The Principle of Excellence is a startlingly fresh synthesis of intercultural perspective and thought. Wariboko here sets theologian Paul Tillich’s writings in creative conversation with breath-taking array of 21st-century thinkers, resulting in sparkling new insights on Tillich, but also in a daring new vision of what the field of ethics might become. A most welcome contribution to ethics and theology today.

Nimi Wariboko's deployment of the idea of excellence for social ethical thinking is both original and refreshing. Excellence is typically identified with virtue ethics, but Wariboko brilliantly demonstrates the richness and wider utility of the idea and its plural semiotic provenances. No doubt, some may find his approach daring and provocative, even stepping on the toes of some major figures in the field, but that is precisely because this is a work that is hard to ignore.

Nimi Wariboko opens new theoretical doors on the topic of virtue and excellence, unlocked by his command of classical intellectual traditions interwoven with perspectives born out of his discerning interpretations of his cross-cultural experiences.
