Our practices of knowledge attribution, acquisition, and justification can systematically disadvantage women and other subordinated groups: by excluding them from inquiry; denying them epistemic authority, denigrating their modes of knowledge; producing theories that portray them as inferior, deviant; producing social theories that make gendered power relations invisible; reinforcing gender bias and social hierarchies. Can we remedy these forms of injustice? This issue of the Rivista di estetica addresses what needs to change in our knowledge practices; how we can challenge the narrowness of what is understood as philosophical knowledge; how the concept of knowledge should be considered in connection with notions such as trust, reliance, testimony, authority, credibility; how to revisit the ways in which we measure quality and ability and what we should do in order to promote diversity and pluralism in knowledge.
