The Scottish philosophy of Thomas Reid and his successors believed that David Hume's scepticism was no more than the genuine outcome of Locke's sensationalist appeal to experience when ripened or forced on by the immaterialism of Bishop Berkeley - God and the soul alone; not God, world and soul.
He is realistic and idealistic, individualistic and universalistic, monistic and dualistic, sensationalist and intellectualist, naturalist and supernaturalist, rationalist and mystic, gnostic and agnostic. He is the prince of the Vermittler in philosophy, ethics, religion and theology.
Locke is thus a sensationalist and empiricist, but incompletely, and without perfect coherence.
Flint that while materialism requires sensationalist psychology, yet the psychology in question allows no valid inference to matter, and therefore destroys materialism.
