Book excerpt: The book is a program which seeks to construct an intellectual framework for Islamic methodology with a view to realizing practical training in the thoughtful investigation of issues related to knowledge in various fields. The book’s title affirms the distinctive types of integration that characterize Islamic methodology, including integration of sources, means, and schools of thought, as well as existing realities with desired ideals etc. This is fully consistent with human nature, as variety is fundamental to the functions people perform and skills they master. The work essentially makes the case that fundamental to any Muslim recovery is laying the foundations of sound thinking and values that integrate the two main sources of knowledge: Revelation and Reality (that is the created worlds both physical, societal and psychological) under the umbrella of Tawhid. This concept of integration implies using both human theoretical conceptualization and practical experimental investigation whilst also affirming the need to apply human capabilities in understanding the divine text and acquiring sound knowledge of the physical world in terms of its resources, as well as accumulated past and present human experiences. The aim being to vitalize human potential and creativity.
