 Buddhists do not distinguish between human beings as possessing a soul and other animals as soulless. As we are all part of the cycle of rebirth, we have all been in previous lives various other beings, including birds, insects, and fish. The problem of the specificity of the human soul does not even arise because of the no-self doctrine. Nevertheless, as Justin Ritzinger (2013) points out, Chinese Buddhists in the 1920s and 1930s who were confronted with early evolutionary theory did not accept Darwin’s theory wholesale. In their view, the central element of Darwinism—the struggle for existence—was incompatible with Buddhism, with its emphasis on compassion with other creatures. They rejected social Darwinism (which sought to engineer societies along Darwinian principles) because it was incompatible with Buddhist ethics and metaphysics. Struggling to survive and to propagate was clinging onto worldly things. Taixu (1890–1947), a Chinese Reformer and Buddhist modernist, instead chose to appropriate Pyotr Kropotkin’s evolutionary views, specifically on mutual aid and altruism. The Russian anarchist  argued that cooperation was central to evolutionary change, a view that is currently also more mainstream. However, Kropotkin’s view did not go far enough in Taixu’s opinion because mutual aid still requires a self. Only when one recognizes the no-self doctrine could one dedicate oneself entirely to helping others, as bodhisattvas do (Ritzinger 2013).
