"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 order to determine whether or not one sentence is a consequence of another, no reference need be made to the meaning of the sentences. The mere statement of the truth-values is certainly too little; but the statement of the meaning is, on the other hand, too much. It is sufficient that the syntactical design of the sentences be given."
"If someone wishes to speak in his language about a new kind of entities, he has to introduce a system of new ways of speaking, subject to new rules; we shall call this procedure the construction of a linguistic framework for the new entities in question."
"According to this view, the sentences of metaphysics are pseudo-sentences which on logical analysis are proved to be either empty phrases or phrases which violate the rules of syntax. Of the so-called philosophical problems, the only questions which have any meaning are those of the logic of science. To share this view is to substitute logical syntax for philosophy."
"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."
"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."
"Logic is not concerned with human behavior in the same sense that physiology, psychology, and social sciences are concerned with it. These sciences formulate laws or universal statements which have as their subject matter human activities as processes in time. Logic, on the contrary, is concerned with relations between factual sentences (or thoughts). If logic ever discusses the truth of factual sentences it does so only conditionally, somewhat as follows: if such-and-such a sentence is true, then such-and-such another sentence is true. Logic itself does not decide whether the first sentence is true, but surrenders that question to one or the other of the empirical sciences."
"In science there are no 'depths'; there is surface everywhere."
"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."
"Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements."
"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."
"Logic is the last scientific ingredient of Philosophy; its extraction leaves behind only a confusion of non-scientific, pseudo problems."
"The main purpose of this book is the development of a new method for the semantical analysis of meaning, that is, a new method for analyzing and describing the meanings of linguistic expressions. This method, called the method of extension and intension, is developed by modifying and extending certain customary concepts, especially those of class and property. The method will be contrasted with various other semantical methods used in traditional philosophy or by contemporary authors."
"Eduard Pestel recalled that the Club of Rome’s founder, Aurelio Peccei, was tremendously impressed “by the fact that all computer runs exhibited—sooner or later at some point in time during the next century—a collapse mode regardless of any ‘technological fixes’ employed,” and that Peccei “obviously saw his fears confirmed.”"
"Mesarovic and Pestel are critical of the Forrester-Meadows world view, which is that of a homogeneous system with a fully predetermined evolution in time once the initial conditions are specified"
"Mihajlo Masarovic and Eduard Pestel (1974) attempted a radical innovation by developing complex models that combined demographic projections with economic, social, environmental, and political trends, with the objective of revealing that the population predicted by the UN would necessarily lead to an an explosion of the world system during the 21st century, causing an increase in mortality and a rapid population decline."
"Mihajlo Mesarovic and Eduard Pestel have made a deliberate attempt to gain approbation from the skeptical segment of the intellectual community and to disassociate their work from that of Forrester and Meadows."
"Eduard Pestel is also known... for his blunt pleas to make global modelling relevant to decision makers."
"Pestel was a very forceful person and quickly saw the power of system dynamics."
"Our world model was built specifically to investigate five major trends of global concern – accelerating industrialization, rapid population growth, widespread malnutrition, depletion of nonrenewable resources, and a deteriorating environment. The model we have constructed is, like every model, imperfect, oversimplified, and unfinished... Our conclusions are : (1.) If the present growth trends in world population, industrialization, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity..."
"The value of global modelling has been severely restricted by poor appreciation of the constraints under which governments and politicians operate. Equally, the value of governments and politicians has been severely restricted by largely ignoring the very real but less immediate problems tackled by modellers."
"Social costs... are all direct and indirect losses sustained by third persons or the general public as a result of unrestrained economic activities."
"To ignore social costs because they require an evaluation by society... and to leave social losses out of account because they are 'external' and 'non-economic' in character, would be equivalent to attributing no or ‘zero’ value to all social damages which is no less arbitrary and subjective a judgement than any positive or negative evaluation of social costs."
"They (social costs) are damages or diseconomies sustained by the economy in general, which under different institutional conditions could be avoided. [. . .] if these costs were inevitable under any kind of institutional arrangement they would not really present a special theoretical problem. [. . .] to reveal their origin, the study of social costs must always be an institutional analysis. Such an analysis raises inevitably the question of institutional reform and policy."
"Had there been a computer in 1872... it would probably have predicted that there would be so many horse-drawn vehicles that it would be impossible to clear up all the manure."
"Capitalism must be regarded as an economy of unpaid costs, ‘unpaid’ in so far as a substantial portion of the actual costs of production remains unaccounted for in entrepreneurial outlays; instead they are shifted to, and ultimately borne by, third persons or by the community as a whole."
"Whenever social costs are shifted onto economically and politically weaker sections of society without compensation, a redistribution of the costs of production, hence real income is involved."
"K. William Kapp's book "The Social Costs of Private Enterprise" was one of the first economic treatise that called attention to the ecological and social external costs of the market economy. His book is considered one of the origins of and a foundation for ecological economics."
"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.)"
"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 …)."
"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."
"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."
"Should you seek might, power, false honor, excess — seek that we would work for you to provide your temporal advantages — 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 — want to learn to make mankind more clever, better, free and happy — then be thrice welcomed by us."
