“In the Diary which begins 1845 there is a much larger infusion of secular matter. I find myself deep in the literary history of the eighteenth century, reading Gray's Correspondence, Prior's Life of Goldsmith, Hume's Life and Correspondence …”

(version in original Dutch / citaat van Bilders' brief, in het Nederlands:) ..niet minder bemin ik toch de graauwe wateren van mijn Holland, hunne ernstige, eenigsinds droeve kleur, die zoo goed overeenkomt met de even grijze luchten en dampen, dier er overeen hangen.

Beyond the Veil
Context: The reason which placed the stars, the sense of proportion which we recognize in the planetary system, finds its correspondence in this brain of ours. We question every feature of what we see, think, and feel. We try every link of the chain and find it sound if we ourselves are sound. This power of remotest question and assent is not of to-day nor yesterday.
It transcends all bounds of time and space. It weighs the sun, explores the pathway of the stars, and writes, having first carefully read, the history of earth and heaven. It moves in company with the immortals. How much of it is mortal? Only so much as a small strip of earth can cover. These remains are laid away with reverence, having served their time. But what has become of the wonderful power which made them alive? It belongs to that in nature which cannot die.

Awareness and consciousness

Preface to ' (1859).
Source: A Contribution to the Critique of Political Economy
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: A third kind of semantic awareness is an extension of the consciousness of abstracting, namely an awareness of varying levels of abstraction. Words vary in the degree to which they correspond to verifiable referents. Some words are relatively more abstract or general, and some words are relatively more concrete or specific. Related to this fact is a fourth kind of semantic awareness, which might be called the "direction of meaning." That is, with increasingly abstract or general words, (i. e., those farther removed from operationally verifiable referents), the direction of meaning shifts accordingly from "outside" to "inside." With increasingly concrete or specific words (i. e., those whose referents can be more easily verified operationally), the direction of meaning shifts accordingly from "inside" to "outside." The conventional semantic terminology for these directions of meaning are intensional (internal or inside) and extensional (external or outside). Closely bound to these directions of meaning are, of course, different kinds of meaning. The primary semantic distinction made in kinds of meaning is between connotation (intensional, subjective, personal meaning) and denotation (extensional, objective, social meaning).
