The author presents a critical evaluation of empiricist and positivist theories of knowledge, and investigates some classic attempts at using them to provide the philosophical foundation for a scientific sociology. He takes the Kantian critique of empiricism as the starting point for the main anti-positivist and anti-naturalist philosophical approaches to the social studies. He goes on to investigate the inadequacy of post-Kantian arguments from Rickert, Weber, Winch and others, both against non-positivist forms of naturalism and as the possible source of a distinctive philosophical foundation for the social studies.
The book concludes with a critical investigation of the Marxian tradition and an attempt to establish the possibility of a materialist and realist defence of the project of a natural science of history, which escapes the fundamental flaws of both positivist and neo-Kantian attempts at philosophical foundation.
