New Proofs for the Existence of God offers a beautifully lucid system of reasoning demonstrating not only the existence, but also the necessity of God.
Throughout the first chapters of the book, Spitzer shows how contemporary science strengthens the idea of a continuous and wilful act of creation. Frequently the new atheists co-opt science for their own ends, asserting that science and belief in God are irreconcilable. However, the view Spitzer takes here is that the two are harmonious, given a proper understanding of what science is actually showing us and how this in turn relates to a classical understanding of what God is: not simply a being among many, but the sheer act of to be itself. Or ipsum esse subsistens, as Aquinas states.
The second part presents three philosophical arguments for the existence of God. Whilst the philosophical reasoning is at times heavy, it is nonetheless rewarding upon completion. Even if the reader is not totally convinced, this section will at least extirpate the charge that belief in God is irrational, with no basis in reason or reality. For those who are open-minded, it may initiate a process of deeper contemplation, leading to the conclusion that there may in fact be a Being whose raison d'Ítre is simply 'to be', who is the continuous creator of all else that is.
The last part of the book concerns the transcendentals. By far the most interesting and enjoyable section of the book, it deals with the properties of the being as proven in part two, viz. that it is truth itself, love itself, justice/goodness itself, beauty itself, and being itself; and how we as humans relate to such mysteries.
Overall it is a challenging read which engages the mind. It at least deserves consideration as a great work of contemporary reasoning, which demonstrates the validity of a belief in God.
