Observations on Man; Notes and Additions to Dr. Hartley's Observations on Man

A handsome example of the fourth edition of David Hartley's important philosophical work 'Observations on Man', uniformly bound alongside the third edition of Pistorius's study of Hartley and his work. Present here is the 1801 fourth edition of 'Observations on Man', complete in two volumes, alongside the single volume 1801 third edition of 'Notes and Additions to Dr. Hartley's Observations on Man' by Hermann Andreas Pistorius. 'Observations on Man' by David Hartley is a major philosophical work putting forth two central theories from the author: the doctrine of vibrations and the doctrine of associations. These ideas surround the connection between the human body and the mind, and with the duty and expectations of mankind. The work was first published in 1749 by Samuel Richardson. The second work present here is the third edition of Hermann Andreas Pistorius's critical study of Hartley's work, in which he also includes a biography of the author.
