Human behavior is the joint product of (i) contingencies of survival responsible for natural selection, and (ii) contingencies of reinforcement responsible for the repertoires of individuals, including (iii) the special contingencies maintained by an evolved social environment. Selection by consequences is a causal mode found only in living things, or in machines made by living things. It was first recognized in natural selection: Reproduction, a first consequence, led to the evolution of cells, organs, and organisms reproducing themselves under increasingly diverse (...) conditions. The behavior functioned well, however, only under conditions similar to those under which it was selected.Reproduction under a wider range of consequences became possible with the evolution of processes through which organisms acquired behavior appropriate to novel environments. One of these, operant conditioning, is a second kind of selection by consequences: New responses could be strengthened by events which followed them. When the selecting consequences are the same, operant conditioning and natural selection work together redundantly. But because a species which quickly acquires behavior appropriate to an environment has less need for an innate repertoire, operant conditioning could replace as well as supplement the natural selection of behavior.Social behavior is within easy range of natural selection, because other members are one of the most stable features of the environment of a species. The human species presumably became more social when its vocal musculature came under operant control. Verbal behavior greatly increased the importance of a third kind of selection by consequences, the evolution of social environments or cultures. The effect on the group, and not the reinforcing consequences for individual members, is responsible for the evolution of culture. (shrink)

Abstract. The introduction of English as the medium of instruction for higher education in India in 1835 created a ferment in society and in the religious beliefs of educated Indians—Hindus, Muslims, and, later, Christians. There was a Hindu renaissance characterized by the emergence of reform movements led by charismatic figures who fastened upon aspects of Western thought, especially science, now available in English. The publication of Darwin's On the Origin of Species in 1859 was readily assimilated by educated Hindus, and (...) several reformers, notably Vivekananda and Aurobindo, incorporated evolution into their philosophies. Hindu scientists such as Jagadish Chandra Bose were also influenced by Darwinian evolution, as were a number of modern Hindu thinkers. The results of an investigation into the religious beliefs of young Indian scientists at four centers were also summarized. The view that “what goes around comes around” appears increasingly to be open to doubt. Many educated Indians, not only Hindus, are raising more probing questions that call for deeper dialogues between science and religion, especially about what each believes it means to be truly human.
