This is the second edition of David Hartley's (1705-1757) 'Observations on Man', the first was published in 1749. A quarto edition was also published in the same year as the present copy. What differs from this edition to the original, is that it was edited by David Hartley's eldest son, also named David Hartley (1731-1813).

'Observations' is "a seminal attempt to extend Newtonian science to the study of human nature" (ODNB). Hartley argued that the body's component particales are "subjected to the same subtle laws" (1, prop. 9) as are all other material entities.These subtle laws are those Newton hinted at in the 'Queries' to his Opticks, and upon which Hales based his chemical theory. Hartley's doctrine of vibrations is thus a neurophysiology constructed on the basis of Newtonian speculative physics: when sound strikes the eardrum or light the eye, the spheres of attraction and repulsion surrounding the particles in the relevant nerves vibrate, and the vibrations move along the nerves and into the brain, where the signals travel both to the region dedicated to the sensory modality and also to regions that are associated with it. This last point is crucial, for without such 'joint impression' of signals from different sensory modalities, an organism would be unable to co-ordinate vision with hearing or either with movement (ODNB).
