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 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.

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.

When the great religious and philosophical conceptions were alive, thinking people did not extol humility and brotherly love, justice and humanity because it was realistic to maintain such principles and odd and dangerous to deviate from them, or because these maxims were more in harmony with their supposedly free tastes than others. They held to such ideas because they saw in them elements of truth, because they connected them with the idea of logos, whether in the form of God or of a transcendental mind, or even of nature as an eternal principle.

Reason as an organ for perceiving the true nature of reality and determining the guiding principles of our lives has come to be regarded as obsolete.

As soon as a thought or word becomes a tool, one can dispense with actually 'thinking' it, that is, with going through the logical acts involved in verbal formulation of it. As has been pointed out, often and correctly, the advantage of mathematics - the model of all neo-positivistic thinking - lies in just this 'intellectual economy.' Complicated logical operations are carried out without actual performance of the intellectual acts upon which the mathematical and logical symbols are based. ... Reason ... becomes a fetish, a magic entity that is accepted rather than intellectually experienced.

At present, when the prevailing forms of society have become hindrances to the free expression of human powers, it is precisely the abstract branches of science, mathematics and theoretical physics, which ... offer a less distorted form of knowledge than other branches of science which are interwoven with the pattern of daily life, and the practicality of which seemingly testifies to their realistic character.
