Should nonideal theory rely on ideal theory? Lessons from the Frankfurt School

Abstract

While ideal theory tells us “what a perfectly just society would be like” (Rawls, 1971, p. 8), our current social world is far from perfectly just, and we clearly want to know how to orient ourselves and act in these less than perfectly just, or unjust, circumstances. This is why many political philosophers¹ today agree that what is needed is nonideal theory. There is, however, disagreement on one key issue. While some—most notably Charles W. Mills and Amartya Sen—have argued that nonideal theory does not need to build on ideal theory and should do without it, others have pointed out ways in which ideal theory may still be necessary for doing nonideal theory, and that ideal theory should not be dismissed so easily for the project of nonideal theory. The central question, then, is whether nonideal theory should rely on ideal theory.

In what follows, I would like to take up this question and propose an answer to it. I will do so by considering a more specific question. Taking the Frankfurt School as my point of departure, I would like to examine whether nonideal theory, when guided by ideal theory, can help members of the social world to understand injustices and thus contribute to their self-reflection. Advocates of nonideal theory should be concerned about the ability of nonideal theory to contribute to self-reflection, because whether it can successfully inform collective action to overcome injustice depends on its ability to contribute to self-reflection. In other words, what is at stake is nothing less than the practical relevance of political philosophy. As I will argue, however, reliance on ideal theory renders the ability of nonideal theory to contribute to self-reflection uncertain and therefore a matter of sheer luck. As a result, the ability of nonideal theory to successfully guide action is in constant doubt. I will therefore conclude by suggesting that if political philosophy wants to be practically relevant, nonideal theory should not rely on ideal theory.

My argument will involve four steps. First, I will explain my understanding of ideal and nonideal theory (Section 1), before addressing the debate about the role of ideal theory for nonideal theory (Section 2). I will then turn to the Frankfurt School and outline its basic approach to injustice and social problems in general (Section 3). Finally, I will examine what lessons advocates of nonideal theory can learn from the Frankfurt School, which is where the main action of this paper takes place (Section 4). I will conclude with a summary of the argument.
