A glance at this book’s index reveals the breadth of Merton’s interests, and the diversity of his correspondents. It can be helpful to follow a particular theme or person through the letters and down the years. Naturally, the letters reveal that Merton did not have the benefit of hind-sight nor the judgement of history, on some of the people and subjects in his writing. Given the times in which he wrote it is not surprising that some of the issues vital to his contemporaries and to him, are now seen to be less so to us. Nevertheless, Thomas Merton remains a compelling and illuminating letter writer.
