The Love For All Living Creatures
The love for all living creatures is the most noble attribute of man.
About this quote
Charles Darwin wrote this in The Descent of Man (1871), in the chapter on the moral sense, where he argued that the capacity for sympathy and compassion toward other creatures was a natural outgrowth of human social instincts. Darwin's own compassion for animals was well documented; he was reportedly disturbed by witnessing animal suffering during his travels and in laboratory experiments.
