and Greece made a pastime of what had hitherto been to her a monstrously serious matter. The fathers had been enslaved by the undisturbed power of existing things too long for the posterity not to have to learn by bitter experience to _feel themselves_. Therefore the Sophists, with courageous sauciness, pronounce the reassuring words, "Don't be bluffed!" and diffuse the rationalistic doctrine, "Use your understanding, your wit, your mind, against everything; it is by having a good and well-drilled understanding that one gets through the world best, provides for himself the best lot, the pleasantest _life_." Thus they recognize in _mind_ man's true weapon against the world. This is why they lay such stress on dialectic skill, command of language, the art of disputation, etc. They announce that mind is to be used against everything; but they are still far removed from the holiness of the Spirit, for to them it is a _means_, a weapon, as trickery and defiance serve children for the same purpose; their mind is the unbribable _understanding_.
