In a rather well-known article published half a century ago Michael Foster argued that modern science is rooted in the Christian doctrine of creation. Ancient science, on the other hand, was, according to Foster, the product of Greek metaphysics. The goal of ancient science was the definition of the essence of its object of investigation. The Greeks assumed that the essence of an object was its form and that the form of a thing was intelligible. The task of science, then, was to bring this intelligibility to light.
