"When I met Wittgenstein, I saw that Schlick's warnings were fully justified. But his behavior was not caused by any arrogance. In general, he was of a sympathetic temperament and very kind; but he was hypersensitive and easily irritated. Whatever he said was always interesting and stimulating and the way in which he expressed it was often fascinating. His point of view and his attitude toward people and problems, even theoretical problems, were much more similar to those of a creative artist than to those of a scientist; one might almost say, similar to those of a religious prophet or a seer. When he started to formulate his view on some specific problem, we often felt the internal struggle that occurred in him at that very moment, a struggle by which he tried to penetrate from darkness to light under an intense and painful strain, which was even visible on his most expressive face. When finally, sometimes after a prolonged arduous effort, his answers came forth, his statement stood before us like a newly created piece of art or a divine revelation. Not that he asserted his views dogmatically ⌠But the impression he made on us was as if insight came to him as through divine inspiration, so that we could not help feeling that any sober rational comment of analysis of it would be a profanation."
"If we compare. e.g. the systems of classical mathematics and of intuitionistic mathematics, we find that the first is much simpler and technically more efficient, while the second is more safe from surprising occurences, e.g. contradictions. At the present time, any estimation of the degree of safety of the system of classical mathematics, in other words, the degree of plausibility of its principles, is rather subjective. The majority of mathematicians seem to regard this degree as sufficiently high for all practical purposes and therefore prefer the application of classical mathematics to that of intuitionistic mathematics. The latter has not, so far as I know, been seriously applied in physics by anybody."
"Philosophy is to be replaced by the logic of science -- that is to say, by the logical analysis of the concepts and sentences of the sciences, for the logic of science is nothing other than the logical syntax of the language of science."
"The function of logical analysis is to analyse all knowledge, all assertions of science and of everyday life, in order to make clear the sense of each such assertion and the connections between them. One of the principal tasks of the logical analysis of a given proposition is to find out the method of verification for that proposition."
"After the new forms are introduced into the language, it is possible to formulate with their help internal questions and possible answers to them. A question of this kind may be either empirical or logical; accordingly a true answer is either factually true or analytic."
"By the logical syntax of a language, we mean the formal theory of the linguistic forms of that language -- the systematic statement of the formal rules which govern it together with the development of the consequences which follow from these rules. A theory, a rule, a definition, or the like is to be called formal when no reference is made in it either to the meaning of the symbols (for examples, the words) or to the sense of the expressions (e.g. the sentences), but simply and solely to the kinds and order of the symbols from which the expressions are constructed."
"In science there are no 'depths'; there is surface everywhere."
"In this time, when the games and abuses of secret societies were without end, I wanted to make use of this human weakness for a real and worthy goal, the welfare of mankind.⌠I wanted what the heads of the ecclesiastical and secular powers should do and want by virtue of their offices."
"Wishaupt seems to be an enthusiastic Philanthropist. He is among those (as you know the excellent [Richard] Price and Priestley also are) who believe in the indefinite perfectibility of man. He thinks he may in time be rendered so perfect that he will be able to govern himself in every circumstance so as to injure none, to do all the good he can, to leave government no occasion to exercise their powers over him, & of course to render political government useless."
"As Wishaupt lived under the tyranny of a despot & priests, he knew that caution was necessary even in spreading information, & the principles of pure morality.⌠He proposed to initiate new members into his body by gradations proportioned to his fears of the thunderbolts of tyranny. This has given an air of mystery to his views, was the foundation of his banishment, the subversion of the masonic order, & is the colour for the ravings against him of Robinson, Barruel & Morse, whose real fears are that the craft would be endangered by the spreading of information, reason, & natural morality among men."
"This first stage of the life of the whole race is savagery, raw nature:⌠a condition in which man enjoys the most exquisite goods, equality and freedom, in full abundance, and would also enjoy them forever, if he would follow the hint of nature and understand the art of not abusing his powers and preventing the outbreak of his excessive passions."
"It has been claimed that Dr. Weishaupt was an atheist, a Cabalistic magician, a rationalist, a mystic; a democrat, a socialist, an anarchist, a fascist; a Machiavellian amoralist, an alchemist, a totalitarian and an "enthusiastic philanthropist." (The last was the verdict of Thomas Jefferson, by the way.)"
