The unseen universe : $b or, physical speculations on a future state

by Balfour Stewart

"The Unseen Universe: or, Physical Speculations on a Future State" by B. Stewart and P. G. Tait is a scientific publication written in the late 19th century. The book delves into the intersection of science, philosophy, and religion, exploring the concept of existence beyond the visible universe and rational justifications for beliefs in an afterlife. It seeks to reconcile prevalent scientific theories with religious beliefs regarding immortality, offering an in-depth examination of various cultural perspectives on the unseen aspects of existence. At the start of the book, the authors address the increasing skepticism towards the idea of a future existence and aim to counter this with a firm argument for the compatibility of science and belief in an afterlife. They categorize thinkers into those who focus on the mechanics of the universe (the "How") and those concerned with purpose and meaning (the "Why"). The introduction sets the stage for an extensive discussion on historical beliefs regarding the afterlife from various cultures, including ancient Egyptian, Hebrew, Greek, and Eastern philosophies, culminating in a critique of materialism and a plea for a deeper understanding of the spiritual dimensions of existence that science can neither confirm nor deny.
