In so many ways, these are the guiding principles of the field of Women’s and Gender Studies (WGS) and a number of other academic disciplines concerned with exploring social identities and social justice. It is these provocations-and the accompanying desire to make the world a fairer place for everyone-that mobilize the range of thinking, approaches, concepts, and practices in this field. Many of us locate ourselves here precisely because it is a place from which we can explore the differences between people and actively resist the all-too-common tendency to transform differences into exclusions. In WGS, we find a place to join with others in asking questions about identity categories such as gender, race, sexuality, class, ability, religious affiliation, and national identity: How are these categories variously defined? What do they mean in different contexts? What roles do they play in shaping our life choices and possibilities? How does what we know about the world change when perceived through different perspectives? What shall we do with the different knowledges we gain through this work? WGS is a place not only to ask questions but to work with others in attempting to rectify some of the unfairness we find as a result.
