And later still came the discovery of the apparently hopeless complication of the records of Catherine’s life and doctrine, and how these had never been seriously analyzed by any trained scholar, since their constitution into a book in 1552. Much critical work at Classical and Scriptural texts and documentary problems had, by now, whetted my appetite to try whether I could not at last bring stately order out of this bewildering chaos, by perhaps discovering the authors, dates and intentions of the various texts and glosses thus dovetailed and pieced together into a very Joseph’s coat of many colours, and by showing the successive stages of this, most original and difficult, Saint’s life and legend. All this labour would, in any case, help to train my own mind; and it would, if even moderately successful, offer one more detailed example of the laws that govern such growths, and of the critical method necessary for the tracing out of their operation. But the strongest motive revealed itself, in its full force, later than all those other motives, and ended by permeating them all. The wish arose to utilize, as fully as possible, this long, close contact with a soul of most rare spiritual depth,--a soul that presents, with an extraordinary, provocative vividness, the greatness, helps, problems and dangers of the mystical spirit. I now wanted to try and get down to the driving forces of this kind of religion, and to discover in what way such a keen sense of, and absorption in, the Infinite can still find room for the Historical and Institutional elements of Religion, and, at the same time, for that noble concentration upon not directly religious contingent facts and happenings, and upon laws of causation or of growth, which constitutes the scientific temper of mind and its specific, irreplaceable duties and virtues. Thus, having begun to write a biography of St. Catherine, with some philosophical elucidations, I have finished by writing an essay on the philosophy of Mysticism, illustrated by the life of Caterinetta Fiesca Adorna and her friends. * * * * * The book’s chief peculiarities seem to spring inevitably from its fundamental standpoint: hence their frank enumeration may help towards the more ready comprehension of the work.
