It explores factors which drive the advocacy of human rights integrating religious values reflected in human rights law. The book explores human rights activism in the history of ideas and the contributions of Celtic culture. It develops the framework for understanding the human rights struggle and the advocacy functions which drive it, exploring the critical role of emotion in the form of sentiment, either positive or negative, that promotes or prevents human rights violations.

Further chapters explore affect, gender, and sexual orientation, human rights and socio-economic justice, human rights and revolution, transitional justice, indigenous human rights, nuclear weapons and intellectual property.
