Thomas Merton (1915-1968) is arguably the most influential American Catholic author of the twentieth century. His autobiography, The Seven Storey Mountain, has millions of copies and has been translated into over fifteen languages. He wrote over sixty other books and hundreds of poems and articles on topics ranging from monastic spirituality to civil rights, nonviolence, and the nuclear arms race.

After a rambunctious youth and adolescence, Merton converted to Roman Catholicism and entered the Abbey of Gethsemani, a community of monks belonging to the Order of Cistercians of the Strict Observance (Trappists), the most ascetic Roman Catholic monastic order.

The twenty-seven years he spent in Gethsemani brought about profound changes in his self-understanding. This ongoing conversion impelled him into the political arena, where he became, according to Daniel Berrigan, the conscience of the peace movement of the 1960's. Referring to race and peace as the two most urgent issues of our time, Merton was a strong supporter of the nonviolent civil rights movement, which he called "certainly the greatest example of Christian faith in action in the social history of the United States." For his social activism Merton endured severe criticism, from Catholics and non-Catholics alike, who assailed his political writings as unbecoming of a monk.

During his last years, he became deeply interested in Asian religions, particularly Zen Buddhism, and in promoting East-West dialogue. After several meetings with Merton during the American monk's trip to the Far East in 1968, the Dali Lama praised him as having a more profound understanding of Buddhism than any other Christian he had known. It was during this trip to a conference on East-West monastic dialogue that Merton died, in Bangkok on December 10, 1968, the victim of an accidental electrocution. The date marked the twenty-seventh anniversary of his entrance to Gethsemani.

The Wisdom of the Desert was one of Thomas Merton's favorites among his own books―surely because he had hoped to spend his last years as a hermit.

The personal tones of the translations, the blend of reverence and humor so characteristic of him, show how deeply Merton identified with the legendary authors of these sayings and parables, the fourth-century Christian Fathers who sought solitude and contemplation in the deserts of the Near East.

The hermits of Screte who turned their backs on a corrupt society remarkably like our own had much in common with the Zen masters of China and Japan, and Father Merton made his selection from them with an eye to the kind of impact produced by the Zen mondo.
