Ágnes Heller goes back to antiquity to show under what circumstances prejudices can arise. She questions the social and psychological prerequisites and analyzes the fundamental prejudices of modernity: racial, ethnic, and religious prejudices, class prejudices, prejudices against women, and sexual prejudices. From Socrates to Shakespeare, from Leibniz through Weber to Foucault and Luhmann, the Grande Dame of philosophy reveals to us what she has personally experienced and continues to experience in the 20th and 21st centuries: a whole cosmos of prejudices.
