The philosophical reflections contained in this book by one of the outstanding, scholarly and profound theologians in the Catholic Church today are reminiscent in quality, tone and style of the famous Pensees of Pascal. The author's thoughts on various aspects of man's approach to God and God's to man are restricted mainly to the province of natural theology and relate to such topics as ""The Origin of the Idea of God"", ""The Affirmation of God"", ""The Proof of God"", ""The Knowledge of God"", ""The Ineffable God"", ""The Search for God"" and ""God in Our Time"". Staunchly defending the traditional thomistic proof for God's existence on the purely rational plane, the author is more concerned, however, with the questions of its ontological grounding in the very nature of human knowing and its insufficiency to produce conviction in certain cases because the total personal context of the individual is ignored. The absurdity of certain modern psychologistic approaches to the origin of the idea of God and the de-humanizing consequences of atheistic humanism are pointed up in a striking manner. This is a book for Catholic and non-Catholic alike, for all who are interested in clarifying their views on the subject of man's approach to God by way of reason alone.
