The credit-based foundation of the science of maqasid for Taha Abdulrahman

After the book "The Ethical Concepts between Credal and Secular" in which the Moroccan philosopher known as Taha Abdul Rahman laid the foundations of his theory in credal ethics, here he is - in this book in your hands - applying this theory in the field of "the science of purposes." He sees that this science is built on the principle of claiming expertise in determining the purposes of the Lawgiver; so when the purpose-oriented says: "This is what the Lawgiver intends from His judgment," he does not only claim knowledge of the Lawgiver's judgment but also claims to judge His judgment, which makes the purpose-oriented not only a scholar but also a ruler; and if his knowledge of the Islamic ruling makes his science attain "legitimacy," then his judgment on the Islamic ruling necessitates that his knowledge attain "legality," in addition to "legitimacy." This reformer thinker has undertaken to clarify the credal foundations that provide "the science of purposes" with the required "legality," explaining how this foundational support, as much as it opens unprecedented moral horizons in this science, also requires re-examining some concepts, perceptions, and assumptions that still hinder the launch of this science into a broader horizon, so that it becomes a global moral science.
