Subjective reason … is inclined to abandon the fight with religion by setting up two different brackets, one for science and philosophy, and one for … - Max Horkheimer

The inversion of external compulsion into the compulsion of conscience … produces the machine-like assiduity and pliable allegiance required by the new rationality.

The basic ideals and concepts of rationalist metaphysics were rooted in the concept of the universally human, of mankind, and their formalization implies that they have been severed from their human content. How this dehumanization of thinking affects the very foundations of our civilization can be illustrated by analysis of the principle of the majority, which is inseparable from the principle of democracy. In the eyes of the average man, the principle of the majority is often not only a substitute for but an improvement upon objective reason: since men are after all the best judges of their own interests, the resolutions of a majority, it is thought, are certainly as valuable to a community as the intuitions of a so-called superior reason. … What does it mean to say that “a man knows his own interests best”—how does he gain this knowledge, what evidences that his knowledge is correct? In the proposition, “A man knows [his own interests] best,” there is an implicit reference to an agency that is not totally arbitrary … to some sort of reason underlying not only means but ends as well. If that agency should turn out to be again merely the majority, the whole argument would constitute a tautology. The great philosophical tradition that contributed to the founding of modern democracy was not guilty of this tautology, for it based the principles of government upon … the assumption that the same spiritual substance or moral consciousness is present in each human being. In other words, respect for the majority was based on a conviction that did not itself depend on the resolutions of the majority.

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.
