To define and explore contemporary philosophical critiques of Christian belief is the purpose of this book, which arises out of a conference held at Princeton Theological Seminary. In a frank and extensive confrontation, outstanding philosophers and theologians met to search for greater clarity on some important issues in the philosophy of religion. The book contains the papers written for the conference, the prepared criticism, and excerpts from the debates. The discussions revolved around the experiential grounds of religious belief; the question as to what conclusions may legitimately be drawn from religious experience; the "emptiness" or otherwise of Christian belief and ethic in the modern world; the Freudian explanation of faith; and the Barthian defense of Christianity.
