The ancient Greeks understood philosophy as a search for an explanation by searching for the stoicheon, (primordial source). Some would think that they just led the people into confusion, making them not to believe in the Greek gods as the source of all things. Donald .
Palmer said: "But to the Greeks of the 5th century, the pre-Socratic philosophers had left a legacy of confusion. The only thing the philosophers had succeeded in doing was to undermine the traditional religious and moral values, leaving nothing substantial in their place." .
The search for the primordial source did not end in the ancient period but continued by some medievalists. An attempt of joining Christianity and Greek thought occurred in the Middle Ages3. Considering the attempt of the pre-Socratics, their way of thinking has been a big help for the medieval thinkers in searching for the primordial source. After realizing the error in the attempts of the ancient Greeks, the medievalists may have thought that maybe it was the other way around. If the stoicheon is not an element (water, air, fire, etc.) then it is a being that has the capacity to create, a being that creates from nothing. What makes this age distinct from the other was that the medieval period was the age when Christianity started to bloom. It was because of Constantine's toleration that Christianity became the dominating religion. It was also an age when philosophy was understood differently from the way it is understood. Philosophy was but a tool in searching for the primordial source.
Medieval thinkers believed in the existence of a Supreme Being. Comparing the Middle Ages to the other eras, this age has been known for its search for the rational explanation to God. Some philosophers taught that God will never be explained but understood only by faith. Some thinkers taught that God can be proven by reason alone. Some philosophers taught that both faith and reason could aid us in the knowledge of God.
