 The concept religion understood as a social genus was increasingly put to use by to European Christians as they sought to categorize the variety of cultures they encountered as their empires moved into the Americas, South Asia, East Asia, Africa, and Oceania. In this context, fed by reports from missionaries and colonial administrators, the extension of the generic concept was expanded. The most influential example is that of anthropologist Edward Burnett Tylor (1832–1917) who had a scholarly interest in pre-Columbian Mexico. Like Herbert, Tylor sought to identify the common denominator of all religions, what Tylor called a “minimal definition” of religion, and he proposed that the key characteristic was “belief in spiritual beings” (1871 [1970: 8]). This generic definition included the forms of life predicated on belief in a supreme deity that Herbert had classified as religion. But it could also now include—without Herbert’s procrustean assumption that these practices were really directed to one supreme being—the practices used by Hindus, ancient Athenians, and the Navajo to connect to the gods they revere, the practices used by Mahayana Buddhists to connect to Bodhisattvas, and the practices used by Malagasy people to connect to the cult of the dead. The use of a unifying concept for such diverse practices is deliberate on Tylor’s part as he sought to undermine assumptions that human cultures poorly understood in Christian Europe—especially those despised ones, “painted black on the missionary maps” (1871 [1970: 4])—were not on the very same spectrum as the religion of his readers. This opposition to dividing European and non-European cultures into separate categories underlies Tylor’s insistence that all human beings are equivalent in terms of their intelligence. He argued that so-called “primitive” peoples generate their religious ideas when they wrestle with the same questions that all people do, such as the biological question of what explains life, and they do so with the same cognitive capacities. They may lack microscopes or telescopes, but Tylor claims that they seek to answer these questions in ways that are “rational”, “consistent”, and “logical”. Tylor repeatedly calls the Americans, Africans, and Asians he studies “thinking men” and “philosophers”. Tylor was conscious that the definition he proposed was part of a shift: though it was still common to describe some people as so primitive that they had no religion, Tylor complains that those who speak this way are guilty of “the use of wide words in narrow senses” because they are only willing to describe as religion practices that resemble their own expectations (1871 [1970: 3–4]).
