Religion, various grades of spirit and nature worship, corresponding to the various cultural grades; a crude form of shamanism prevalent amongst most of the North American aborigines, polytheism with sacrifice and priestcraft amongst the cultured peoples (Aztecs, Mayas, etc.); the monotheistic concept nowhere clearly evolved; belief in a natural after-life very prevalent, if not universal.

Culture, highly diversified, ranging from the lowest stages of savagery through various degrees of barbarism to the advanced social state of the more or less civilised Mayas, Aztecs, Chibchas, Yungas, Quichuas, and Aymaras; amongst these pottery, weaving, metal-work, agriculture, and especially architecture fairly well developed; letters less so, although the Maya script seems to have reached the true phonetic state; navigation and science rudimentary or absent; savagery generally far more prevalent and intense in South than in North America, but the tribal state almost everywhere persistent.
