Ideology and Utopia (1929)
Context: 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.
