Chapter XVIII

, "The Automaton Theory: its Genesis."

We owe the doctrine of parallelism, in its original form, to Spinoza. It was elaborated by W. K. Clifford, and to him the modern interest in the subject is largely due. The whole subject is discussed at length in my "System of Metaphysics," Chapters XIX-XXI. The titles are: "The Automaton Theory: Parallelism," "What is Parallelism?" and "The Man and the Candlestick." Clifford's doctrine is presented in a new form in Professor Strong's recent brilliant work, "Why the Mind has a Body" N.Y., 1903.

Section 38. See "System of Metaphysics," Chapter XXIV , "The Time and Place of Sensations and Ideas."
