"A good means to discovery is to take away certain parts of a system to find out how the rest behaves."
"It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people's attention and give them a livelier idea of God than do the often ill-applied examples of his wrath."
"A book which, above all others in the world, should be forbidden, is a catalogue of forbidden books."
"Where the frontier of science once was is now the centre."
"All mathematical laws which we find in Nature are always suspect to me, in spite of their beauty. They give me no pleasure. They are merely auxiliaries. At close range it is all not true."
"One might call habit a moral friction: something that prevents the mind from gliding over things but connects it with them and makes it hard for it to free itself from them."
"Comedy is in act superior to tragedy and humourous reasoning superior to grandiloquent reasoning."
"You cannot conquer an awakened people. You cannot Prussianize Belgium and France. You cannot eradicate the teachings of Marx and Engels from the minds of hundreds of thousands of German Socialists. Surely they would find some way of uniting in spirit and in deed with the comrades of other nations in case of such an invasion on the part of a government which they had always understood and denounced."
"Today in Korea—in Southeast Asia—in Latin America and the West Indies, in the Middle East—in Africa, one sees tens of millions of long oppressed colonial peoples surging toward freedom. What courage—what sacrifice—what determination never to rest until victory!...And arrayed against them, the combined powers of the so-called Free West, headed by the greedy, profit-hungry, war-minded industrialists and financial barons of our America. The illusion of an “American Century” blinds them for the immediate present to the clear fact that civilization has passed them by—that we now live in a people’s century—that the star shines brightly in the East of Europe and of the world. Colonial peoples today look to the Soviet Socialist Republics...One reverently speaks of Marx, Engels, Lenin and Stalin—the shapers of humanity’s richest present and future."
"Engels's analysis has faced criticism in the twentieth century, both for its anthropological inaccuracy and for its theoretical confusion. Simone de Beauvoir found the materialist position inadequate to describe the nature of female subordination. "Historical materialism takes for granted facts that call for explanations.... It cannot provide solutions for the problems we have raised, because these concern the whole man and not that abstraction: Homo economicus." Simone de Beauvoir argued that woman's oppression is at bottom not based on economic factors, for "if the human consciousness had not included the original category of the Other and an original aspiration to dominate the Other, the invention of the bronze tool could not have caused the oppression of woman." More recently Ann Lane has attacked not materialism but Engels's inconsistency in applying it. She has argued that Engels mistakenly believed "that the responsibilities of home and family, and the economic ties that bind them together, are not an important part of what establishes their cohesion, that society can remove a vital function of an institution in order to perfect it. Socialist society will strip the family of most of its traditional jobs, but the family itself, in its pristine state, untouched by history or reality, shall remain.""
"Friedrich Engels once said: “Bourgeois society stands at the crossroads, either transition to socialism or regression into barbarism.” What does “regression into barbarism” mean to our lofty European civilization? Until now, we have all probably read and repeated these words thoughtlessly, without suspecting their fearsome seriousness. A look around us at this moment shows what the regression of bourgeois society into barbarism means. This world war is a regression into barbarism. The triumph of imperialism leads to the annihilation of civilization."
"Engels always considered himself a junior partner, and so, without doubt, he was. But that does not lessen his role. Had he not been the junior partner, much for which his senior partner is known would not have been done."
"That the Materialistic Socialists will improve H. [History] for the poor. Their best writer, Engels, made known the errors and the horrors of our Factory System."
"The vision that impels feminists to action was the vision of the Grandmothers' society, the society that was captured in the words of the sixteenth-century explorer Peter Martyr nearly five hundred years ago. It is the same vision repeated over and over by radical thinkers of Europe and America, from François Villon to John Locke, from William Shakespeare to Thomas Jefferson, from Karl Marx to Friedrich Engels, from Benito Juarez to Martin Luther King, from Elizabeth Cady Stanton to Judy Grahn, from Harriet Tubman to Audre Lorde, from Emma Goldman to Bella Abzug, from Malinalli to Cherrie Moraga, and from Iyatiku to me. That vision as Martyr told it is of a country where there are "no soldiers, no gendarmes or police, no nobles, kings, regents, prefects, or judges, no prisons, no lawsuits... All are equal and free.""
