Giovanni Arrighi's The Geometry of Imperialism was published by New Left Books in 1978, in a translation by Patrick Camiller. "I was disturbed, at the time," Arrighi later told David Harvey, "by the terminological confusions that were swirling around the term ‘imperialism’. My aim was to dissipate some of the confusion by creating a topological space in which the different concepts, which were often all confusingly referred to as ‘imperialism’, could be distinguished from one another."
In Marxist debate, Arrighi argued, such confusions could be traced to Lenin's classical theory of imperialism, which at times fails to clearly distinguish it from "the monopoly stage of capitalism" or "finance capital." Arrighi's study would then be neither "a simple reproduction of the thought of this or that theoretician" nor the development of a new theory of imperialism, but rather an examination of "the presuppositions of the theory of imperialism in order to explicate, specify, and delimit them." Those presuppositions were to be located not in Lenin's own theory, but in that of J.A. Hobson, which preceded it.
In the excerpt below, the book's first chapter, Arrighi identifies four primary elements of Hobson's conception of imperialism and isolates them in the form of Weberian ideal types, which them serve as the coordinates for his "topological" reconstruction.
It is no easy task to define the concept of imperialism. The same term is customarily used to designate diverse, and in certain respects antithetical, concepts. Indeed, theoretical controversy is often based on nothing more than a failure to grasp what is the object of reference.
