The subject of 'time' is currently experiencing a revival in the most diverse areas of academic discourse. Contemporary time theory attempts to relate theoretical time concepts both to one another and to everyday experience of time. This book deals with the philosopher Martin Heidegger and the chemo-physicist Iyla Prigogine (Nobel Prize for Chemistry 1977), two prominent advocates of pioneering time concepts in the 20th century. The author not only provides a transdisciplinary introduction to modern debate on the problem of time, but suggests how the basic tendencies in this debate might be pragmatically interlinked with each other.
