" Leibniz is supposed to help provide answers to these questions. His philosophy revolves around the concept of monads, a term drawn from calculus indicating something irreducible and individual. A monad is like a soul or an atom, except that it contains within itself all ideas about the external world, including the relationships between objects on the time and space continuum, including itself. Harvey singles out the following passage from Leibniz's writings presumably because it speaks to his quandary at the Oxford Rover plant."
