In this pathbreaking study, Jasser Auda presents a systems approach to the philosophy and juridical theory of Islamic law based on its purposes, intents, and higher objectives (maqasid). For Islamic rulings to fulfil their original purposes of justice, freedom, rights, common good, and tolerance in today's context, Auda presents maqasid as the heart and the very philosophy of Islamic law. He also introduces a novel method for analysis and critique, utilising features from systems theory, such as, wholeness, multidimensionality, openness, and especially, purposefulness of systems. This book will benefit all those interested in the relationship between Islam and philosophy of law, morality, human rights, interfaith commonality, civil society, integration, development, feminism, modernism, postmodernism, systems theory, and culture.
