Reading edition
“The animal species in which individual struggle has been reduced to its narrowest limits, and the practice of mutual aid has attained the greatest development, are invariably the most numerous, the most prosperous, and the most open to further progress” (Kropotkin, Mutual Aid (1909), p. 293). See also Bixby, The Crisis in Morals (1891), p. 235.
