We speak of consciousness, or awareness, or the I, or my inner being, or sentience. It may reach to the deeper metaphysical levels of the universe, but what is its relation to the material world? What is this relation from the perspective of science? Science always builds carefully, slowly, and can start to have a somewhat mathematical character. Does meaning exist outside and independent of the human mind? What is meaning's relation to time and space? Are there different I's? Is the idea of death so simple? Apart from obvious fictional parts, the book is valid science, philosophy, and logic. The author's background includes, over time, having gone into the works of many philosophers. Earlier, the author obtained masters degrees and doctoral work in mathematical logic at the University of California at Berkeley, and in artificial intelligence at Stanford University. (This 2008 book is the same as the 2005 edition except for the description above, covers, text on covers, contact website.)
