Stephen C. Pepper describes the Milesian School of philosophy as the first self-conscious world theory in European thought.
They sought the material principle, or arche, behind all things, and the method of its origin and disappearance. The pre-Socratics saw the world as a cosmos, an ordered arrangement that could be understood via rational inquiry.
In their effort to make sense of the cosmos, they coined new terms and concepts such as rhythm, symmetry, analogy, deductionism, reductionism, and others.