"Since the number of men is large but the earthly realm is not inexhaustible, one man can no longer profit from the labour of twenty. Moderation, contentment, and frugality must become the general morals of mankind. [âŚ] The whole earth becomes a garden, and nature has at last completed her dayâs work here below, bringing permanent enlightenment, peace, and felicity together with the greatest possible number of men : she has anointed every man as his own judge, priest, and king; has turned the often-ridiculed tale of the golden age, mankindâs favorite idea of old, into a reality by discreetly removing the eternal inequality of wealth, which has been ineffectively combated by all lawgivers and has always has crept back in, and which is the source of the decay of all nations, and the root of servitude, tyranny, and disunity among men, of venality and moral corruption, making it forever impossible through the excessive growth of the human population."
"I myself brought Deism no more to Bavaria than to Rome or Italy. I found it there already; and I shall give the reasons below, just why in the most fanatical countries, and more under Catholicism than Protestantism, this sort of person is found in such a measure and multitude."
"In the stage of manhood alone does the human race first appear in his dignity; only there are his principles fixed, his connections appropriate, he sees the full circumference of his sphere; there alone â after we have already learned through many detours, through long, repeated, sad experiences, what a calamity it is to arrogate the rights of others, to raise oneself over others through mere external advantages, to use his size to the detriment of others â there alone one recognizes, believes, feels what an honor, what a joy it is to be a human being."
"Do you realize sufficiently what it means to ruleâto rule in a secret society? Not only over the lesser or more important of the populace, but over the best of men, over men of all ranks, nations, and religions, to rule without external force, to unite them indissolubly, to breathe one spirit and soul into them, men distributed over all parts of the world?"
"The one safe generalization one can make is that Weishaupt's intent to maintain secrecy has worked; no two students of Illuminology have ever agreed totally about what the "inner secret" or purpose of the order actually was (or is âŚ)."
"Should you seek might, power, false honor, excess â seek that we would work for you to provide your temporal advantages â we will bring you as close to the throne as you wish, and then turn you over to the consequences of your folly, but our inner sanctuary remains closed to such. But should you want to learn wisdom â want to learn to make mankind more clever, better, free and happy â then be thrice welcomed by us."
"And so, from this day forth, we want all the more to let our thoughts revolve around and hover over Socrates and Christ at all times, openly taking pride that they are more alive for us than all those living today and that we listen to and love them as we do none of the living."
"Socrates and Christ speak to us everlastingly of mankind. ⌠It belongs to the great, to the greatest men to say how things are with mankind, how they stand in its innerness and which way it is going; it belongs to Socrates and Christ. These absolutely extraordinary, eternally alive people penetrate to the groundless depth of human nature and understand the speech of ordinary people, of those who are scarcely alive from one day to the next."
"The difference between Christ and the other prophets is threefold: 1. Unlike the other prophets, he has no connection with politics and is not a people's tribune. In the Gospels, we find temporal circumstances only as background, Christ having no relationship to them at all. He kept his thoughts unmuddled by the world â "Get thee behind me, Satan!" â he was and remained truly free of the world. 2. He preaches no religious superficialities whatsoever, nothing at all of worship, nothing of God; he is truly godless. 3. Neither for earth nor heaven does he preach any coming kingdom. "But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you" (Mt. 6:33). The kingdom, however, is nothing that is to come; it is here, it is within you (Lk. 17:21). It is the Spirit of innerness as it is alive in him, the truly blessed man; it is the essence, ever being and never changing. It is also the essence of this our life, not merely an appendix granted it by some other essence, for which we would have to fulfill certain conditions."
"Christ, with whom the multitude could not deal other than by making him into God Himself, thus enabling itself to venerate as God him whom they had loathed as man."
"Great, strong, spiritual love â which is always at the same time a genuine, unsentimental love of man â cannot be without wrath. ⌠Anger can no more be separated from love than flame and heat can from fire. Love and anger are a single fire of the Spirit."
"Men are forever doing two things at the same time: acting egoistically and talking moralistically."
"In point of fact there are two kinds sorts of mysticism, differing from one another as the ranting of drunkards from the language of illumined spirits. There is the muddled, stammering mysticism, and there is the mysticism luminous with truly ultimate ideas. On the one hand there are the empty dimness and darkness, the barren, chilling sentimentalism and mental debauchery, the foolishly grimacing but rigid phantasms of the Cabbala, of occultism, mysteriosophy and theosophy. We cannot draw too sharp a dividing line between these and the brightness, the simple sincerity, and healthy, rejuvenating strength of genuine mysticism, which takes the most precious gems from philosophy's treasure chest and displays them in the beauty of its own setting. Mysticism is in complete accord with the result, with the sum of philosophy. In fact, mysticism is precisely the sum and the soul of philosophy, in the form of that rapturous, passionate outpouring of love.... We are concerned with an understanding of this serious mysticism, and its meaning could be stated in three words... godlessness... freedom from the world... blessedness of soul."
