Adel Mahmoud Badr's profound philosophical work, 'The Concept of Temporal Occurrence in the Metaphysics of Existence,' delves into a fundamental metaphysical problem: how events and entities emerge within the framework of eternity. This book critically examines the notion of 'Daehrani' occurrence, which describes phenomena arising within the ceaseless flow of everlasting time, distinguishing it from conventional temporal or eternal existence. Badr meticulously explores various metaphysical perspectives, analyzing how different philosophical traditions have grappled with the nature of origination and the intricate relationship between transient events and an immutable, timeless reality. It offers a compelling intellectual journey for anyone interested in advanced metaphysics, the philosophy of time, and the complex dynamics of existence.
