—Against this let us set the different manner in which we (—you observe that I am courteous enough to say “we”) conceive the problem of the error and deceptiveness of things. Formerly people regarded change and evolution in general as the proof of appearance, as a sign of the fact that something must be there that leads us astray. To-day, on the other hand, we realise that precisely as far as the rational bias forces us to postulate unity, identity, permanence, substance, cause, materiality and being, we are in a measure involved in error, driven necessarily to error; however certain we may feel, as the result of a strict examination of the matter, that the error lies here. It is just the same here as with the motion of the sun: In its case it was our eyes that were wrong; in the matter of the concepts above mentioned it is our language itself that pleads most constantly in their favour. In its origin language belongs to an age of the most rudimentary forms of psychology: if we try to conceive of the first conditions of the metaphysics of language, _i.e._ in plain English, of reason, we immediately find ourselves in the midst of a system of fetichism. For here, the doer and his deed are seen in all circumstances, will is believed in as a cause in general; the ego is taken for granted, the ego as Being, and as substance, and the faith in the ego as substance is projected into all things—in this way, alone, the concept “thing” is created. Being is thought into and insinuated into everything as cause; from the concept “ego,” alone, can the concept “Being” proceed. At the beginning stands the tremendously fatal error of supposing the will to be something that actuates,—a faculty. Now we know that it is only a word.[1] Very much later, in a world a thousand times more enlightened, the assurance, the subjective certitude, in the handling of the categories of reason came into the minds of philosophers as a surprise. They concluded that these categories could not be derived from experience,—on the contrary, the whole of experience rather contradicts them. _Whence do they come therefore?_ In India, as in Greece, the same mistake was made: “we must already once have lived in a higher world (—instead of in a much lower one, which would have been the truth!), we must have been divine, for we possess reason!” ... Nothing indeed has exercised a more simple power of persuasion hitherto than the error of Being, as it was formulated by the Eleatics for instance: in its favour are every word and every sentence that we utter!—Even the opponents of the Eleatics succumbed to the seductive powers of their concept of Being. Among others there was Democritus in his discovery of the atom. “Reason” in language!—oh what a deceptive old witch it has been! I fear we shall never be rid of God, so long as we still believe in grammar. 6
