"Gentlemen, formerly savants were looked upon as a little group of amateurs and leisured people, maintained at the expense of the labouring classes, and performing a work of luxury for the amusement and distraction of the favourites of fortune. This narrow and unjust view which took so little into account, our services and devotion to truth, this prejudice, ended by disappearing when the development of science showed that Nature's laws were applicable to practical industry, and their effect was to replace the old traditional receipts and empirics by profitable rules founded on observation and experience. To-day who would dare to look upon science as a sterile amusement in presence the general increase of national and private riches which resulted from it?"
"Science is the real moral school; she teaches man the love and respect for the truth, without which all hope is chimerical."
"The most interesting of the services rendered by science is perhaps shown by comparing the servile and miserable condition of the popular masses in the past with their present state, already so much raised in dignity and comfort, without prejudice to the hopes which they are gradually realising."
"Is there still a statesman who doubts the services greater still that may be expected from this incessant progress?"
"Berthelot's agricultural station and laboratory were at , and here experiments on vegetable soils, the fixation of atmospheric nitrogen in soils by the agency of microbes, the action of electricity on the growth of plants, etc., were conducted. Berthelot states that twenty-five pounds of per annum per acre might be fixed by bacteria."
"During the siege of Paris, Berthelot was President of the Scientific Committee of National Defence, and was occupied in the manufacture of explosives, and in 1883 he published, in two volumes, his work, Sur la Force des Matieres Explosives... a valuable contribution to the science..."
"[O]f the numerous syntheses of Berthelot, or the building up of chemical compounds, many... were [previously] only obtained [naturally] through... life, either animal or vegetable."
"He formed by the action of the electric spark on a mixture of and ."
"In 1864 Berthelot began his great work on thermo-chemistry, and in 1879... published... Essai de Mécanique Chimique fondée sur la Thermo-chimie."
"His laws are... (1) The heat disengaged in any reaction is a measure of the chemical and physical work accomplished in the reaction. (2) The total thermal value of a reaction is dependent only on the initial and final states of the changing system. (3) "The Law of Maximum Work," or "the theorem of the necessity of reactions"... This law is the fundamental principle of Berthelot's thermo-chemistry: "The quantity of heat evolved in a reaction measures the sum of the physical and chemical changes which occur in that reaction"—"ce principe fournit la mesure des affinités chimiques.""
"He also formed by passing the vapour of and sulphuretted hydrogen over hot copper; and by the action of carbon monoxide on a hot solution of caustic potash, was produced, the formate yielding on distillation with ."
"Berthelot was justified by accomplished facts in stating that applied science has done more for mankind in the last three-quarters of a century than all the progress in all ages that preceded it."
"Berthelot believed in the possibility of wheat-growing and cattle-raising being superseded by the discovery of artificial substitutes for the necessaries of life. ...Berthelot's idea of the synthesis of substances that will take the place of wheat and meat is the most audacious flight of fancy... but it need not... be classed among the impossibilities."
"Berthelot was quite sure that physics and chemistry would soon solve the problem of aerial navigation, and he significantly remarked that when they do so " customhouses will fall of themselves.""
"His scientific labours were immense, and he completely revolutionized chemistry in more departments than one. He transformed agriculture; proved that inorganic and organic bodies obey the same laws; established "la théorie des affinités"; and invented thermo-chemistry."
"Probably the most important syntheses of his are the production of acetylene from carbon and hydrogen, and methane or marsh gas, by means of the well-known Berthelot's reaction; and of dynamical chemistry, his most important discovery is "the law of maximum work.""
"The first half of the nineteenth century was devoted to analytical chemistry—this being due to the great work of Berzelius. The second half, however, was the era of Berthelot or synthetical chemistry."
"Although glycerine was discovered by Scheele in 1779, and its formula established by Pelouze in 1836, it was not until 1854 that its true composition was known... [when] Berthelot... proved that it is an alcoholic compound capable of interacting with... acids as acetic and palmitic."
"He produced over a thousand memoirs, embracing every department of chemistry."
"In 1851, at the age of twenty-four, he entered the College de France, as préparateur of the lectures on chemistry (under Balard, the discoverer of bromine)."
"Although Wohler, in 1828, produced artificially, and Kolbe synthetized in 1845, Berthelot was undoubtedly the creator or founder of organic synthesis."
"[Berthelot] is not only a great chemist, but also a great philosopher. He possessed a universal spirit. His discovery of the synthesis of organic materials would be enough to immortalize his name. His work on explosive materials were also invaluable services..."
"Marcellin Berthelot... observed ants as a hobby. He published in 1886 under the title Science et philophie... several essays. One... "Les cités animales et leur évolution". ...He was convinced that the same instinct of sociability was active among human races and among animal ones. He considered the hypothesis of the social contract as a chimerical one. ...Ten years later, in another collection of essays... Science et morale... [h]e considered that it is more useful to compare human societies with ant colonies than with beehives, because while in the latter laws are uniform, in the former there is a place for individual intitiatives."
