William G. Sumner, who coined the term ethnocentrism, is famously known as America's first sociology professor. He taught social sciences at the Yale University. It is wondrous, really, how this world is made up of so many different people belonging to different races or ethnicities.
Ethnocentrism is the belief that your culture is the standard and that what is normal in your culture should be the rule in every other culture. The concept of ethnocentrism is derived from the Enlightment critique of Western morals as universal and is rooted in the works of authors such as Montesquieu and Voltaire.
