This thoroughly revised and updated edition of Adrian Bardon's is a short introduction to the history, philosophy, and science of the study of time—from the pre-Socratic philosophers through Einstein and beyond. Bardon covers subjects such as time and change, the experience of time, physical and metaphysical approaches to the nature of time, the direction of time, time travel, time and freedom of the will, and scientific and philosophical approaches to cosmology and the beginning of time. He employs helpful illustrations and keeps technical language to a minimum in bringing the resources of over 2500 years of philosophy and science to bear on some of humanity's most fundamental and enduring questions.
