Abstract
This Editorial to the 20th Anniversary Issue of Ethical Theory and Moral Practice outlines key challenges and opportunities arising from the recent explosion of responsibility studies in different areas. The underlying ambition is to counter the trend of fragmenting the philosophical debate around responsibility by bringing together helpful insights on related dimensions. The discussion is organised around three main themes: (1) Accountability, Attributability, Answerability, Liability; (2) Individuals, Collectives, Practices, and Institutions; and (3) Harms and Wrongs.
