Judith Shklar once remarked that the mere presence of ideology is not objectionable but that pretended immunity to ideology is. I scrutinize this suggestion and Shklar’s subsequent view that social theorists should acknowledge that their ideological impulses influence both their methods of study and the questions they pursue. I begin by focusing on the different ways that Shklar characterizes ideology before turning to her critique of legalism. I then chart various ways that Shklar’s call for ideologically self-aware political theorizing feeds into her later work. I conclude by examining what ideological self-consciousness implies for our understanding of the purpose and limits of political theory.
