This entry considers the global justice movement of #MeToo: the social media-based, hashtag-driven resistance and solidarity movement against sexual harassment and violence. The entry brings into focus key aspects of the #MeToo movement, from a moral- and political-philosophical perspective. The section on “Empirical matters” sketches key events from 2017 onward. The section on “Conceptual Matters” turns to two core concepts: sexual harassment and consent, providing some historical backdrop by highlighting feminist forerunners of the #MeToo/“Me too” movement. The section on “Normative Matters” assesses the normative status of sexual harassment: why it is wrong, and in which ways unjust. It also briefly addresses the role of intersecting social identities. The section “Analytical Matters: Two Models” offers two analytical models of the dynamics of recurring anti-harassment campaigns and persisting sexual harassment. The final section “Aftermath: What Is To Be Done?” considers upshots concerning what ought to be done.
