Written by a contemporary pioneer in the area of the universal paradigm and Islamic world-systems, this book offers a fresh post-modernist outlook on new epistemological investigations in the universal paradigm. It addresses the problems of the unity of knowledge in learning systems, thereby invoking the foundations of Islamic epistemology. The author presents a phenomenological model of unity of knowledge in economics, ethics, science and society. Some critical areas where this model can be applied are also explored. As a foundational study on Islamic theory of knowledge covering the fields of Islamic economics, finance, science and society, the book will be valuable to researchers, practitioners and global academic institutions.
