David Hartley

Hartley, David, 1705–57, English physician and philosopher, founder of associational psychology. In his Observations on Man (2 vol., 1749) he stated that all mental phenomena are due to sensations arising from vibrations of the white medullary substance of the brain and spinal cord. He conceived the whole mind as resulting from the association of simple sensations. See associationism.
