The distinguishing trait of twentieth-century intellectual life is emergence and proliferation of the “meta-disciplines” (or “metasciences”): e.g., meta-mathematics, meta-logic, meta-ethics, meta-jurisprudence, meta-politics, meta-theater, meta-language (hermeneutics and linguistic analysis), meta-sociology (sociology of knowledge), etc. The emergence of these meta-disciplines signifies a fundamental change in human orientation. We may compare this contemporary movement with the development in the eighteenth and nineteenth centuries of the special sciences as self-contained disciplines: chemistry, biology, botany, geology, history, psychology, etc. Whereas this earlier period proliferated special sciences through the application of rigorous techniques which critically reduced (and therefore multiplied) the objects of science per se, the characteristic of contemporary intellectual life is the proliferation of meta-disciplines through the critical analysis of the methods and the presuppositions of the special sciences themselves. I believe this peculiar intellectual activity, which underlies the emergence of all contemporary meta-disciplines, is the major clue to understanding the fundamental reorientation of personal and social consciousness which is going on today. Moreover, this change is rich with possibilities for new ways of dealing with the technological and institutional impasse which is the fruit of the development of the special sciences.
