THE LITTLE BOOK OF ETERNAL WISDOM is among the best of the writings of Blessed Henry Suso, a priest of the Order of St. Dominic, who lived a life of wonderful labours and sufferings, and died in the Fourteenth century with a reputation for sanctity which the Church has solemnly confirmed. Gregory XVI. granted to the whole Order of St. Dominic the privilege of celebrating his office, and of offering the Mass yearly in his honour, appointing the Second of March for his festival. The Order of St. Dominic, known in the Church both as the Order of Truth and the Order of Preachers, so rich in pontiffs, martyrs, and confessors, is also illustrious for its theologians, its ascetic writers, its great masters of the spiritual life. Its mystic theologians stand in the first rank of those who have scaled the wondrous heights of sublime perfection. Not only have they stood on the mountain tops of the spiritual life, but they have pointed out, with a clearness surpassed by no other writers, the path of ascent, marking for the unwary its every danger. The wiles of the enemy are exposed; where, when, and how he seeks to accomplish our ruin. Our defence is first outlined, and then given in detail. The source of strength is pointed out, and thus the perilous journey may safely be made.

St. Alphonsus writes: a single bad book will be sufficient to cause the destruction of a monastery. Pope Pius XII wrote in 1947 at the beatification of Blessed Maria Goretti: There rises to Our lips the cry of the Saviour: 'Woe to the world because of scandals ' (Matthew 18:7). Woe to those who consciously and deliberately spread corruption-in novels, newspapers, magazines, theaters, films, in a world of immodesty We at St. Pius X Press are calling for a crusade of good books. We want to restore 1,000 old Catholic books to the market. We ask for your assistance and prayers. This book is a photographic reprint of the original. The original has been inspected and some imperfections may remain. At Saint Pius X Press our goal is to remain faithful to the original in both photographic reproductions and in textual reproductions that are reprinted. Photographic reproductions are given a page by page inspection, whereas textual reproductions are proofread to correct any errors in reproduction.
