"Remarks on the concept of simultaneity may mislead the reader to believing that only modern physicists and philosophers recognize the crucial importance of this notion. ...this concept has occupied the attention of philosophers and scientists throughout the whole history of human thought and played an important role in the writings of such intellectual giants as Aristotle, St. Augustine, Leibniz, and Kant. It would be a serious mistake to associate the concept of simultaneity exclusively with philosophic or scientific reasoning. In fact it was at the level of prescientific apprehension, a fundamental ingredient in the process of human apperception and conception of time. As Gerald Whitrow rightly pointed out, "our conscious appreciation of the fact that one event follows another is of a different kind from our awareness of either event separately. If two events are to be represented as occurring in succession, then—paradoxically—they must also be thought of simultaneously.""
