In this article, I lend support to Miranda Fricker's work in social epistemology from a post-Kantian point of view. In Epistemic Injustice: Power and The Ethics of Knowing, Fricker writes that, at times, social power, rather than the actual possession of knowledge, determines whether a speaker is believed (Fricker, 2007, 1-2). I will develop Miranda Fricker's project in feminist epistemology by examining the post-Kantian linguistic sign with a view to showing how G.W.F. Hegel and Jacques Derrida transform the Kantian analytic/synthetic (...) contrast in their semiologies. Epistemic injustice arises not only from cultural stereotypes and impoverished categories of identity but, also, from the dynamic way that language generates meaning. (shrink)
