From time immemorial, concern with timing of life has been crucial for the regulation of human praxis as well as for the philosophical quest to understand existence by seeking its meaning. The two used to inform each other, until modernity, when they parted. In spite of the extensive progress in manipulating change and motion, and of the abundance of metaphysical attempts to enlighten human beings about their fate, the puzzling nature of temporality and timing of reality remains controversial. The present collection of studies seeks a new answer by initiating a novel investigation informed by the ancient wisdom of the Greaco-Arabic-Islamic sources and inheritance, on the one side, and the contemporary discernment of Occidental phenomenology of life, on the other, in a common dialogical effort to unravel this great enigma of existence.
