SAINT THOMAS AQUINAS

St. Thomas Aquinas was an Italian Dominican theologian and the foremost medieval Scholasticist. His doctrinal system and the explanations and developments made by his followers are known as Thomism. He is nevertheless recognized by the Roman Catholic Church as its foremost Western philosopher and theologian.

EARLY YEARS

Thomas was born to parents who were in possession of a modest feudal domain on a boundary constantly disputed by the emperor and the pope. Thomas was placed in the monastery of Monte Cassino near his home as an oblate (i.e., offered as a prospective monk) when he was still a young boy; his family doubtless hoped that he would someday become abbot to their advantage. In 1239, after nine years in this sanctuary of spiritual and cultural life, young Thomas was forced to return to his family when the emperor expelled the monks because they were too obedient to the pope. He was then sent to the University of Naples, recently founded by the emperor, where he first encountered the scientific and philosophical works that were being translated from the Greek and the Arabic.

In this setting Thomas decided to join the Friars Preachers, or Dominicans, a new religious order founded 30 years earlier, which departed from the traditional paternalistic form of government for monks to the more democratic form of the mendicant friars (i.e., religious orders whose corporate as well as personal poverty made it necessary for them to beg alms) and from the monastic life of prayer and manual labour to a more active life of preaching and teaching. A dramatic episode marked the full significance of his decision. His parents had him abducted on the road to Paris, where his shrewd superiors had immediately assigned him so that he would be out of the reach of his family but also so that he could pursue his studies in the most prestigious and tur-bulent university of the time.

STUDIES IN PARIS 

Thomas held out stubbornly against his family despite a year of captivity. He was finally liberated and in the autumn of 1245 went to Paris to the convent of Saint-Jacques, the great university centre of the Dominicans; there he studied under Albertus Magnus, a tremendous scholar with a wide range of intellectual interests.

When Thomas Aquinas arrived at the University of Paris, the influx of Arabian-Aristotelian science was arousing a sharp reaction among believers; and several times the church authorities tried to block the naturalism and rationalism that were emanating from this philosophy and, according to many ecclesiastics, seducing the younger generations. Thomas did not fear these new ideas, but, like Albertus Magnus (and Roger Bacon, also lecturing at Paris), he studied the works of Aristotle and eventually lectured publicly on them.

During the summer of 1248, Aquinas left Paris with Albertus, who was to assume direction of the new faculty established by the Dominicans at the convent in Cologne. He remained there until 1252, when he returned to Paris to prepare for the degree of master of theology. After taking his bachelor’s degree, he received the licentia docendi (“license to teach”) at the beginning of 1256 and shortly afterward finished the training necessary for the title and privileges of master. Thus, in the year 1256 he began teaching theology in one of the two Dominican schools incorporated in the University of Paris. 

LATER YEARS 

In 1259 Thomas was appointed theological adviser and lecturer to the papal Curia, then the centre of Western humanism. He returned to Italy, where he spent two years at Anagni at the end of the reign of Alexander IV and four years at Orvieto with Urban IV. From 1265 to 1267 he taught at the convent of Santa Sabina in Rome and then, at the request of Clement IV, went to the papal Curia in Viterbo. Suddenly, in November 1268, he was sent to Paris, where he became involved in a sharp doctrinal polemic that had just been triggered off.The works of Averroës, the outstanding representative of Arabic philosophy in Spain, who was known as the great commentator and interpreter of Aristotle, were just becoming known to the Parisian masters. 

Averroës asserted that the structure of religious knowledge was entirely heterogeneous to rational knowledge: two truths—one of faith, the other of reason—can, in the final analysis, be contradictory. This dualism was denied by Muslim orthodoxy and was still less acceptable to Christians. With the appearance of Siger of Brabant, however, and from 1266 on, the quality of Averroës’s exegesis and the wholly rational bent of his thought began to attract disciples in the faculty of arts at the University of Paris. Thomas Aquinas rose in protest against his colleagues; nevertheless, the parties retained a mutual esteem.

In the course of this dispute, the very method of theology was called into question. According to Aquinas, reason is able to operate within faith and yet according to its own laws. The mystery of God is expressed and incarnate in human language; it is thus able to become the object of an active, conscious, and organized elaboration in which the rules and structures of rational activity are integrated in the light of faith. In the Aristotelian sense of the word, then (although not in the modern sense), theology is a “science”; it is knowledge that is rationally derived from propositions that are accepted as certain because they are revealed by God. The theologian accepts authority and faith as his starting point and then proceeds to conclusions using reason; the philosopher, on the other hand, relies solely on the natural light of reason. Thomas was the first to view theology expressly in this way or at least to present it systematically, and in doing so he raised a storm of opposition in various quarters.

The logic of Aquinas’s position regarding faith and reason required that the fundamental consistency of the realities of nature be recognized. A physis (“nature”) has necessary laws; recognition of this fact permits the construction of a science according to a logos (“rational structure”). Thomas thus avoided the temptation to sacralize the forces of nature through a naïve recourse to the miraculous or the Providence of God. For him, a whole “supernatural” world that cast its shadow over things and men, in Romanesque art as in social customs, had blurred men’s imaginations. Nature, discovered in its profane reality, should assume its proper religious value and lead to God by more rational ways, yet not simply as a shadow of the supernatural. 

This understanding is exemplified in the way that Francis of Assisi admired the birds, the plants, and the Sun.Although he was an Aristotelian, Thomas was certain that he could defend himself against a heterodox interpretation of “the Philosopher,” as Aristotle was known. Thomas held that human liberty could be defended as a rational thesis while admitting that determinations are found in nature. In his theology of Providence, he taught a continuous creation, in which the dependence of the created on the creative wisdom guarantees the reality of the order of nature. God moves sovereignly all that he creates, but the supreme government that he exercises over the universe is conformed to the laws of a creative Providence that wills each being to act according to its proper nature. This autonomy finds its highest realization in the rational creature: humans are literally self-moving in their intellectual, volitional, and physical existence. Their freedom, far from being destroyed by their relationship to God, finds its foundation in this very relationship.

In January 1274 Thomas was personally summoned by Gregory X to the second Council of Lyons, which was an attempt to repair the schism between the Latin and Greek churches. On his way he was stricken by illness; he stopped at the Cistercian abbey of Fossanova, where he died on March 7.
