When even the dictators of today appeal to reason, they mean that they possess the most tanks. They were rational enough to build them; others should be rational enough to yield to them.

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.

Notwithstanding their attacks on the basic conception of rationalism, on synthetic a priori judgments, that is, material propositions that cannot be contradicted by any experience, the empiricist posits the forms of being as constant.

Reason has never really directed social reality, but now reason has been so thoroughly purged of any specific trend or preference that it has finally renounced even the task of passing judgment on man's actions and way of life. Reason has turned them over for ultimate sanction to the conflicting interests to which our world actually seems abandoned.

Although the formulations of science now offer the most advanced knowledge of nature, men continue to use obsolete forms of thought long discarded by scientific theory. In so far as these obsolete forms are superfluous for science, the fact that they persist violated the principle of the economy of thought, that characteristic trait of the bourgeois temper.

If the subjectivist view hold true, thinking cannot be of any help in determining the desirability of any goal in itself. The acceptability of ideals, the criteria for our actions and beliefs, the leading principles of ethics and politics, all our ultimate decisions are made to depend upon factors other than reason. They are supposed to be matters of choice and predilection, and it has become meaningless to speak of truth in making practical, moral or esthetic decisions.

The more the concept of reason becomes emasculated, the more easily it lends itself to ideological manipulation and to propagation of even the most blatant lies. ... Subjective reason conforms to anything.
