We refer to time constantly, and we compulsively measure its passing—but do we know what it actually is? In , Truls Wyller enquires into time’s complex nature, juxtaposing the latest scientific theories with our personal experience of chronology. The book examines the notion of time in physics, history, religion, anthropology, philosophy, and literature, and Wyller concludes by proposing his own theory of time: that the temporal character of any series of events is essentially practical and derived from human life. Written from a philosophical perspective, gives an accessible, rounded portrait of the nature of time, and it is essential reading for those who wish to gain a deeper understanding of the motion of our everyday existence.
