The author Ayatollah Javadi Amoli expands upon the differences between the sources of obligation and right and the impact of this difference upon the principles of obligation and right, offering the audience an interesting outlook. In order to describe the difference between the sources of obligation and right among Muslims and Westerners, attention has been paid to the essential point that difference between principles is often rooted in difference between sources and this difference revolutionizes the course of human’s thought. Therefore, should the sources be different, consensus and ideology in principles does rarely come about. Hence, the principles of the belief rooted in intellect, revelation, and religious texts, cannot be one and the same as the principles of the one rooted in experience and instrumental intellect. It seems as though, only tracing back the issue of right and obligation as well as all legal and jurisprudential issues back to their roots will guarantee a desirable outcome. In fact, this subject is ancillary to the issues of epistemology, divinity, anthropology, and theology. In the same way that laws, edicts, and obligations are concepts, which assume meaning in relation to human and his/her individual and social life in the face of authority. In order to lend the discussion some order and organization, the subjects explored in the book have been subsumed under the titles of the relationship between epistemology and legal issues, the relationship between ontology and the issue of right and obligation, and the relationship between anthropology and theology.
