"The particular conception of "ideology" makes its analysis of ideas on a purely psychological level. If it is claimed for instance that an adversary is lying, or that he is concealing or distorting a given factual situation, it is still nevertheless assumed that both parties share common criteria of validity — it is still assumed that it is possible to refute lies and eradicate sources or error by referring to accepted criteria of objective validity common to both parties. The suspicion that one's opponent is the victim of an ideology does not go so far as to exclude him from discussion on the basis of a common theoretical frame of reference. The case is different with the total conception of ideology. When we attribute to one historical epoch one intellectual world and to ourselves another one, or if a certain historically determined social stratum thinks in categories other than our own, we refer not to the isolated cases of thought-content, but to fundamentally divergent thought-systems and to widely differing modes of experience and interpretation."

“Every bureaucracy, therefore, in accord with the peculiar emphasis on its own position, tends to generalize its own experience and to overlook the fact that the realm of administration and of smoothly functioning order represents only a part of the total political reality. Bureaucratic thought does not deny the possibility of the science of politics, but regards it as identical with the science of administration. Thus irrational factors are overlooked, and when these nevertheless force themselves to the fore, they are treated as "routine matters of state.”

“It may possibly be true that, to continue to live on and to act in a world like ours, it is vitally necessary to seek a way out of this uncertainty of multiple alternatives; and accordingly people may be led to embrace some immediate goal as if it were absolute, by which they hope to make their problems appear concrete and real. But it is not primarily the man of action who seeks the absolute and immutable, but rather it is he who wishes to induce others to hold on to the status quo because he feels comfortable and smug under conditions as they are.”

“We are faced with the curiously appalling trend of modern thought, in which the absolute which was once a means of entering into communion with the divine, has now become an instrument used by those who profit from it, to distort, pervert, and conceal the meaning of the present.”

“It has become extremely questionable whether, in the flux of life, it is a genuinely worthwhile intellectual problem to seek to discover fixed and immutable ideas or absolutes. It is a more worthy intellectual task perhaps to learn to think dynamically and relationally rather than statically.”

“In attempting to expose the views of another, one is forced to make one's own view appear infallible and absolute, which is a procedure altogether to be avoided if one is making a specifically non-evaluative investigation. The second possible approach is nevertheless to combine such a non-evaluative analysis with a definite epistemology. Viewed from the angle of this second approach there are two separate and distinct solutions to the problem of what constitutes reliable knowledge — the one solution may be termed relationism, and the other relativism.”

“In order to be transmuted into knowledge, every perception is and must be ordered and organized into categories. The extent, however, to which we can organize and express our experience in such conceptual forms is, in turn, dependent upon the frames of reference which happen to be available at a given historical moment. The concepts which we have and the universe of discourse in which we move, together with the directions in which they tend to elaborate themselves, are dependent largely upon the historical-social situation of the intellectually active and responsible members of the group.”
