Wertz,Jr. he accepted view today among many, both inside and outside the Catholic Church, is that St. Thomas Aquinas (A.D. 1225-74) was an TAristotelian and as such an opponent of Plato (427-347 B.C.) . The truth, however, is that Thomas Aquinas actually devoted much of his adult life to defending the Christian fa ith from being subverted by the philosophy of Aristotle (384-322 B.C.) , which was rapidly establish ing its hegemony over the intellectual thought of his day, and that through the influence of St. Augustine (A.D. 354-430), he adopted the method and most crucial conceptions of Plato's philosophy. The reason it is important to establish that Aquinas is not an Aristotelian, is that Aristotle's philosophy is contrary not only to the Christian fa ith, but also to true science. During Aquinas' time, a number of Popes, recognizing that the works of Aristotle, which had newly become available in Europe by way of the Arabs, were contrary to the Christian fa ith, had on several occasions fo rbidden their being read in the schools. But a simple ban on the reading of Aristotle's works was obviously insuffi cient, and may very well have even fu eled the crisis. Therefore, in order to effectively combat the influence of Aristotle, especially as his ideas were put into circulation through the writ ings of A verroes (A.D. 1126-98), Pope Urban IV entrusted the defense of the Christian fa ith against the influ ence of the philosophy of Aristotle, to Thomas Aquinas. This article is based upon a speech pre pared fo r and read to a convention sponsored by the Ibero-American Soli darity Movement (MSIA) in Tlaxcala, Mexico on May 28, 1992.

For some of the doctrines of the Summa Theologica that "this manner of speaking is the heathens are spurious imitations or superstitious common among the Platonists, with whose doctrines inventions, which we must be careful to avoid when Augustine was imbued; and the fa ilure to refer to this we renounce the society of heathens."

Later in the same book Aristotle writes: Aristotle's terminology on others, has therefore misun " 'participation,' as we have said before, is nothing." derstood Aquinas' method. If one were to classify Aquinas as being in any current of thought, one would have to consider him an Augustin Aquinas' Method as Dialogue ian. Aquinas makes no criticism of Plato's philosophy Related to Aquinas' adoption of these two Platonic con which was not already made explicitly or implicitly by ceptions is his employment of Plato's method of dialogue, Augustine. Therefore, it is accurate to say that Aquinas as opposed to Aristotle's logic. In the Summa Th eologica, employed the Platonic method as corrected by Augustine to Aquinas' method is to present a negative thesis fo llowed amend those doctrines of Aristotle which were contrary by every conceivable argument that could be mustered to the Christian fa ith. in its defense.

Finally, he re Plato's Ideas and sponds to each of the objections, which had been ad The Notion of vanced in support of the thesis under consideration. Obviously, this is not the method of syllogism. With Participation respect to each topic under discussion, Aquinas enters AQUINAS, LIKE St. Au into a dialogue with all those who have put fo rward gustine before him, adopted an argument contrary to the truth. Like Plato in his two of Plato's most impor dialogues, Aquinas then derives the truth from the pro tant conceptions, both of cess of negating these fa lse assertions.
