Ideal Theory: True and False

Abstract

In The Tyranny of the Ideal (2016), Gerald Gaus offers a critique of ideal theory, as practiced by political philosophers from Plato to the present day. This critique rests upon a formal model Gaus develops of a theory of the ideal. This model supposedly captures the essential features of any theory that both identifies an ideal society and uses that society to orient political activity. A theory must do the former or fail to count as an ideal theory; a theory must do the latter or prove useless. Gaus then employs this model to argue against ideal theory, using it as the foundation for an alternative model for how political philosophers should think about justice. Unfortunately, Gaus’ model of a theory of the ideal is badly flawed. Gaus fails to demonstrate the desirability of an ideal theory functioning in the manner his model suggests. Moreover, his model bears no correspondence to any existing contemporary theory of justice. In the end, Gaus’ model fails to provide any reason to believe there is any tyranny of the ideal to be overthrown.
