ethnocentric (adj.)youdaoicibaDictYouDict[ethnocentric 词源字典]
"believing that one's own nation is the center of civilization," 1891, from ethno- + -centric; a technical term in social sciences until it began to be more widely used in the second half of the 20th century. Related: Ethnocentricity; ethnocentrism (1902).
Dr. Gumplowicz, professor of sociology at the University of Gratz, says that there are illusions which have been most baneful in the wider life of the world. He mentions two of them which, with real German facility for coining new names, he calls "acrochronism" and "ethnocentrism." ["Address of Professor J.C. Bracq," in "The Eighth Lake Mohonk Arbitration Conference," May 28, 1902; he adds, "Acrochronism is the illusion which leads us to think that what we are doing is the culminating point of some great process."]

folkways (n.)youdaoicibaDictYouDict
coined 1906 in a book of the same name by U.S. sociologist William Graham Sumner (1840-1910); see folk (n.) + way (n.).
Folkways are habits of the individual and customs of the society which arise from efforts to satisfy needs. ... Then they become regulative for succeeding generations and take on the character of a social force. [Sumner, "Folkways"]
Sumner also often is credited with ethnocentrism, which is found in the same book but is older.
