"He (Haskell) confuted the theories of Sir Charles Bell and Marshall Hall as to the sensory and motor functions of the spinal nerves, believing that physiologists overlooked the existence of a spiritual principle within the body and that 'the real cause of the production of a given phenomenon, is mental instead of physical." [Kelly & Burrage].
