Observations on Man

Name: Observations on Man
Author: David Hartley (philosopher)

Observations on Man, his Frame, his Duty, and his Expectations is 18th-century British philosopher David Hartley's major work. Published in two parts in 1749 by Samuel Richardson, it puts forth Hartley's principal theories: the doctrine of vibrations and the doctrine of associations. The first part of the text deals with the frame of the human body and mind, and their mutual connections and influences, the second with the duty and expectations of mankind.

“With respect to animal diet, let it be considered, that taking away the lives of animals, in order to convert them into food, does great violence to the principles of benevolence and compassion. This appears from the frequent hard-heartedness and cruelty found amongst those persons whose occupations engage them in destroying animal life, as well as from the uneasiness which others feel in beholding the butchery of animals.”
