Abstract
Heidegger's phenomenological approach, as exhibited in Being and Time, provides a conceptual background to discussions in role?theory. His work was not meant as an empirical contribution to sociology, nor does he assimilate sociology to conceptual inquiry. Heidegger's contention is, rather, that if we understand the way in which human beings exist (the nature of Dasein) we shall understand why empirical role?theoretical inquiries are possible. Without experience, without paying attention to the facts of human life, there could be no phenomenological enterprise. But by eliciting the fundamental structure of Dasein Heidegger has pointed to what makes the empirical data ultimately intelligible. The enterprise is a transcendental one, in the Kantian sense
