The renaissance and its enormous output of art, writing, and inquiry, inevitably led to the Age of Enlightenment. The discovery that the world was round and not flat, that the earth was not the center of the universe and the radical shift in religious beliefs because of the reformation lead to an age of questioning the church's beliefs and teachings. Reason and rational thought were its ideals. What is truth? Can it be studied, measured, poked & prodded — can it be revealed through thinking, study, dissection, measurement, rather than scripture and a high priest? It was the mathematician, the philosopher and the printing press that drove this movement.
