Thomas Aquinas

 

St Thomas Aquinas (1225 to 1274) 

 Aquinas went to the University of Naples where he came into contact with the Order of Preachers or Dominicans. (He became a Dominican). Aquinas went on to study in Cologne with Albert the Great -- it was this association that introduced to Aristotelian philosophy. . He sought to employ rational argumentation in defense of Christian theology. He espoused the metaphysical teachings of Aristotle. Religious reasoning. Thomas Aquinas asserted that theology was a science in which careful application of reason would yield observable proof of theoretical knowledge.

  Among his writings are works easily recognizable as philosophy. He also wrote several commentaries on Aristotle. Thomas Aquinas sought to make a distinction between philosophy and theology:

“. . .the believer and the philosopher consider creatures differently. The philosopher considers what belongs to their proper natures, while the believer considers only what is true of creatures insofar as they are related to God, for example, that they are created by God and are subject to Him, and the like” (Summa contra gentiles, bk II, chap. 4).


“. . .it should be noted that the different ways of knowing (ratio cognoscibilis) give us different sciences. The astronomer and the natural philosopher both conclude that the world is round, but the astronomer does this through a mathematical middle that is abstracted from matter, whereas the natural philosopher considers a middle lodged in matter. Thus there is nothing to prevent another science from treating in the light of divine revelation what the philosophical disciplines treat as knowable in the light of human reason” (Summa theologiae, Ia, q. 1, a., ad 2).

Thomas Aquinas devoted much attention to the operation of nature believing that through nature God can be known analogically through the created world.

Thomas Aquinas – Existence of God
Thomas Aquinas applied this philosophical discourse to his Five Ways to Prove the Existence of God: 1) Motion; 2) Causation; 3) Contingency; 4) Goodness; 5) Design.

The first way was clearly indicative of his reasoning:
  • There is something moving
  • Everything that moves is put into motion by something else.
  • But this series of antecedent movers cannot reach back infinitely.
  • Therefore, there must be a first mover (which is God.)
