In Works Righteousness, Anna L. Peterson examines the place of practice in contemporary ethical theory. Peterson argues that rather than assuming that pre-established moral ideas guide action, ethicists should acknowledge and explore the relationship between ideas, actions, and results. Both an analysis of alternative models in which practice plays a stronger role and an argument for taking practice more seriously in broad questions of ethics as well as in concrete case studies, Works Righteousness contends that what we do generates and alters our values, just as often as expressed values motivate or guide the ways we act.

Peterson here challenges prevailing philosophical and religious theories that ideas are what truly matter, underlining the value of attention to people's concrete experiences and highlighting the relevance of theoretical insights to contemporary social issues such as climate change, euthanasia, and hate speech. Through examinations of pragmatism, Marxism, and religious pacifism, all of which significantly highlight a practice-focused approach, Works Righteousness addresses the way social structures condition moral ideas and actions, the dangers of thinking about moral problems as polarized dilemmas, and the complex mutual shaping of ideas and actions.
