This book is intended as an invitation to the philosophy of space, time, and motion — a field that has formed a central core of natural philosophy for some twenty-five centuries. It is designed as a sort of sampler, being neither a systematic survey of problems and points of view, nor (although the topics come from many different periods) a comprehensive historical account. It treats, instead, an assortment of issues, at an extremely elementary level, that concern people working in this area. I hope that discussions of such topics as the nature and implications of non-Euclidean geometry, ancient and modern versions of Zeno’s paradoxes, and the features of time as revealed by special relativity (including the famous “twin paradox”) will prove fascinating enough to motivate the reader to pursue these ideas in more systematic and advanced texts.
