  Feminist philosophy of biology is also driven by epistemic motivations. For example, feminists such as Ruth Bleier (1984) and Anne Fausto-Sterling (1985/1992) reveal that sexist and androcentric biases can be found in the biological knowledge produced according to biological science's contemporary best practices or accepted epistemic standards. This can drive more general questions about the role that values in general, and gender values in particular, play in the production of scientific or biological knowledge (Longino 1990, 2002; Richardson 2008).
