And just because both these movements are within, and necessary to, one and the same complete Church, they can be and are different from each other. Hence the following book would condemn itself to pompous unreality were it to mimic official caution and emphasis, whilst ever unable to achieve official authority. It prefers to aim at a layman’s special virtues and function: complete candour, courage, sensitiveness to the present and future, in their obscurer strivings towards the good and true, as these have been in their substance already tested in the past, and in so far as such strivings can be forecasted by sympathy and hope. And I thus trust that the book may turn out to be as truly Catholic in fact, as it has been Catholic in intention; I have striven hard to furnish so continuous and copious a stream of actions and teachings of Christian saints and sages as everywhere to give the reader means of correcting or completing my own inferences; and I sincerely submit these my own conclusions to the test and judgment of my fellow-Christians and of the Catholic Church. * * * * * My obligations to scholars, thinkers and great spiritual souls are far too numerous and great for any exhaustive recognition. Yet there are certain works and persons to whom I am especially indebted; and these shall here be mentioned with most grateful thanks. In my Biographical and Critical Part Second, I have had, in Genoa itself, the help of various scholars and friends. Signor Dottore Ridolfo de Andreis first made me realize the importance of Vallebona’s booklet. Padre Giovanni Semeria, the Barnabite, put me in touch with the right persons and documents. The Cavallière L. A. Cervetto, of the Biblioteca Civica, referred me to many useful works. The Librarian of the Biblioteca della Missione Urbana copied out for me the inventory of St. Catherine’s effects. And Signor Dottore Augusto Ferretto, of the Archivio di Stato, made admirably careful, explicitated copies for me, from the originals, so full of difficult abbreviations, of the long series of legal documents which are the rock-bed on which my biography is built. The courteous help of the Head Librarian of the Genoese University Library extended to beyond Genoa. For it was owing to his action, in conjunction with that of the Italian Ministry, of the English Embassy in Rome, and of the British Museum Authorities, that the three most important of the manuscripts of St. Catherine’s life were most generously deposited for my use at the latter institution. I was thus enabled to study my chief sources at full leisure in London. The Rev. Padre Calvino, Canon Regular of the Lateran, made many kind attempts to trace any possible compositions concerning St. Catherine among the Venerable Battista Vernazza’s manuscripts, preserved by the spiritual descendants of Battista’s Augustinian Canonesses in Genoa; it was not his fault that nothing could be found.
