Philosophy is overwhelmingly complicated, its procedure depressingly slow.

Plato and his objectivistic successors ... preserved the awareness of differences that pragmatism has been invented to deny the difference between thinking in the laboratory and in philosophy, and consequently the difference between the destination of mankind and its present course.

The complexity of the connection between the world of perception and the world of physics does not preclude that such a connection can be shown to exist at any time.

Calvin's theocentric irrationalism eventually revealed itself as the cunning to technocratic reason which had to shape its human material. Misery and the poor laws did not suffice to drive men into the workshops of the early capitalistic era. The new spirit helped to supplement external pressures with a concern for wife and child to which the moral autonomy of the introverted subject in reality was tantamount.

The quality of the human that precludes identifying the individual with the class is 'metaphysical' and has no place in empiricist epistemology. The pigeon hole into which a man is shoved circumscribes his fate.

The disparagement of empirical evidence in favor of a metaphysical world of illusion has its origin in the conflicy between the emancipated individual of bourgeois society and his fate within that society.

The facts which our senses present to us are socially performed in two ways: through the historical character of the object perceived and through the historical character of the perceiving organ.
