Description:'The living body, as the Helmholtz of the 1860’s conceived it, was a physical structure the behaviour of which could be characterized in terms of mathematical laws. As such, it constituted a medium through which impulses from the external world were conveyed to the mind. Whilst nerves were conveyors of sensory stimulations, it was the function of a physiologically-inaccessible mind to arrive at judgements regarding nature. Mind and sense organs thereby formed two elements of a perceptual system that retained a distinct separation between the immediate physiological conditions of sensation and their (physiologically-undetermined) apprehension (Lenoir 1993, 123-125; Turner 1994, 73-80).'
