“When we say that the mind is a function of the brain, we are therefore to understand that in exact scientific truth we can mean nothing more than this: That physical and physiological changes go on, seriatim, side by side with changes in psychic experience; or vice versa, that psychic changes run parallel, pari passu, with physiological changes in the brain and the other neural tissues.”
— George Holmes HowisonThe Limits of Evolution, and Other Essays, Illustrating the Metaphysical Theory of Personal Ideaalism (1905)
