Possibly it is worth while here to give more than a passing notice to the ascent of the Nile in the seventeenth century, made by the noted Pedro Páez, a Spanish Jesuit. He left an account of it which Kircher published in his "Œdipus Ægyptiacus" but which James Bruce angrily described as an invention. Bruce claims that he himself was the first to explore the river. But Bruce followed Páez by at least 150 years. The question is discussed at length by two writers in the "Biographie universelle," under the titles "Bruce" and "Paez."

Páez was born at Olmeda in 1564. He entered the Society when he was eighteen years of age and was sent to Goa in 1588. He was assigned to attempt an entry of Abyssinia; to facilitate his work, he assumed the dress of an Armenian. He had to wait a year for a ship at Ormuz, and when, at last, he embarked he was captured by an Arab pirate, ill-treated and thrown into prison. As he was unable to procure a ransom, he spent seven years chained to the oar as a galley slave, but was finally set free and reached Goa in 1596. He was then employed in several missions of Hindostan, but again set out for Abyssinia which he reached in 1603. To acquaint himself with the language of the people he buried himself in a monastery of Monophysite monks, and then began to give public lessons in the city. His success as a teacher attracted attention, and he was finally called before the emperor, where his eloquence and correctness of speech captivated and ultimately helped to convert the monarch. A grant of land was given him at Gorgora where he built a church. The question of the sources of the Nile was frequently discussed, and in 1618 Páez ascended the river. He was thus the first modern European to make the attempt. He told the story in the two large octavos, which at the time of the Suppression could be found in most of the libraries of the Society. Bruce asserts, however, that nothing is said in these volumes about the discovery, and he accuses Kircher of imposture. But, says the writer in the "Biographie universelle," the fact is that between the account of Páez and that of Bruce there is scarcely any difference except in a few insignificant details; so that if Bruce is right, so also are Páez and Kircher. Páez explored the river as early as 1618, whereas Bruce arrived there only in 1772, that is 154 years later. "Bruce," says another writer "makes it clear that someone had preceded him and displays his temper in every line."

The great English work, "The Dictionary of National Biography," handles Bruce more severely. "He was in error," it says, "in regarding himself as the first European who had reached these fountains. Pedro Páez, the Jesuit, had undoubtedly done so in 1615, and Bruce's unhandsome attempt to throw doubt on the fact only proves that love of fame is not literally the last infirmity of noble minds, but may bring much more unlovely symptoms in its train. He was endowed with excellent abilities, but was swayed to an undue degree by self-esteem and thirst for fame. He was uncandid to those he regarded as rivals, and vanity and the passion for the picturesque led him to embellish minor particulars and perhaps in some instances to invent them. He delayed for twelve years the composition of his narrative and then dictated it to an amanuensis, indolently omitting to refer to the original journals and hence frequently making a lamentable confusion of facts and dates. His report is highly idealised and he will always be the poet of African travel." The book did not appear till 1790. The missionary success of Páez consisted in uniting schismatical Abyssinia to Rome in 1624. He died shortly afterwards, and, when the depraved Emperor Basilides mounted the throne in 1634, the Jesuit missionaries were handed over to the axe of the executioner. Páez, it may be remarked, was not the only one whom Bruce vilified. After Páez came the Portuguese Jesuit Jeronimo Lobo, a very interesting and lengthy account of whose daring missionary work may be found in the "Biographie universelle." The writer tells us that Lobo published his narrative in 1659, and that it was again edited by the Royal Society of London in 1688. Legrand translated it into French in 1728, and Dr. Samuel Johnson gave a compendious translation of it in 1734. The complete book was reprinted in 1798, and in the preface the editors take Bruce to task for his treatment of both Páez and Lobo. It is worthy of remark that the notice of "Bruce" in the "Encyclopedia Britannica" (ninth edition) does not say a single word either of Páez or Lobo, although both had attracted so much notice in the modern literary world.

