17. Mind and Body / A. Mind-Body Dualism / 5. Parallelism

2596	Maybe mind and body are parallel, like two good clocks

			Full Idea: Two clocks in perfect agreement must be by natural influence, or the control of a craftsman, or their perfect construction at the beginning. Only the third way (of "preestablished harmony" by God) is possible.
			From: Gottfried Leibniz (The Nature and Communication of Substance [1690], p.121)
			A reaction: Presumably 'natural influence' would cover the possibility that (unnoticed by you, apparently) one clock is attached to the other clock at the relevant points. If they are unconnected, presumably they are quite unaware of one another's existence.

28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof

2595	If the universe is a perfect agreement of uncommunicating substances, there must be a common source

			Full Idea: The perfect agreement of so many substances which have no communication whatever with each other can only come from a common source.
			From: Gottfried Leibniz (The Nature and Communication of Substance [1690], p.120)