"Berthelot... says that alchemy rested partly on the industrial processes of the ancient Egyptians, partly on the speculative theories of the Greek philosophers, and partly on the mystical reveries of the Gnostics and the Alexandrians."
"[H]e was not only a great chemist, but a politician, philosopher, and author."
"In 1860 Berthelot's Chimie Organique fondée sur la Synthèse, was published. It was the first... based entirely on synthesis."
"A new conception of human destiny results from a profound knowledge of the universe and the physical and moral constitution of man, directed by the fundamental notions of universal solidarity between all classes and all nations."
"Gentlemen, since the first half of the century that has terminated, without going further back, the world has strangely altered. The men of my generation have seen come into play, beside and above the nature known since antiquity, if not an antithesis, a counter-nature... but a superior nature, and to some extent transcendent, where the power of indıvidual is centupled by the transformation of forces until then unknown or not understood, borrowed from light, magnetism, and electricity."
"According as the bonds uniting the peoples of the world together are multiplied and lightened by the progress of science and by unity of the doctrines and precepts that it deducts from facts, and imposes without violence and yet in a relentless manner to all convictions, these ideas have assumed a growing and more and more irresistible importance. They tend to become a purely human basis of nature, morality, and politics."
"Thus it is that the tangible utility of scientific results has made the public authorities understand that laboratory work should be encouraged and sustained, because it is economically a benefit to all and for the public health."
"Science carries its legitimate pretensions further. To-day it claims the material, intellectual, and moral direction of society. Under its impulse modern civilisation marches with an increasingly rapid stride."
"Hence the rôle of savants, as individuals and as a social class, has unceasingly developed in modern states. But our duties towards other men increase in the same ratio, and let it never be forgotten; let it proclaimed in this hall, in this palace of French science."
"Science is the benefactor of humanity."
"His methods were simple and direct. By means of the electric spark, and united to form ; or [acetylene was also obtained] by... [sparking] a mixture of hydrogen and ...or by... spark[ing] a mixture of hydrogen with vapour, or ."
"It not by reason of the egoistical satisfaction of our private vanity that the world-to-day pays homage to savants. No; it is because it knows that a savant really worthy of the name devotes a disinterested life to the great work of our epoch—I mean to say to the improvement, too slow, alas! for our taste, of the condition of every one, from the richest and happiest to the humble, the poor, and the suffering. That is what the public declared nine years ago in this same hall when honouring Pasteur. That is what my friend Chaplain has tried to express on the beautiful medal which the President of the Republic will presently offer me. I do not know if I have completely fulfilled noble ideal traced by the artist, but I have tried to make it object and end, the directing idea of my existence."
"Lewis has written that "man makes history." Althusser unleashes a pamphlet at him maintaining that such is not the case: "Ce sont les masses qui font l'histoire." I challenge anyone to find a social scientist outside the Marxist camp who can seriously pose a problem of this type."
"Into the 1960s the new Marx, the newly discovered Marx, was the Marx of the Paris Manuscripts. These are, as Marx once wrote to Engels in their later years, green, in contrast to the later grey of theory and the dull industrial culture of factory civilization which it sought to explain. Reading the young Marx was fun, more or less; reading Capital, in contrast, was hard work. Althusser sternly took on the duty of reading Capital, writing a very serious book called Reading Capital, and insisting that we should all read Capital seriously, in its multiple volumes, preferably in the original (Althusser and Balibar 1970). The early Marx was Marx before he was Marx, foreplay rather than the real action. Capital was taken to represent a new form of knowledge, building upon a significant epistemological break or rupture. We all became epistemologists. Nobody seemed to notice that this was a step away from practice, rather than towards it. But these were times of great seriosity, and high illusions, as well as very serious scholarship. Yet there was something important in this mission. Marx’s early writings give us the perspective of his laboratory. We can watch him thinking, and it can be an exhilarating experience. But his life’s work was Capital, and the architectonic of that work repays serious close reading. Rightly or wrongly, Marx had become convinced that the mode of presentation of this work was crucial; that there was a best way to explain capital, and that he had sorted it out. He was also convinced that capital was the privileged category, to be accessed via the logic of the commodity form. It did seem something of an irony that none, or few, of the Marxists had read Marx, because it was too hard. And this was part and parcel of the story of the fate of marxism. Engels, Kautsky (the pope of Marxism), then Lenin, and finally Stalin had reduced Marx’s theory to a series of axioms or platitudes about surplus value, historical and finally dialectical materialism. Marxists got by reciting these axioms in their daily denunciations of capitalism. Marxism had become its own caricature. Althusser blew the whistle on this state of affairs. After Althusser, it was inadmissible for Marxists to cut corners. They were now compelled to deal with their own theoretical heritage. A few clichés concerning the ubiquity of alienation and the need for revolution would no longer do."
