why does the cosmos exist? could we be parts of an infinite or divine mind, as pantheists believe? if so, might we have afterlives? in immortality defended, john leslie, renowned philosopher of religion and cosmology, defends pantheism and three distinct ways in which we could be immortal.combining a creation story told by plato with the ideas of spinoza, this book tackles the fundamental questions posed by our very existence. it explores einsteinian immortality inside an eternally existing four-dimensional whole; the nature of an infinite mind which lives the lives of everybody; and the possibility of an afterlife inside such a mind. its arguments are drawn from contemporary science, and from philosophy from ancient greece onwards.this highly original work is accessible to anyone interested in science, philosophy, cosmology or theology, or to those who are just intrigued by the wonder of our being.
