In 'The Spirit of Religion,' Taha Abdurrahman meticulously unpacks the limitations inherent in secular thought, arguing for a transformative shift towards an 'ethic of trustworthiness' (al-i'timaniyya). This profound philosophical work critiques the Western epistemological framework, which, according to Abdurrahman, narrows human potential and understanding of the divine. He proposes an alternative, more expansive paradigm rooted in ethical commitment, spiritual insight, and a broader engagement with reality beyond materialistic reductionism. The book challenges prevailing intellectual currents, offering a compelling vision for a revitalized religious consciousness and a more holistic approach to human existence and knowledge.
