The author examines the problems of religion critically from the standpoint of biology, psychology, metaphysics, etc. He makes a minute survey of metaphysical, psychological and political thinkers, their attitude towards religious concepts and a critical estimate of science and scientific investigations and in the light of these he builds up his own rational system of thought.

Throughout the ages one of the central topics in philosophy of religion has been the rationality of theistic belief. This book proposes that parties on both sides of this debate might shift their attention in a different direction, by focusing on the question of whether it is rational to be a religious theist. Explaining that having theistic beliefs is primarily a cognitive affair but being a religious theist involves a whole way of life that includes one's beliefs, Golding argues that it can be pragmatically rational to be a religious theist even if the evidence for God’s existence is minimal. The argument is applied to the case of Judaism, articulating what is involved in religious Judaism and arguing that it is rationally defensible to be a religious Jew. The book concludes with a discussion of whether a similar argument might be constructed for other versions of religious theism such as Christianity or Islam, and for non-theistic religions such as Taoism or Buddhism. Joshua Golding offers a carefully wrought explanation of how it can be rational for someone to live a religious life, in particular (but not necessarily only), a traditional Jewish life.

Every known religious or explicitly irreligious outlook is contested by large contingents of informed and reasonable people. Many philosophers have argued that reflection on this fact should lead us to abandon confident religious or irreligious belief and to embrace religious skepticism. John Pittard critically assesses the case for such disagreement-motivated religious skepticism. While the book focuses on religious disagreement, it makes a number of significant contributions to the more general discussion of the rational significance of disagreement as well.

Kant's Moral Religion argues that Kant's doctrine of religious belief if consistent with his best critical thinking and, in fact, that the "moral arguments"--along with the faith they justify--are an integral part of Kant's critical thinking.
