The Fourth Dimension of Existence

We rated this book:


We live in a three-dimensional world, and can fully understand three -dimensional occurrences. But this three- dimensional reality cannot explain our inability to answer fundamental questions. The Fourth Dimension of Existence proposes that an additional existential dimension is needed — another dimension, like the three material ones with which we are so familiar, which is an integral part of our being, which we already can sense and understand in a limited capacity, but which in us is not yet fully realized. This fourth dimension is Spirit, and by accepting that we have this particular fourth-dimensional component, we can begin to rationally understand many of these questions about our existence, if not yet their answers.

Dr. Nasr Saad begins with an overview of our understanding of the universe – basically, that we cannot comprehend it in terms of our normal reality. Although matter is finite and limited, the universe, as far as we can tell, is infinite and limitless. How can this be? He explores the historical and universal understanding that there is an immortal component to our beings, usually explained as the spirit or soul, but explains that the spirit and body are both equally present throughout and within our being. The three familiar dimensions of physical reality are no more or less omnipresent than this fourth, the spirit.

Understanding that we are not fully realized in the fourth dimension, although we can vaguely sense it, we recognize that communication from that reality must be by analogy or parable. Dr. Saad compares this to us, as three-dimensional beings, trying to interact with two-dimensional ones. (This analogy borrows heavily from Flatland, by Edwin A. Abbot, but explicates to a much greater degree than was explored in that already excellent book.) Different chapters focus more exclusively on death and immortality, religious revelations, and time and space. This last is especially fun; using the experimentally-supported conclusions of Einstein’s Theory of Relativity, for example, Dr. Saad shows how a being moving at or beyond the speed of light would, to our comprehension, exist for our eternity and throughout our infinite space.

This is a fascinating book. The arguments are painstakingly, thoroughly, and solidly constructed. Although the reading can be dense and get a little confusing (as the subject is, by this book’s argument, not completely comprehensible), it is well worth the effort. The style is highly readable and conversational, and Dr. Saad is modest and respectful as he leads you to his conclusions. He does not claim to have the answers, but invites the reader to come with him in trying to understand life’s mysteries. Even if you don’t believe in an existence beyond the one we know, The Fourth Dimension of Existence provides a rational way to try to approach that belief. If you do already believe in that possibility, this book will wonderfully extend your understanding.
