Argued for radical Christian nonviolence and the refusal to answer evil with coercion. His ethical critique of violence influenced later nonviolent movements, including Gandhi’s.
Peaceful World draws on many traditions rather than a single doctrine. This page maps some of the thinkers, practices and research traditions that help shape our questions and methods.
Inclusion does not imply agreement with everything a person or tradition has said or done. Philosophical, historical, pedagogical, empirical, theoretical and practical lines sit side by side here, and genuine disagreements remain.
We use ideas as tools for inquiry and testing, not as proof that Peaceful World is “right.”
Historical context, limits of evidence, and the difference between ethical positions and empirical claims should remain visible.
These groups are practical reading paths, not an academic taxonomy. Each card names one contribution or question that is relevant to Peaceful World’s work.