It was due to the Jesuits that France established subventions for geographical research. In 1651 Martino Martini, kinsman of the celebrated Eusebio Kino, published his "Atlas Sinensis", which Richtoven described as "the fullest geographical description of China that we have." Kircher published his famous "China illustrata" in 1667. Verbiest was the imperial astronomer in China, and so aroused the interest of Louis XIV that he sent out six Jesuit astronomers at his own expense and equipped them with the finest instruments. One of these envoys, Gerbillon, explored the unknown regions north of China, and he, with Buvet, Régis and Jarton and others, made a survey of the Great Wall, and then mapped out the whole Chinese empire (1718). Manchuria and Mongolia as far as the Russian frontier and Tibet to the sources of the Ganges were included. The map ranks as a masterpiece even to-day. It consists of 120 sheets, and it has formed the basis of all the native maps made since then. De Halde edited all the reports sent to him by his brethren, and published them in his "Description géographique, historique, politique, physique et chronologique de l'empire de Chine et de la Tartarie chinoise." The material for the maps in this work was prepared by d'Anville, the greatest geographer of the time, but he was not a Jesuit. In addition to these works, were written fifteen volumes by the missionaries of Pekin about the history and customs of the Chinese, and published in Paris.

These Jesuit astronomers and geographers were associate members of all the learned societies of Europe, and were especially serviceable to those bodies in being able to determine the longitude and latitude of the places they described. Between 1684 and 1686 they fixed the exact position of the Cape of Good Hope and of Louveau in Siam. As early as 1645 Riccioli attempted to determine the length of a degree of longitude. Similar work was done by Thoma in China, Boscovitch and Maire in the Papal States, Leisganig in Austria; Mayer in the Palatinate, and Beccaria and Canonica in northwestern Italy. Veda published the first map of the Philippines about 1734. Mezburg and Guessman made maps of Galicia and Poland, Andrian of Carinthia, and Christian Meyer of the Rhine from Basle to Mainz. Riccioli, a distinguished reformer of cartography, published his "Almagestum novum", and his "Geographia et hydrographia reformata" as early as 1661. Kircher gave the world his "Arsmagnetica" and "Mundus subterraneus" about the same time, and made the ascent of Etna and Stromboli at the risk of his life, to measure their craters. His theory of the interior of the earth was accepted by Leibniz and by the entire Neptunist school of geology. He was the first to attempt to chart the ocean currents. Heinrich Scherer of Dillingen (1620-1704) devoted his whole life to geography, and made the first orographical and hydrographical synoptic charts. Johann Jacob Hemmer was the founder of the first meteorological society, which had contributors from all over the world. This list is sufficiently glorious.

Perhaps it might be noted here that these eminent men were not primarily seeking distinction or aiming at success in the sciences to which they devoted themselves. That consideration occupied only a secondary place in their thoughts and the glory they achieved was sought exclusively to enable them the more easily to reach the souls of men. But on the other hand, that motive inspired them with greater zeal in the prosecution of their work than a merely human purpose would have done. Assuredly, it would have been much more comfortable for Ricci and Schall and Verbiest and Grimaldi to be looking through telescopes in the observatories of Europe than at Canton or Pekin, where every moment they were in danger of having their heads cut off. As a matter of fact, after more than forty years of service for China's education in mathematics and astronomy, the only reward that Father Schall reaped was, as we have seen, to be dragged to court, though he was paralyzed and speechless, and to be condemned to be hacked to pieces.

It is quite true that the philosophers of the Society have never evolved any independent philosophical or theological thought, in the modern acceptation of that term. That is, they have never acted like the captain of a ship who would throw his charts and compass overboard, and insist that North is South because he thinks it so. The aim of philosophy is intellectual truth and not the extravagances of a disordered imagination. Contrary to the modern superstition, Catholic philosophers are not hampered in their speculations by authority, nor are they compelled in their study of logic, metaphysics and ethics to draw proofs from revelation. Philosophy is a human not a divine science, but on the other hand, Catholic philosophy is prevented from going over the abyss by the possession of a higher knowledge than unassisted human reason could ever attain. Thus protected, it speculates with an audacity, of which those who are not so provided can have no conception. For them philosophy runs through the whole theological course, and when Holy Scripture, the pronouncements of the Church, and the utterances of the Fathers have established the truth of the particular doctrine which is under consideration, then reason enters, and elevated, ennobled, fortified and illumined, it walks secure in the highest realms of thought. Three entire years are given to the explicit study of it, in the formation of the Jesuit scholastic, and it continues to be employed throughout his four or five years of theology. Both sciences are fundamental in the Society's studies, and it has not lacked honor in either. But as philosophy is subsidiary and ancillary, it will be sufficient to set forth what is said about the Society's theologians.

