This book develops a novel argument which combines the Kalam with the Thomistic Cosmological
Argument. It approaches an ongoing dispute concerning whether there is a First Cause of time
from a radically new point of view namely by demonstrating that there is such a First Cause
without requiring the controversial arguments against concrete infinities and against
traversing an actual infinite (although the book presents original defenses of these arguments
as well). This book also develops a novel philosophical argument for the Causal Principle
namely that 'everything that begins to exist has a cause' and offers a detailed discussion on
whether a First Cause of time can be avoided by a causal loop. It also addresses
epistemological issues related to the Cosmological Argument which have been relatively
neglected by recent publications and demonstrates (contra Hawking et al) the continual
relevance and significance of philosophy for answering ultimate questions.