"From the moment when labour can no longer be converted into capital, money, or rent, into a social power capable of being monopolized, i.e., from the moment when individual property can no longer be transformed into bourgeois property, into capital, from that moment, you say individuality vanishes."
"Diese aus dem gegenseitigen Neid und der Habgier der Kaufleute entstandene Nationalökonomie oder Bereicherungswissenschaft trägt das Gepräge der ekelhaftesten Selbstsucht auf der Stirne."
"Since the communists cannot enter upon the decisive struggle between themselves and the bourgeoisie until the bourgeoisie is in power, it follows that it is in the interest of the communists to help the bourgeoisie to power as soon as possible in order the sooner to be able to overthrow it."
"Democratic socialists are either proletarians who are not yet sufficiently clear about the conditions of the liberation of their class, or they are representatives of the petty bourgeoisie, a class which, prior to the achievement of democracy and the socialist measures to which it gives rise, has many interests in common with the proletariat. It follows that, in moments of action, the communists will have to come to an understanding with these democratic socialists, and in general to follow as far as possible a common policy with them – provided that these socialists do not enter into the service of the ruling bourgeoisie and attack the communists. It is clear that this form of co-operation in action does not exclude the discussion of differences."
"Some propose mere welfare measures – while others come forward with grandiose systems of reform which, under the pretense of re-organizing society, are in fact intended to preserve the foundations, and hence the life, of existing society. Communists must unremittingly struggle against these bourgeois socialists because they work for the enemies of communists and protect the society which communists aim to overthrow."
"All religions so far have been the expression of historical stages of development of individual peoples or groups of peoples. But communism is the stage of historical development which makes all existing religions superfluous and brings about their disappearance."
"What will be the attitude of communism to existing nationalities? The nationalities of the peoples associating themselves in accordance with the principle of community will be compelled to mingle with each other as a result of this association and thereby to dissolve themselves, just as the various estate and class distinctions must disappear through the abolition of their basis, private property."
"Community of women is a condition which belongs entirely to bourgeois society and which today finds its complete expression in prostitution. But prostitution is based on private property and falls with it. Thus, communist society, instead of introducing community of women, in fact abolishes it."
"What will be the influence of communist society on the family? It will transform the relations between the sexes into a purely private matter which concerns only the persons involved and into which society has no occasion to intervene. It can do this since it does away with private property and educates children on a communal basis, and in this way removes the two bases of traditional marriage – the dependence rooted in private property, of the women on the man, and of the children on the parents."
"The general co-operation of all members of society for the purpose of planned exploitation of the forces of production, the expansion of production to the point where it will satisfy the needs of all, the abolition of a situation in which the needs of some are satisfied at the expense of the needs of others, the complete liquidation of classes and their conflicts, the rounded development of the capacities of all members of society through the elimination of the present division of labor, through industrial education, through engaging in varying activities, through the participation by all in the enjoyments produced by all, through the combination of city and country – these are the main consequences of the abolition of private property."
"Education will enable young people quickly to familiarize themselves with the whole system of production and to pass from one branch of production to another in response to the needs of society or their own inclinations. It will, therefore, free them from the one-sided character which the present-day division of labor impresses upon every individual. Communist society will, in this way, make it possible for its members to put their comprehensively developed faculties to full use. But, when this happens, classes will necessarily disappear. It follows that society organized on a communist basis is incompatible with the existence of classes on the one hand, and that the very building of such a society provides the means of abolishing class differences on the other."
"Industry controlled by society as a whole, and operated according to a plan, presupposes well-rounded human beings, their faculties developed in balanced fashion, able to see the system of production in its entirety."
