To say that Mr. Lichtheim has restated an argument is not to detract from the value of the essay, which, following that of Hans Barth's Wahrheit und Ideologic, is one of the best accounts of the evolution of the concept.

Since completing this exchange I have read Hans Neisser's On the Sociology of Knowledge (New York, 1965) and would recommend it as an important statement on the means of creating an "ideology-free" social science. By setting down "rules of procedure for the non-experimental sciences," Professor Neisser indicates the direction whereby a social science can be free of relativism and objective in its statements about behavior.
