Fifty Years of Ideology: A Selective Survey of Academic Economics in the United States 1930 to 1980
Ideology as a mixture of consciously or unconsciously accepted ideas and beliefs provides the underlying support or rationalisation for fundamental features of thought and action in a society. A vigorously promoted contending ideology may at any given time also influence developments. Value judgments, which are likewise not based on the logical rules of observation and verification, may for present purposes be taken as concerned with less comprehensive or less fundamental matters than ideology.
