    As in another recent post I just came across this in Nietzsche's "Twilight of the Idols.' It strikes me on first reading as very persuasively consistent with Epicurus' defense of the senses and criticism of what we might call "otherworldliness." I'm posting it here for reference and future comment. Source link.


    "REASON" IN PHILOSOPHY

    1You ask me which of the philosophers' traits are really idiosyncrasies? For example, their lack of historical sense, their hatred of the very idea of becoming, their Egypticism. They think that they show their respect for a subject when they de-historicize it, sub specie aeternitas--when they turn it into a mummy. All that philosophers have handled for thousands of years have been concept-mummies; nothing real escaped their grasp alive. When these honorable idolators of concepts worship something, they kill it and stuff it; they threaten the life of everything they worship. Death, change, old age, as well as procreation and growth, are to their minds objections--even refutations. Whatever has being does not become; whatever becomes does not have being. Now they all believe, desperately even, in what has being. But since they never grasp it, they seek for reasons why it is kept from them. "There must be mere appearance, there must be some deception which prevents us from perceiving that which has being: where is the deceiver?"
    "We have found him," they cry ecstatically; "it is the senses! These senses, which are so immoral in other ways too, deceive us concerning the true world. Moral: let us free ourselves from the deception of the senses, from becoming, from history, from lies; history is nothing but faith in the senses, faith in lies. Moral: let us say No to all who have faith in the senses, to all the rest of mankind; they are all 'mob.' Let us be philosophers! Let us be mummies" Let us represent monotono-theism by adopting the expression of a gravedigger! And above all, away with the body, this wretched idée fixe of the senses, disfigured by all the fallacies of logic, refuted, even impossible, although it is impudent enough to behave as if it were real!"
    2With the highest respect, I except the name of Heraclitus. When the rest of the philosophic folk rejected the testimony of the senses because they showed multiplicity and change, he rejected their testimony because they showed things as if they had permanence and unity. Heraclitus too did the senses an injustice. They lie neither in the way the Eleatics believed, nor as he believed--they do not lie at all. What we make of their testimony, that alone introduces lies; for example, the lie of unity, the lie of thinghood, of substance, of permanence. "Reason" is the cause of our falsification of the testimony of the senses. Insofar as the senses show becoming, passing away, and change, they do not lie. But Heraclitus will remain eternally right with his assertion that being is an empty fiction. The "apparent" world is the only one: the "true" world is merely added by a lie.
    3And what magnificent instruments of observation we possess in our senses! This nose, for example, of which no philosopher has yet spoken with reverence and gratitude, is actually the most delicate instrument so far at our disposal: it is able to detect minimal differences of motion which even a spectroscope cannot detect. Today we possess science precisely to the extent to which we have decided to accept the testimony of the senses--to the extent to which we sharpen them further, arm them, and have learned to think them through. The rest is miscarriage and not-yet-science--in other words, metaphysics, theology, psychology, epistemology--or formal science, a doctrine of signs, such as logic and that applied logic which is called mathematics. In them reality is not encountered at all, not even as a problem--no more than the question of the value of such a sign-convention as logic.
    4The other idiosyncrasy of the philosophers is no less dangerous; it consists in confusing the last and the first. They place that which comes at the end--unfortunately! for it ought not to come at all!--namely, the "highest concepts," which means the most general, the emptiest concepts, the last smoke of evaporating reality, in the beginning, as the beginning. This again is nothing but their way of showing reverence: the higher may not grow out of the lower, may not have grown at all. Moral: whatever is of the first rank must be causa sui. Origin out of something else is considered an objection, a questioning of value. All the highest values are of the first rank; all the highest concepts, that which has being, the unconditional, the good, the true, the perfect--all these cannot have become and must therefore be causes. All these, moreover, cannot be unlike each other or in contradiction to each other. Thus they arrive at their stupendous concept, "God." That which is last, thinnest, and emptiest is put first, as the cause, as ens realissimum. Why did mankind have to take seriously the brain afflictions of sick web-spinners? They have paid dearly for it!
    5At long last, let us contrast the very different manner in which we conceive the problem of error and appearance. (I say "we" for politeness' sake.) Formerly, alteration, change, any becoming at all, were taken as proof of mere appearance, as an indication that there must be something which led us astray. Today, conversely, precisely insofar as the prejudice of reason forces us to posit unity, identity, permanence, substance, cause, thinghood, being, we see ourselves somehow caught in error, compelled into error. So certain are we, on the basis of rigorous examination, that this is where the error lies.
    It is no different in this case than with the movement of the sun: there our eye is the constant advocate of error, here it is our language. In its origin language belongs in the age of the most rudimentary form of psychology. We enter a realm of crude fetishism when we summon before consciousness the basic presuppositions of the metaphysics of language, in plain talk, the presuppositions of reason. Everywhere it sees a doer and doing; it believes in will as the cause; it believes in the ego, in the ego as being, in the ego as substance, and it projects this faith in the ego-substance upon all things--only thereby does it first create the concept of "thing." Everywhere "being" is projected by thought, pushed underneath, as the cause; the concept of being follows, and is a derivative of, the concept of ego. In the beginning there is that great calamity of an error that the will is something which is effective, that will is a capacity. Today we know that it is only a word.
    Very much later, in a world which was in a thousand ways more enlightened, philosophers, to their great surprise, became aware of the sureness, the subjective certainty, in our handling of the categories of reason: they concluded that these categories could not be derived from anything empirical--for everything empirical plainly contradicted them. Whence, then, were they derived?
    And in India, as in Greece, the same mistake was made: "We must once have been at home in a higher world (instead of a very much lower one, which would have been the truth); we must have been divine, for we have reason!" Indeed, nothing has yet possessed a more naive power of persuasion than the error concerning being, as it has been formulated by the Eleatics, for example. After all, every word and every sentence we say speak in its favor. Even the opponents of the Eleatics still succumbed to the seduction of their concept of being: Democritus, among others, when he invented his atom. "Reason" in language--oh, what an old deceptive female she is! I am afraid we are not rid of God because we still have faith in grammar.
    6It will be appreciated if I condense so essential and so new an insight into four theses. In that way I facilitate comprehension; in that way I provoke contradiction.
    First proposition. The reasons for which "this" world has been characterized as "apparent" are the very reasons which indicate its reality; any other kind of reality is absolutely indemonstrable.
    Second proposition. The criteria which have been bestowed on the "true being" of things are the criteria of not-being, of naught, the "true world" has been constructed out of contradiction to the actual world: indeed an apparent world, insofar as it is merely a moral-optical illusion.
    Third proposition. To invent fables about a world "other" than this one has no meaning at all, unless an instinct of slander, detraction, and suspicion against life has gained the upper hand in us: in that case, we avenge ourselves against life with a phantasmagoria of "another," a "better" life.
    Fourth proposition. Any distinction between a "true" and an "apparent" world--whether in the Christian manner or in the manner of Kant (in the end, an underhanded Christian)--is only a suggestion of decadence, a symptom of the decline of life. That the artist esteems appearance higher than reality is no objection to this proposition. For "appearance" in this case means reality once more, only by way of selection, reinforcement, and correction. The tragic artist is no pessimist: he is precisely the one who says Yes to everything questionable, even to the terrible--he is Dionysian.