"In mysticism, everything is thrown at us directly, without discursiveness and ratiocination, as if it were a matter of course, and we are challenged to follow an unrestrainable will to love, arising out of a tremendously agitated, indiscriminate feeling. ⌠Mystics willârather than knowâtheir thoughts. ⌠Mysticism witnesses nothing but love; mysticism is nothing but love. ⌠Art shows how it loves, philosophy what it loves; mysticism knows only that it loves."
"From the midst of the flat plain of human reason, there arises the terrible, fire-spewing mountain of genius."
"The usual judgments are judgments of interest and they tell us less about the nature of the person judged than about the interest of the one who judges."
"Christ ⌠made the blood of the specialists and leading spirits, the representatives of the people boil with his battle-cry: "I", "I", "I"! and provoked the enraged counterblast: We, We, We!"
"The question about âgood originsâ becomes the crux for enlightenment. It becomes more and more clear that this idea of origin has not a temporal but a Utopian reference. The Good is still nowhere to be found, except in the wishful human spirit."
"From the start, the bourgeois-positivistic fraction of enlightenment was uncomfortable about the unpredictable, subversive dimensions of the new category, the unconscious. With it, the motif of critical self-reflection was introduced into civilization in a way that could not please those who held themselves to be the representatives of civilization. If every ego is underlaid by an unconscious, then that is the end of the self-satisfaction of a consciousness that thinks it knows itself, and thus knows how to value itself. The âunconsciousâ touched on the cultural narcissism of all social classes."
"Rousseau diagnosed a total degeneration, a complete fall of humanity from âNatureâ in the society of the eighteenth century. All spontaneity had been denaturalized through convention, all naĂŻvetĂŠ had been replaced by finesse, all sincerity had been glossed over by facades of social intercourse, etc."
"Bourgeois morality tries to maintain an illusion of altruism, whereas in all other areas bourgeois thinking has long since assumed a theoretical as well as an economic egocentrism."
"Since the eighteenth century, enlighteners have concerned themselvesâas defenders of âtrue morality,â whatever that may beâwith the morality of those who rule. ⌠The moralism in the bourgeois sense of decency put aristocratically refined immoralism into the position of the politically accused. ⌠But bourgeois thinking all too naively assumes it is possible to subordinate political power to moral concepts. It does not anticipate that one day, when it has itself come to power, it will end up in the same ambivalence. It has not yet realized that it is only a small step from taking moral offense to respectable hypocrisy."
"The evidence introduced for political pessimism; the criminal, the lunatic, and the asocial individual, in a word, the second-rate citizen âthese are not by nature as one finds them now but have been made so by society. It is said that they have never had a chance to be as they would be according to their nature, but were forced into the situation in which they find themselves through poverty, coercion, and ignorance. They are victims of society. This defense against political pessimism regarding human nature is at first convincing. It possesses the superiority of dialectical thinking over positivistic thinking. It transforms moral states and qualities into processes. Brutal people do not âexist,â only their brutalization; criminality does not âexist,â only criminalization; stupidity does not âexist,â only stupefaction; self-seeking does not âexist,â only training in egoism; there are no second-rate citizens, only victims of patronization. What political positivism takes to be nature is in reality falsified nature: the suppression of opportunity for human beings. Rousseau knew of two aids who could illustrate his point of view, two classes of human beings who lived before civilization and, consequently, before perversion: the noble savage and the child. Enlightenment literature develops two of its most intimate passions around these two figures: ethnology and pedagogy."
"There probably has to be a worldview for practical men who must be strong enough to get their hands dirty in political practice without getting dirty themselves, and even if they do, who cares? And a second worldview for youths, simpletons, women, and sensitive souls, for whom âpurityâ is just the right thing. One could call it a division of labor among temperaments."
"From this moment on, the child becomes a political objectâto a certain extent, the living security deposit of enlightenment. The child is the ânoble savageâ in oneâs own house. Through appropriate education care must be taken in the future that innocent children are not made into the same artificial social cripples the previous system produced. Children are already what the new bourgeois humans believe they want to become."
"When conservatives and reactionaries refer to âNatureâ to justify their assertions about the inferiority of woman, the lesser capacities of dark races, the innate intelligence of children from the upper social strata, and the sickness of homosexuality, they have usurped naturalism. It remains the task of critique to refute this. Ultimately critique must at least be able to show that what âNatureâ gives us has to be recognized as neutral and nontendentious so that every value judgment and every tendency can without doubt be understood as a cultural phenomenon. Even if Rousseauâs âgood Natureâ has been discredited, he has at least taught us not to accept âbad Natureâ as an excuse for social oppression."
