Summary In this article the authors seek to broaden the scope of the methodological debates now underway in Germany between proponents of a critical theory of society â principally the late T. W. Adorno and J. Habermas â on the one side and proponents of an analytical theory of social science â principally Karl Popper and Hans Albert â on the other. An attempt is made to formulate and systematize some of the fundamental epistemological and methodological principles which are basic (...) to Habermas' philosophy of social science and to bring them into a critical confrontation with some of the relevant counter-positions which have today a wide currency in analytic circles.
