The Philosophy of Time and the Philosophy of Space are some of the most neglected branches of philosophy to date. Of course it is mainly the natural philosophy of Physics that mainly focuses on the implications and the concept of time and the relation to spatial ontology. This book is a great book for anyone who has the guts to engage with the possibilities, contradictions, and paradoxes of the natural phenomena of time and the relationship to space. We all talk about time, more so than space, and some of us even complain about how little time we have and the like. But do we truly know what time is and how it affects our statements, in terms of controlling tense in our language? This book helps understand the concepts of time and helps us use precise language in terms of talking about the past, present, and future along with space thrown in the mix.Robin Le Poidevin does humanity a service for writing this book and summarizing the dialogues on time and it's relation to space.On this discourse Poidevin, delves into concepts in mathematics such as the plausible tension between classical Euclidian space and non Euclidian space as first mentioned by Nikolai Lobachevski. Dimensionality is touched on a bit, in terms of what a dimension really is. Furthermore, the book should really be bought for the discussion of the A Theory of Time and B Theory of Time and McTaggart's proof of the unreality of time. Time travel also has its due portion in the book. Is time travel even possible? Poidevin does an excellent job in presenting plausible time travel scenarios and discussing the paradoxes and nonsense that arises from plausible scenarios of time travel and as always, discussion of the Arrow of Time (the direction of time) is found within this book as well. Even the location of time is mentioned! Is there differing times for different locations in space? Read this book. As always, Zeno and his classical paradoxes of movement and motion are also mentioned within the book and add insight to classical Greek views of time. Especially that of Aristotle. The edge of space is also discussed along with Pythagoras's encounters with space and its difficulties. Even the origins of time and space have their place within this book along with God's relation to time. If you are interested with God and time, then William Lane Craig, another philosopher, has an excellent discourse on this called Time and Eternity: Exploring God's Relationship to Time and a book called God & Time: 4 Views is recommended. Otherwise, stick with this book.Overall, this book is pretty dense. It is dense enough to entertain and enlighten, but not enough to bore or too technical in its language. It's a historical, mathematical, and mainly philosophical discourse on the debates on space and time form a professional philosopher's out look. If you are tired of reading and hearing horribly oversimplified talk of space and time by natural philosophers like Physicists, then try the general philosophers' take on the issue.Here is a list of all the Chapters with few sections mentioned (I am not writing all the section names, just some that I think will catch your eyes)Ch 1.