"The gesture of exposure characterizes the style of argumentation of ideology critique, from the critique of religion in the eighteenth century to the critique of fascism in the twentieth. Everywhere, one discovers extrarational mechanisms of opinion: interests, passions, fixations, illusions. That helps a bit to mitigate the scandalous contradiction between the postulated unity of truth and the factual plurality of opinionsâsince it cannot be eliminated. Under these assumptions, a true theory would be one that not only grounds its own theses best, but also knows how to defuse all significant and persistent counterpositions through ideology critique."
"The argumentum ad personam, is strongly disapproved of in the âacademic community.â Respectable critique meets its opponent in its best form; critique honors itself when it overwhelms its rival in the full armor of its rationality."
"For as long as possible, the learned collegium has tried to defend its integrity against the close combat of ideologico-critical exposures. Do not unmask, lest you yourself be unmasked could be the unspoken rule. It is no accident that the great representatives of critiqueâthe French moralists, the Encyclopedists, the socialists, and especially Heine, Marx, Nietzsche, and Freudâremain outsiders to the scholarly domain. In all of them there is a satirical, polemical component that can scarcely be hidden under the mask of scholarly respectability. These signals of a holy nonseriousness, which remains one of the sure indexes of truth, can be employed as signposts to the critique of cynical reason."
"⌠undermined by the need for seriousness ..."
"Ideologically, the reference to âNatureâ is always significant because it produces an artificial naĂŻvetĂŠ and ends up as voluntary naĂŻvetĂŠ. It covers up the human contribution and avers that things are by nature, and from their origins, in that âorderâ in which our representations, which are always influenced by âinterests,â depict them. The rudiments for ideologies of order are hidden in all naturalisms."
"Because there are no truths that can be taken possession of without a struggle, and because all knowledge must choose a place in the configuration of hegemonic and oppositional forces, the means of establishing knowledge seem to be almost more important than the knowledge itself. ⌠The demand to universalize the rational draws it into the vortex of politics, pedagogy, and propaganda. With this, enlightenment consciously represses the harsh realism of older precepts of wisdom, for which there was no question that the masses are foolish and that reason is to be found only among the few. Modern elitism has to encode itself democratically."
"âPhilosophicalâ ideology critique is truly the heir of a great satirical tradition, in which the motif of unmasking, exposing, baring has served for aeons now as a weapon. But modern ideology critiqueâaccording to our thesis has ominously cut itself off from the powerful traditions of laughter in satirical knowledge."
"Ideology critique raises a claim that it shares with hermeneutics, namely, the claim to understand an âauthorâ better than he understands himself. What at first sounds arrogant about this claim can be methodologically justified. Others often really do perceive things about me that escape my attentionâand conversely. They possess the advantage of distance, which I can profit from only retrospectively through dialogic mirroring. This, of course, would presuppose a functioning dialogue, which is precisely what does not take place in the process of ideology critique. An ideology critique that does not clearly accept its identity as satire can, however, easily be transformed from an instrument in the search for truth into one of dogmatism. All too often, it interferes with the capacity for dialogue instead of opening up new paths for it."
"Ideology critique, having become respectable, imitates surgical procedure: ⌠The opponent is cut open in front of everyone, until the mechanism of his error is laid bare. ⌠Ideology critique is now interested not in winning over the vivisected opponent but in focusing on the âcorpse,â the critical extract of its ideas. ⌠Those who previously did not want to engage in enlightenment will want to do so even less now that they have been dissected and exposed by the opponent."
"Zynismus ist das aufgeklärte falsche BewuĂtsein, an dem Aufklärung zugleich erfolgreich und vergeblich gearbeitet hat. Es hat seine Aufklärungselektion gelernt, aber nicht vollzogen und wohl nicht vollziehen kĂśnnen. Gutsituiert und miserabel zugleich fĂźhlt sich dieses BewuĂtsein von keiner Ideologiekritik mehr betroffen; seine Falschheit ist bereits reflexiv gefedert."
"The only loyalty to enlightenment consists in disloyalty. This can be partly understood from the position of its heirs, who look back on the âheroicâ times and are necessarily more skeptical of the results. To be an heir always carries a certain âstatus cynicismâ with it, as is well known from stories about the inheritance of family capital."
"Enlightenment does nothing more than eavesdrop on likely wolves in their dressing rooms, where they put on and take off their sheepâs clothing."