"Big industry, freed from the pressure of private property, will undergo such an expansion that what we now see will seem as petty in comparison as manufacture seems when put beside the big industry of our own day. This development of industry will make available to society a sufficient mass of products to satisfy the needs of everyone. The same will be true of agriculture, which also suffers from the pressure of private property and is held back by the division of privately owned land into small parcels. Here, existing improvements and scientific procedures will be put into practice, with a resulting leap forward which will assure to society all the products it needs. In this way, such an abundance of goods will be able to satisfy the needs of all its members."
"What will be the consequences of the ultimate disappearance of private property? Society will take all forces of production and means of commerce, as well as the exchange and distribution of products, out of the hands of private capitalists and will manage them in accordance with a plan based on the availability of resources and the needs of the whole society. In this way, most important of all, the evil consequences which are now associated with the conduct of big industry will be abolished. There will be no more crises; the expanded production, which for the present order of society is and hence a prevailing cause of misery, will then be insufficient and in need of being expanded much further. Instead of generating misery, overproduction will reach beyond the elementary requirements of society to assure the satisfaction of the needs of all; it will create new needs and, at the same time, the means of satisfying them. It will become the condition of, and the stimulus to, new progress, which will no longer throw the whole social order into confusion, as progress has always done in the past."
"It is a universal revolution and will, accordingly, have a universal range."
"By creating the world market, big industry has already brought all the peoples of the Earth, and especially the civilized peoples, into such close relation with one another that none is independent of what happens to the others. Further, it has co-ordinated the social development of the civilized countries to such an extent that, in all of them, bourgeoisie and proletariat have become the decisive classes, and the struggle between them the great struggle of the day. It follows that the communist revolution will not merely be a national phenomenon but must take place simultaneously in all civilized countries."
"When all capital, all production, all exchange have been brought together in the hands of the nation, private property will disappear of its own accord, money will become superfluous, and production will so expand and man so change that society will be able to slough off whatever of its old economic habits may remain."
"Once the first radical attack on private property has been launched, the proletariat will find itself forced to go ever further, to concentrate increasingly in the hands of the state all capital, all agriculture, all transport, all trade. All the foregoing measures are directed to this end; and they will become practicable and feasible, capable of producing their centralizing effects to precisely the degree that the proletariat, through its labor, multiplies the country's productive forces."
"Democracy would be wholly valueless to the proletariat if it were not immediately used as a means for putting through measures directed against private property and ensuring the livelihood of the proletariat."
"In all probability, the proletarian revolution will transform existing society gradually and will be able to abolish private property only when the means of production are available in sufficient quantity. What will be the course of this revolution? Above all, it will establish a democratic constitution, and through this, the direct or indirect dominance of the proletariat."
"The abolition of private property has become not only possible but absolutely necessary. ... The outcome can only be the victory of the proletariat."
"So long as it is not possible to produce so much that there is enough for all, with more left over for expanding the and extending the forces of production – so long as this is not possible, there must always be a ruling class directing the use of society's productive forces, and a poor, oppressed class. How these classes are constituted depends on the stage of development."
"Every change in the social order, every revolution in property relations, is the necessary consequence of the creation of new forces of production which no longer fit into the old property relations. Private property has not always existed. When, towards the end of the Middle Ages, there arose a new mode of production which could not be carried on under the then existing feudal and guild forms of property, this manufacture, which had outgrown the old property relations, created a new property form, private property. And for manufacture and the earliest stage of development of big industry, private property was the only possible property form; the social order based on it was the only possible social order."
"The abolition of private property is, doubtless, the shortest and most significant way to characterize the revolution in the whole social order which has been made necessary by the development of industry – and for this reason it is rightly advanced by communists as their main demand."
"Since the by individuals necessarily implies private property, and since competition is in reality merely the manner and form in which the control of industry by private property owners expresses itself, it follows that private property cannot be separated from competition and the individual management of industry. Private property must, therefore, be abolished and in its place must come the common utilization of all instruments of production and the distribution of all products according to common agreement – in a word, what is called the of goods."
"Abolish competition and replace it with association."
