Context: No thinking man in this day can fail to recognise that one cannot properly evaluate an historical period without considering economic conditions. But much more one-sided is the view which maintains that all history is merely the result of economic conditions, under whose influence all other life phenomena have received form and imprint.
There are thousands of events in history which cannot be explained by purely economic reasons, or by them alone. It is quite possible to bring everything within the terms of a definite scheme, but the result is usually not worth the effort. There is scarcely an historical event to whose shaping economic causes have not contributed, but economic forces are not the only motive powers which have set everything else in motion. All social phenomena are the result of a series of various causes, in most cases so inwardly related that it is quite impossible clearly to separate one from the other. We are always dealing with the interplay of various causes which, as a rule, can be clearly recognised but cannot be calculated according to scientific methods.

The greatest unsolved mysteries are the mysteries of our existence as conscious beings in a small corner of a vast universe.

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.
