“The melancholy science from which I make this offering to my friend relates to a region that from time immemorial was regarded as the true field of philosophy, but which, since the latter’s conversion into method, has lapsed into intellectual neglect, sententious whimsy and finally oblivion: the teaching of the good life. What the philosophers once knew as life has become the sphere of private existence and now of mere consumption, dragged along as an appendage of the process of material production, without autonomy or substance of its own.”

Preface to ' (1859).

Context: In the social production of their life, men enter into definite relations that are indispensable and independent of their will; these relations of production correspond to a definite stage of development of their material forces of production. The sum total of these relations of production constitutes the economic structure of society — the real foundation, on which rises a legal and political superstructure and to which correspond definite forms of social consciousness. The mode of production of material life determines the social, political and intellectual life process in general. It is not the consciousness of men that determines their being, but, on the contrary, their social being that determines their consciousness. [Es ist nicht das Bewußtsein der Menschen, das ihr Sein, sondern umgekehrt ihr gesellschaftliches Sein, das ihr Bewusstsein bestimmt. ] At a certain stage of their development, the material productive forces in society come in conflict with the existing relations of production, or — what is but a legal expression for the same thing — with the property relations within which they have been at work before. From forms of development of the productive forces these relations turn into fetters. Then begins an epoch of social revolution. With the change of the economic foundation the entire immense superstructure is more or less rapidly transformed. In considering such transformations a distinction should always be made between the material transformation of the economic conditions of production, which can be determined with the precision of natural science, and the legal, political, religious, aesthetic or philosophic — in short, ideological forms in which men become conscious of this conflict and fight it out. Just as our opinion of an individual is not based on what he thinks of himself, so we can not judge of such a period of transformation by its own consciousness; on the contrary, this consciousness must be explained rather from the contradictions of material life, from the existing conflict between the social productive forces and the relations of production. No social order ever disappears before all the productive forces for which there is room in it have been developed; and new, higher relations of production never appear before the material conditions of their existence have matured in the womb of the old society itself. Therefore, mankind always sets itself only such tasks as it can solve; since, looking at the matter more closely, we will always find that the task itself arises only when the material conditions necessary for its solution already exist or are at least in the process of formation. In broad outlines we can designate the Asiatic, the ancient, the feudal, and the modern bourgeois modes of production as so many progressive epochs in the economic formation of society. The bourgeois relations of production are the last antagonistic form of the social process of production — antagonistic not in the sense of individual antagonism, but of one arising from the social conditions of life of the individuals; at the same time the productive forces developing in the womb of bourgeois society create the material conditions for the solution of that antagonism. This social formation constitutes, therefore, the closing chapter of the prehistoric stage of human society.

Context: True intellectual culture and the demand for higher interests in life does not become possible until man has achieved a certain material standard of living, which makes him capable of these. Without this preliminary any higher intellectual aspirations are quite out of the question. Men who are constantly threatened by direst misery can hardly have much understanding of the higher cultural values. Only after the workers, by decades of struggle, had conquered for themselves a better standard of living could there be any talk of intellectual and cultural development among them. But it is just these aspirations of the workers which the employers view with deepest distrust. For capitalists as a class, the well-known saying of the Spanish minister, Juan Bravo Murillo, still holds good today:"We need no men who can think among the workers; what we need is beasts of toil."

The Making of an Elder Culture (2009)
Context: The final stage of life... offers us the opportunity to detach from competitive, high-consumption priorities... At that point, life itself—the opportunity it offers for growth, for intellectual adventure, for the simple joys of love and companionship, for working out our salvation—comes to be seen as our highest value.... That is what I have always assumed it means to be countercultural.