"Big industry, and the limitless expansion of production which it makes possible, bring within the range of feasibility a social order in which so much is produced that every member of society will be in a position to exercise and develop all his powers and faculties in complete freedom. It thus appears that the very qualities of big industry which, in our present-day society, produce misery and crises are those which, in a different form of society, will abolish this misery and these catastrophic depressions. We see with the greatest clarity: (i) That all these evils are from now on to be ascribed solely to a social order which no longer corresponds to the requirements of the real situation; and (ii) That it is possible, through a new social order, to do away with these evils altogether."
"It makes unavoidably necessary an entirely new organization of society in which production is no longer directed by mutually competing individual industrialists but rather by the whole society operating according to a definite plan and taking account of the needs of all."
"Big industry, competition and generally the individualistic organization of production have become a fetter which it must and will shatter."
"Everywhere the proletariat develops in step with the bourgeoisie. In proportion, as the bourgeoisie grows in wealth, the proletariat grows in numbers. For, since the proletarians can be employed only by capital, and since capital extends only through employing labor, it follows that the growth of the proletariat proceeds at precisely the same pace as the growth of capital. Simultaneously, this process draws members of the bourgeoisie and proletarians together into the great cities where industry can be carried on most profitably, and by thus throwing great masses in one spot it gives to the proletarians a consciousness of their own strength. Moreover, the further this process advances, the more new labor-saving machines are invented, the greater is the pressure exercised by big industry on wages, which, as we have seen, sink to their minimum and therewith render the condition of the proletariat increasingly unbearable. The growing dissatisfaction of the proletariat thus joins with its rising power to prepare a proletarian social revolution."
"Having destroyed the social power of the nobility and the guildmasters, the bourgeois also destroyed their political power. Having raised itself to the actual position of first class in society, it proclaims itself to be also the dominant political class. This it does through the introduction of the representative system which rests on bourgeois and the recognition of free competition, and in European countries takes the form of . In these constitutional monarchies, only those who possess a certain capital are voters – that is to say, only members of the bourgeoisie. These bourgeois voters choose the , and these bourgeois deputies, by using their right to refuse to vote taxes, choose a bourgeois government."
"The introduction of free competition is thus public declaration that from now on the members of society are unequal only to the extent that their capitals are unequal, that capital is the decisive power, and that therefore the capitalists, the bourgeoisie, have become the first class in society. Free competition is necessary for the establishment of big industry, because it is the only condition of society in which big industry can make its way."
"Wherever big industries displaced manufacture, the bourgeoisie developed in wealth and power to the utmost and made itself the first class of the country. The result was that wherever this happened, the bourgeoisie took political power into its own hands and displaced the hitherto ruling classes, the aristocracy, the , and their representative, the . The bourgeoisie annihilated the power of the aristocracy, the nobility, by abolishing the entailment of estates – in other words, by making landed property subject to purchase and sale, and by doing away with the special privileges of the nobility. It destroyed the power of the guildmasters by abolishing guilds and handicraft privileges. In their place, it put competition – that is, a state of society in which everyone has the right to enter into any branch of industry, the only obstacle being a lack of the necessary capital."
"Big industry has brought all the people of the Earth into contact with each other, has merged all local markets into one world market, has spread civilization and progress everywhere and has thus ensured that whatever happens in civilized countries will have repercussions in all other countries. It follows that if the workers in England or France now liberate themselves, this must set off revolution in all other countries – revolutions which, sooner or later, must accomplish the liberation of their respective working class."
"The manufacturing worker almost always lives in the countryside and in a more or less patriarchal relation to his landlord or employer; the proletarian lives, for the most part, in the city and his relation to his employer is purely a cash relation. The manufacturing worker is torn out of his patriarchal relation by big industry, loses whatever property he still has, and in this way becomes a proletarian."
"The proletarian works with the instruments of production of another, for the account of this other, in exchange for a part of the product. ... The proletarian liberates himself by abolishing competition, private property, and all class differences."
