This essay explores the theoretical implications of Freud's notion of `the narcissism of minor differences' - the idea that it is precisely the minor differences between people who are otherwise alike that form the basis of feelings of strangeness and hostility between them. A comparative survey shows that minor differences underlie a wide range of conflicts: from relatively benign forms of campanilismo to bloody civil wars. Freud's tentative statements link up with the insights of Simmel, Durkheim, Lévi-Strauss, Dumont, Elias, and (...) Girard. Especially helpful is what Bourdieu writes in Distinction: social identity lies in difference, and difference is asserted against what is closest, which represents the greatest threat. An outline of a general theory of power and violence should include consideration of the narcissism of minor differences, also because its counterpart - hierarchy and great differences - makes for relative stability and peace.
