The paper identifies five presumptions of dispute theorizing: universality, ideological functionalism, settlement by courts, qualitative identity of the parties, and comparability. It is argued that these presumptions derive from or are related to the methodology of dispute theorizing, which is idealist either in the form of abstracted empiricism or logical deduction. Reasons for the sudden upsurge in dispute theorizing are discussed. Concluding, the authors evaluate attempts by dispute theorists to break away from the presumptions identified, and indicate some empirically limited but theoretically useful possibilities for futher work.
