Book excerpt: Offering a wide variety of philosophical approaches to the neglected philosophical problem of ignorance, this groundbreaking collection builds on Charles Mills's claim that racism involves an inverted epistemology, an epistemology of ignorance. Contributors explore how different forms of ignorance linked to race are produced and sustained and what role they play in promoting racism and white privilege. They argue that the ignorance that underpins racism is not a simple gap in knowledge, the accidental result of an epistemological oversight. In the case of racial oppression, ignorance often is actively produced for purposes of domination and exploitation. But as these essays demonstrate, ignorance is not simply a tool of oppression wielded by the powerful. It can also be a strategy for survival, an important tool for people of color to wield against white privilege and white supremacy. The book concludes that understanding ignorance and the politics of such ignorance should be a key element of epistemological and social/political analyses, for it has the potential to reveal the role of power in the construction of what is known and provide a lens for the political values at work in knowledge practices.
