Abstract
How does something come to be considered ?marginal? or ?central?? More specifically, on what grounds do particular approaches to understanding in the human and natural sciences become marginal or central? The answer to this question depends, in particular, on two different orders of analysis: a metaphysics of inquiry and an empirics of inquiry. Taken together these analyses enable us to understand why marginalities are inevitable concomitants of disciplined inquiry and how, despite their inevitability, the particular form that marginalities take in a given domain of disciplined inquiry always, and again inevitably, reflects empirical contingencies
