Henri Bergson's philosophy has attracted increasing feminist attention in recent years as a fruitful locus for re-theorizing temporality. Drawing on Luce Irigaray's well-known critical description of metaphysics as phallocentrism, Hill argues that Bergson's deduction of duration is predicated upon the disavowal of a sexed hierarchy. She concludes the article by proposing a way to move beyond Bergson's phallocentrism to articulate duration as a sensible and transcendental difference that articulates a nonhierarchical qualitative relation between the sexes.