Dr. Joseph Pohle writing in "The Catholic Encyclopedia" tells us that controversial theology was carried to the highest perfection by Cardinal Bellarmine. Indeed, there is no theologian who has defended almost the whole of Catholic theology against the attacks of the Reformers with such clearness and convincing force. Other theologians who were remarkable for their masterly defence of the Catholic Faith were the Spanish Jesuit Gregory of Valencia (d. 1603) and his pupils Adam Tanner (d. 1635) and Jacob Gretser (d. 1625). Nor can there be any question that Scholastic theology owes most of its classical works to the Society of Jesus. Molina was the first Jesuit to write a commentary on the theological "Summa" of St. Thomas, and was followed by Cardinal Toletus and those other brilliant Spaniards, Gregory of Valencia, Suárez, Vasquez, and Didacus Rúiz. Suárez, the most prominent among them, is also the foremost theologian the Society of Jesus has produced. His renown is due not only to the fertility and wealth of his literary productions, but also to his clearness, moderation, depth and circumspection. He had a critic, both subtle and severe, in his colleague, Gabriel Vásquez. Didacus Rúiz wrote masterly treatises on God and the Trinity, as did Christopher Gilles; and they were followed by Harruabal, Ferdinand Bastida, Valentine Herice, and others whose names will be forever linked with the history of Molinism. During the succeeding period, John Præpositus, Caspar Hurtado, and Antonio Pérez won fame by their commentaries on St. Thomas. Ripalda wrote the best treatise on the supernatural order. To Leonard Lessius we owe some beautiful treatises on God and his attributes. Coninck made the Trinity, the Incarnation, and the Sacraments his special study. Cardinal John de Lugo, noted for his mental acumen and highly esteemed as a moralist, wrote on the virtue of Faith and the Sacraments of Penance and the Eucharist. Claude Tiphanus is the author of a classical monograph on the notions of personality and hypostasis, and Cardinal Pallavicini, known as the historiographer of the Council of Trent, won repute as a dogmatic theologian by several of his writings (XIV, 593-94).

With regard to moral theology, Lehmkhul tells us that in the middle of the eighteenth century there arose a man who was, so to say, a blessing of Divine Providence. Owing to the eminent sanctity which he combined with solid learning, he definitely established the system of moral theology which now prevails in the Church. That man was St. Alphonsus Maria Liguori, who was canonized in 1839, and declared a Doctor of the Church in 1871. In his youth he was imbued with the stricter principles of moral theology, but as he himself confesses, the experience of fifteen years of missionary life and careful study brought him to realize the falseness and the evil consequences of the system in which he had been educated, and the necessity of a change. He, therefore, took the "Medulla" of the Jesuit, Hermann Busembaum, subjected it to a thorough examination, confirmed it by internal reasons and external authority, and then published a work which was received with universal applause, and whose doctrine is entirely on Probabilistic principles. This approval and appropriation of Busembaum's teaching by one who has been made a Doctor of the Church is a sufficient vindication of the doctrine of Probabilism, for which the Society suffered so much, and is at the same time a magnificent tribute to the greatness of Busembaum, "whose book," Lehmkuhl contents himself with saying, "was widely used," whereas forty editions of it had been issued during the author's own life, which happened to be an entire century before the publication of Liguori's great work. Busembaum's "Medulla" was printed in 1645, and Liguori's "Moral Theology" in 1748. Up to 1845, there were 200 editions of Busembaum; that is, one edition for every year of its existence. In the history of moral theology Sánchez, Layman, Azor, Castro Palao, Torres, Escobar also may be cited as leading lights.

In Scripture there are the illustrious names of Maldonado, Ribera, Prado, Pereira, Sancio and Pineda. Of the saintly Cornelius a Lapide (Vanden Steen) a Protestant critic, Goetzius, said in 1699: "He is the most important of Catholic Scriptural writers." His "Commentary of the Apocalypse" has been translated into Arabic. In ascetical theology, St. Ignatius is a leader in modern times; and his "Spiritual Exercises" form a complete system of asceticism. With him are a great number of his sons, whose names are familiar in every religious house, such as Bellarmine, Rodríguez, Alvarez de Paz, Gaudier, da Ponte, Lessius, Lancicius, Surin, Saint-Jure, Neumayr, Dirckink, Scaramelli, Nieremberg and many others. Finally, it can not be denied that the Society has hearkened to the second rule of the Summary of its Constitutions, which is read publicly and with an unfailing regularity every month of the year, in every one of its houses throughout the world, namely: that "the End of this Society is not only to attend to the salvation and perfection of our own souls, with the divine grace, but with the same, seriously to employ ourselves in procuring the salvation and perfection of our neighbor."
