What theories did Thomas Aquinas propose to conclude that humans are creature of god?

Answer 1

To understand the crucial importance of this controversy for Western thought, it is necessary to consider the context in which it occurred. Before the time of Aquinas, Western thought had been dominated by the philosophy of Saint Augustine, the Western church's great Father and Doctor of the 4th and 5th centuries, who taught that in the search for truth people must depend upon sense experience. Early in the 13th century the major works of Aristotle were made available in a Latin translation, accompanied by the commentaries of Averroës and other Islamic scholars. The vigor, clarity, and authority of Aristotle's teachings restored confidence in empirical knowledge and gave rise to a school of philosophers known as Averroists. Under the leadership of Siger de Brabant, the Averroists asserted that philosophy was independent of revelation.

Averroism threatened the integrity and supremacy of Roman Catholic doctrine and filled orthodox thinkers with alarm. To ignore Aristotle, as interpreted by the Averroists, was impossible; to condemn his teachings was ineffectual. He had to be reckoned with. Albertus Magnus and other scholars had attempted to deal with Averroism, but with little success. Aquinas succeeded brilliantly.

Reconciling the Augustinian emphasis upon the human spiritual principle with the Averroist claim of autonomy for knowledge derived from the senses, Aquinas insisted that the truths of faith and those of sense experience, as presented by Aristotle, are fully compatible and complementary. Some truths, such as that of the mystery of the incarnation, can be known only through revelation, and others, such as that of the composition of material things, only through experience; still others, such as that of the existence of God, are known through both equally. All knowledge, Aquinas held, originates in sensation, but sense data can be made intelligible only by the action of the intellect, which elevates thought toward the apprehension of such immaterial realities as the human soul, the angels, and God. To reach understanding of the highest truths, those with which religion is concerned, the aid of revelation is needed. Aquinas's moderate realism placed the universals firmly in the mind, in opposition to extreme realism, which posited their independence of human thought. He admitted a foundation for universals in existing things, however, in opposition to nominalism and conceptualism.
