It has become extremely questionable whether, in the flux of life, it is a genuinely worthwhile intellectual problem to seek to discover fixed and im… - Karl Mannheim

At this point in history when all things which concern man and the structure and elements of history itself are suddenly revealed to us in a new light, it behooves us in our scientific thinking to become masters of the situation, for it is not inconceivable that sooner than we suspect, as has often been the case before in history, this vision may disappear, the opportunity may be lost, and the world will once again present a static, uniform, and inflexible countenance.

The particular conception of ideology operates primarily with a psychology of interests, while the total conception uses a more formal functional analysis, without any reference to motivations, confining itself to an objective description of the structural differences in minds operating in different social settings. The former assumes that this or that interest is the cause of a given lie or deception. The latter presupposes simply that there is a correspondence between a given social situation and a given perspective, point of view, or apperception mass. In this case, while an analysis of constellations of interests may often be necessary it is not to establish causal connections but to characterize the total situation. Thus interest psychology tends to be displaced by an analysis of the correspondence between the situation to be known and the forms of knowledge.

Relativism is a product of the modern historical-sociological procedure which is based on the recognition that all historical thinking is bound up with the concrete position in life of the thinker [Standortsgebundenheit des Denkers]. But relativism combines this historical-sociological insight with an older theory of knowledge which was as yet unaware of the interplay between conditions of existence and modes of thought, and which modelled its knowledge after static prototypes such as might be exemplified by the proposition 2 x 2 = 4. This older type of thought, which regarded such examples as the model of all thought, was necessarily led to the rejection of all those forms of knowledge which were dependent upon the subjective standpoint and the social situation of the knower, and which were, hence, merely "relative".
