Pioneering lawyer and activist for women’s rights Catharine A. MacKinnon argues that seemingly minor interventions in the legal realm can have a butterfly effect that generates major social and cultural transformations.

Catharine MacKinnon is a pioneer of legal theory and practice, a groundbreaking activist for women’s rights, and one of feminism’s most significant figures. For over forty years MacKinnon’s intellectual, legal, and political pursuits have been defined by a driving motivation: to end inequality, including abuse, in women’s lives. Many of her ideas are now staples of legal and political discourse. Others urge changes that have yet to be realized.
