"We refer to time constantly and we measure its passing--but do we know what it actually is? In What Is Time?, Truls Wyller enquires into time's complex nature, juxtaposing the latest scientific theories with our personal experience of chronology. After examining the notion of time in physics, history, religion, anthropology, philosophy and literature, Truls 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, the book gives an accessible, rounded portrait of the nature of time, and is essential reading for those who wish to gain a deeper understanding of the motion of our everyday existence."--back cover.
