The analysis of great philosophical works reveals that their scientific attempt is also significant. In fact, philosophy is the predecessor of modern science. Until the medieval ages, the separation between philosophy and science was not this clear as is. However, after the rebellious acts of papal authorizes in medieval Europe the severe conflict between science and theology began during the 17th century when the era of historical unfriendliness between philosophy, and science began.
Unlike theology both philosophy and science follow logical methods to gather knowledge. However, the methods they use are case different at their core. The line that separates science and philosophy is the inner workings of science which tell us the facts of the universe, in contrast to philosophy which helps us interpret them. When the segregation became commonplace, philosophers refocused their approach to science where some, like Hume, questioned the validity of inductive reasoning used in science, and others sought to understand the workings of science itself – a sub-branch called philosophy of science.
