One of the most influential philosophers of the Western  world in the scholastic tradition is Saint Thomas Aquinas. Saint Thomas Aquinas is a teacher in the Aristotelian tradition and expanded on theology and philosophy at the same time. To start, Thomas Aquinas was born in the year 1224 or 1224 and was the son of feudal parents who were in Italy under the reign of Fredrick the second. He grew up and got an education by the Catholic Church and he decided to become a Dominican Friar which his parents were not too pleased about. His parents and siblings held him in a year of captivity to try and prevent him from becoming a friar. Alas, this was to no avail because after the year of captivity Thomas Aquinas went to Paris to study under other notable Dominican Friars who were renown scholars. Thomas Aquinas acknowledged the church fathers before him with their Platonist views, but the university within Paris was having an Aristotelian revolution which lead to the spread of Aristotle’s works. He then got his license to  teach theology from the school in Paris around 1256. He then proceeded to act as a theological teacher and advisor in Rome for the next ten years. He went on to debate and prove his philosophy and theology over the Augustine and Platonist views that were held by some within and outside of the Church. At this time he was also writing down his works into books and texts. He then went on to serve the pope and further Aristotelian thought within Europe and the Church. He died on his way to serve the pope in 1274. Thomas Aquinas furthered philosophy and in my opinion I would argue that he is the “completion” of Aristotle. Thomas Aquinas is known for making the Five proofs to know God exists. These proofs are known as : motion, efficient cause, possibility and necessity, gradation, and design. All the methods go really in depth and takes a note from Aristotle’s metaphysics. Aside from the five proofs, Thomas Aquinas is known for furthering epistemological claims again by showing how man is made to know things and how it is in a mans nature to know truth. In addition, Thomas Aquinas furthers ethics and what we as people ought to do under the natural and the divine law. Also, Thomas Aquinas furthered the natural law concept proposed by Aristotle himself. Thomas furthers politics and what we ought to do as well. Surprisingly, Thomas Aquinas furthered psychology by talking and explaining the human intellect and mind and how it can and does operate. Thomas Aquinas being a doctor of the Catholic Church is a large accomplishment in it self, but the philosophy that Thomas Aquinas furthered is so influential to the world today.
