'He is the First and the Last, the Manifest and the Hidden.'

What is existence?Why is there something rather than nothing?Why does the universe possess intelligible order, mathematical structure, and conscious experience?This book develops a rigorous philosophical framework addressing these questions through a unified ontology of existence inspired by the Qur’anic statement:'He is the First and the Last,the Manifest and the Hidden.'Qur’an 57:3Rather than treating this verse as only a theological expression, the work interprets it as a profound ontological structure describing reality itself.The book integrates:philosophy of existence,philosophy of science,consciousness studies,metaphysics,and structural ontologyinto a single coherent framework.At the center of the work is the argument that observable reality is not self-sufficient. Every manifest structure exists within networks of dependency, while scientific laws describe stable relations rather than creating them. Time is reinterpreted as an ordered structure of dependent change, not an independently flowing substance. Consciousness is examined not as a secondary accident of matter, but as a necessary condition for observation and experiential disclosure.The framework develops a fourfold ontology:The First - the non-dependent ground of existenceThe Last - continuity of existence beyond changing formsThe Manifest - the observable and measurable structure of realityThe Hidden - the deeper ontological depth beyond direct observationThese dimensions are presented not as separate metaphysical realms, but as interdependent aspects of one unified reality.The book argues that science, while extraordinarily powerful, remains a partial reading of existence because scientific knowledge depends upon observation, intelligibility, and conscious access. Observable reality therefore points beyond itself toward deeper grounding conditions that cannot be reduced to physical description alone.To support this framework, the work introduces formal ontological notation and symbolic expressions describing dependency, grounding, manifestation, continuity, and consciousness. These formulations are used not as conventional physical equations, but as structural representations of ontological relations.Positioned as a contemporary Qur’anic philosophy of existence, this work seeks to establish a non-reductionist vision of reality in which science, consciousness, and metaphysical inquiry converge into a unified philosophical system.Rather than presenting existence as a collection of isolated objects or forces, the book proposes that reality is fundamentally:grounded,continuous,intelligible,manifested,and transcendent beyond complete objectification.This work is intended for readers interested in ontology, metaphysics, philosophy of science, consciousness studies, cosmology, and the deeper philosophical foundations of reality itself.
