First, we might clear a common misunderstanding. A critique is not a project of finding fault, but an examination of the assumptions of a field of knowledge. Its purpose is to understand and suggest alternatives to the categories of knowledge that we use. Michel Foucault, who often worked in a spirit of critique, put it this way:

"A critique does not consist in saying things aren’t good the way they are. It consists in seeing on what type of assumptions, of familiar notions, of established, unexamined ways of thinking the accepted practices are based. (Foucault 2000c: 456)"
