""This book contains a careful, thorough, and where necessary skeptical as regards doubtful evidence (especially in the case of Plato and the Old Academy) of the beginnings in European thought of the negative or apophatic way of thinking and its relations to more positive or kataphatic ways of thinking about God. One of its greatest strengths, perhaps the greatest, is that the author makes clear that none of the persons concerned, Hellenic, Jewish or Christian, was engaged in the pursuit of a philosophical abstraction, or the heaping of rhetorical superlatives on God. They were rather concerned to present the origin of the universe as an intimately present living reality which infinitely transcends our thought and speech. This, combined with careful attention to the varieties of negative theology and its relations with positive, and the particular difficulties experienced by the members of the various traditions involved, makes the book the best introduction to the negative theology available.""
