Comprised of a collection of articles presented by the author as a series of lectures at the Oxford Centre for Islamic Studies. This study undertakes an Islamic epistemological investigation of the social and natural sciences. The author's objective is to fathom the foundations of Islamic thought structure in a universal context: to discover a set of axioms, assumptions and worldview that would apply to both the social and scientific orders at once. The author identifies socio-scientific order as a unified perception of reality where the unicity of God can be fundamentally ingrained and analytically applied to all human systems studied. Contents: Introduction; The Concept of Human Resource Development in Islam: An Example of Application of the Unicity Precept; The Unicity Precept in the Socio-Scientific Order: Special Reference to Islamic Political Economy; Theories of Social Contract and the Principle of Ethical Endogeneity; A Substantive Study of the Principle of Ethical Endogeneity; Toward a General Theory of Islamic Social Contract.
