Systematic ideology is a study of ideologies founded in the late 1930s in and around London, England by Harold Walsby, George Walford and others. It seeks to understand the origin and development of ideologies, how ideologies and ideological groups work together, and the possibilities of guiding the development of ideologies on a global scale. The basic premise of systematic ideology is that ideology is the central motivator in human affairs; that the characteristics that make up the major ideologies come in sets; that those sets of characteristics form a series; and that the ideological series forms a system.
The group that formed around Harold Walsby and his ideas was a breakaway from the Socialist Party of Great Britain. During the Second World War this group developed a fascination with perceived impediments to mass socialist consciousness among the working class. The theory they developed was expressed by Walsby himself in his 1947 book The Domain of Ideologies and those involved in the group set up an organisation to propagate their views called the Social Science Association, which existed from 1944 until 1956, attracting a number of new recruits during the ‘Turner Controversy’. It was later succeeded by the Walsby Society and the journal which emerged from it called Ideological Commentary.
From the 1980s onwards, George Walford, editor of Ideological Commentary and former secretary of the SSA, watered down some of the theory’s more obviously elitist elements and even left the SPGB money at the time of his death. He did this on the grounds that although in his view the Party would never help achieve socialism it did perform a valuable function by demonstrating through its application of critical analysis, logical thought and theory the limitations of other political groups that valued these less highly (a perspective which had informed Harold Walsby’s decision in 1950 to surreptitiously rejoin the Party through its postal branch and write articles for the Socialist Standard under the pseudonym "H.W.S.Bee").