"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 — 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 — there alone one recognizes, believes, feels what an honor, what a joy it is to be a human being."
"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."
"Do you realize sufficiently what it means to rule—to 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?"
"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."
"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. […] The whole earth becomes a garden, and nature has at last completed her day’s 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, mankind’s 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."
"One must at least know what the lies are."
"The Third Reich coined only a very small number of the words in its language, perhaps - indeed probably - none at all. . . But it changes the value of words and the frequency of their occurrence, it makes common property out of what was previously the preserve of an individual or a tiny group, it commandeers for the party that which was previously common property and in the process steeps words and groups of words and sentence structures with its poison."
"Never - never in my whole life - has my head spun as much from a book as it did with Rosenberg’s Myth. Not because his writings were exceptionally profound, difficult to comprehend or emotionally overwhelming, but because Clemens hammered on my head with the book for minutes on end. (Clemens and Weser were the principal torturers of the Jews in Dresden, and they were generally differentiated as the Hitter and the Spitter.) ‘How dare a Jewish pig like you presume to read a book of this kind?’ Clemens yelled. To him it seemed like the desecration of a consecrated wafer. ‘How dare you have a book here from the lending library?’ Only the fact that the volume had demonstrably been borrowed in the name of my Aryan wife, and, moreover, that the sheet of notes which accompanied it was torn up without being deciphered, saved me at the time from the concentration camp."
"No, the most powerful influence was exerted neither by individual speeches nor by articles or flyers, posters or flags; it was not achieved by things which one had to absorb by conscious thought or conscious emotions. Instead Nazism permeated the flesh and blood of the people through single words, idioms and sentence structures which were imposed on them in a million repetitions and taken on board mechanically and unconsciously. … Language does not simply write and think for me, it also increasingly dictates my feelings and governs my entire spiritual being the more unquestioningly and unconsciously I abandon myself to it. And what happens if the cultivated language is made up of poisonous elements or has been made the bearer of poisons? Words can be like tiny doses of arsenic: they are swallowed unnoticed, appear to have no effect, and then after a little time the toxic reaction sets in after all."
"On countless occasions during my spell as an assistant in Naples I heard people say about some newspaper or other: è pagato, it’s paid for, it lies for its client, and then on the following day these very same people who had cried pagato were absolutely convinced by some obviously bogus piece of news in the same paper. Because it was printed in such bold type, and because the other people believed it. … I also know that a part of every intellectual’s soul belongs to the people, that all my awareness of being lied to, and my critical attentiveness, are of no avail when it comes to it: at some point the printed lie will get the better of me when it attacks from all sides and is queried by fewer and fewer around me and finally by no one at all."
"Anyone who took their Catholic faith seriously stood alongside the Jews in mutual, mortal conflict with Hitler."
"Individuals did what they could both to preserve memories of their peoples and record the horrors of the present. At the risk of his life, a Muslim librarian in Sarajevo smuggled out a rare illuminated Jewish manuscript from the fourteenth century from the National Museum of Bosnia and Herzegovina to save it from the Nazis. In Vilna Jewish scholars who were forced by the Nazis to catalogue a vast hoard of seized Jewish documents smuggled out what they could and hid them under floorboards and in walls. Photographers defied Nazi rules to take and preserve pictures of ghettos and concentration camps. When the Nazis came to power in Germany in 1933, Victor Klemperer, a professor of Romance languages in Dresden, decided that he would continue writing his diary. He makes frequent reference to his health, repeatedly predicting that he was not long for this world. (He died in 1960 at the age of seventy-nine.) Klemperer said of himself that he was not heroic, but to write a record, as he did, of the growing Nazi control over German society and the regime’s many crimes, including the Second World War and the Holocaust, was an act of great courage. ‘I shall go on writing,’ he recorded in 1942. ‘That is my heroism. I will bear witness, precise witness!’ Although the Nazis counted him as Jewish despite the fact that his family had converted to Christianity, he was spared because he was married to an Aryan woman. As the restrictions tightened around him, she was still allowed to travel freely and bravely smuggled the pages of the diary out of the special house for mixed marriages where they were obliged to live. Equally bravely, a woman doctor friend hid the material until the war ended."
"But there is no vox populi, only voci populi."
"For my own part I have never been able to understand how he [Hitler] was capable, with his unmelodious and raucous voice, with his crude, often un-Germanically constructed sentences, and with a conspicuous rhetoric entirely at odds with the character of the German language, of winning over the masses with his speeches, of holding their attention and subjugating them for such appalling lengths of time."
"Only a year after the collapse of the Third Reich a strangely conclusive piece of evidence can be advanced to support the claim that "fanatical", this key National Socialist term, never really had the sting taken out of it by excessive use. For although scraps of the LTI surface all over the place in contemporary language, "fanatical" has disappeared. From this one can safely conclude that either consciously or subconsciously people remained aware of the real facts of the case all through those twelve years, namely, that a confused state of mind, equally close to sickness and criminality, was for twelve years [of Nazi rule] held to be the greatest virtue."
"The monetary system we have inherited is more than 2,000 years old."