"Althusser was not a charlatan. He himself really believed that he had discovered something significant—or was about to discover something significant—when his illness struck. It is not because he was mad that he was a mediocre philosopher; indeed, the recognition of his own intellectual mediocrity may have contributed to his depressions, and thence to his loss of sanity. If there is something humiliating about the Althusserian episode in intellectual history then, the humiliation is not his alone. He was a guru, complete with texts, a cult, and true believers; and he showed occasional insight into the pathos of his followers, noting that they imitated his "smallest gestures and inflections." Althusser's work and his life, with his drugs, his analysts, his self-pity, his illusions, and his moods, take on a curiously hermetic quality. He comes to resemble some minor medieval scholastic, desperately scrabbling around in categories of his own imagining. But even the most obscure theological speculation usually had as its goal something of significance. From Althusser's musings, however, nothing followed. They were not subject to proof and they had no intelligible worldly application, except as abstruse political apologetics. What does it say about modern academic life that such a figure can have trapped teachers and students for so long in the cage of his insane fictions, and traps them still?"
"Those who are in ideology believe themselves by definition outside ideology: one of the effects of ideology is the practical denegation of the ideological character of ideology by ideology: ideology never says, ‘I am ideological’. It is necessary to be outside ideology, i.e. in scientific knowledge, to be able to say: I am in ideology (a quite exceptional case) or (the general case): I was in ideology. As is well known, the accusation of being in ideology only applies to others, never to oneself (unless one is really a Spinozist or a Marxist, which, in this matter, is to be exactly the same thing). Which amounts to saying that ideology has no outside (for itself), but at the same time that it is nothing but outside (for science and reality)."
"All ideology hails or interpellates concrete individuals as concrete subjects, by the functioning of the category of the subject. ... ideology ‘acts’ or ‘functions’ in such a way that it ‘recruits’ subjects among the individuals (it recruits them all), or ‘transforms’ the individuals into subjects (it transforms them all) by that very precise operation which I have called interpellation or hailing, and which can be imagined along the lines of the most commonplace everyday police (or other) hailing: ‘Hey, you there!’"
"Marx compellingly proved it in Capital Volume Two, that no production is possible which does not allow for the reproduction of the material conditions of productions: the reproduction of the means of production."
"For you and for me, the category of the subject is a primary ‘obviousness’ (obviousnesses are always primary): it is clear that you and I are subjects (free, ethical, etc.). Like all obviousnesses, including those that make a word ‘name a thing’ or ‘have a meaning’ (therefore including the obviousness of the ‘transparency’ of language), the ‘obviousness’ that you and I are subjects – and that that does not cause any problems – is an ideological effect, the elementary ideological effect. It is indeed a peculiarity of ideology that it imposes (without appearing to do so, since these are ‘obviousnesses’) obviousnesses as obviousnesses."
"But someone is bound to question ... by what right I regard as Ideological State Apparatuses, institutions which for the most part do not possess public status, but are quite simply private institutions. As a conscious Marxist, Gramsci already forestalled this objection in one sentence. The distinction between the public and the private is a distinction internal to bourgeois law, and valid in the (subordinate) domains in which bourgeois law exercises its ‘authority’. The domain of the State escapes it because the latter is ‘above the law’: the State, which is the State of the ruling class, is neither public nor private; on the contrary, it is the precondition for any distinction between public and private. The same thing can be said from the starting-point of our State Ideological Apparatuses. It is unimportant whether the institutions in which they are realized are ‘public’ or ‘private’. What matters is how they function."
"While speaking in ideology, and from within ideology we have to outline a discourse which tries to break with ideology, in order to dare to be the beginning of a scientific (i.e. subject-less) discourse on ideology."
"What do children learn at school? They go varying distances in their studies, but at any rate they learn to read, to write and to add - i.e. a number of techniques, and a number of other things as well, including elements (which may be rudimentary or on the contrary thoroughgoing) of scientific' or 'literary culture', which are directly useful in the different jobs in production (one instruction for manual workers, another for technicians, a third for engineers, a final one for higher management, etc.). Thus they learn 'know-how'."
"The reproduction of labour power thus reveals as its sine qua non not only the reproduction of its ‘skills’ but also the reproduction of its subjection to the ruling ideology. ... It is in the forms and under the forms of ideological subjection that provision is made for the reproduction of the skills of labour power."
"To be a Communist is to be a partisan and artisan of Marxism-Leninist philosophy: of dialectical materialism."
"The proletariat must seize state power in order to destroy the existing bourgeois state apparatus and, in a first phase, replace it with a quite different, proletarian, state apparatus, then in later phases set in motion a radical process, that of the destruction of the state."
"The sciences we are familiar with have been installed in a number of great 'continents'. Before Marx, two such continents had been opened up to scientific knowledge: the continent of Mathematics and the continent of Physics. The first by the Greeks (Thales), the second by Galileo. Marx opened up a third continent to scientific knowledge: the continent of History."
"Class instinct is subjective and spontaneous. ... To arrive at proletarian class positions, the class instinct of proletarians only needs to be educated; the class instinct of the petty bourgeoisie, and hence of intellectuals, has, on the contrary, to be revolutionized."
