In the history of relations among Islam, Christianity, and Judaism, the encounter in medieval Spain was unique in its intensity and creativity, with an abundance of polemical texts resulting from this rich exchange. This study focuses on the Treatise on Obvious Contradictions and Evident Lies by Muslim scholar Abu Muhammad 'Ali ibn Hazm al-Andalusi (d. 1064), placing it in the context of the historical and socio-cultural dynamics of 11th century Islamic Spain and arguing that Ibn Hazm wrote it for the purpose of effecting societal reform.
