“…Scientific anthropologists try to discover how primitive societies and other human groups manage; sociologists, how modern societies and their subsystems work; economists and socioeconomists, how the modern economic system operates; politologists and political sociologists, how the political system works; culturologists, what stimulates or inhibits the cultural system; and historians and archaeologists, how and why social systems have changed over time. This quest for understanding through hypothesizing mechanisms is what drove Thucydides, Aristotle, Ibn Khaldûn, Machiavelli, Hobbes, Locke, Holbach, Tocqueville, Marx, Durkheim, Simmel, Schumpeter, Keynes, Braudel, Merton, Coleman, Dahl, and Trigger, among others. The only recent novelty is that finally there is now more explicit talk of social mechanisms (see, e.g., Hedström and Swedberg 1998;Pickel 2001;Tilly 2001).…”
