Abstract
In this essay, I will outline a novel strategy for using constitutivist ideas from Kantian metaethics to critique social practices and institutions. In doing so, I do not mean to defend this model of critique as the only viable form of social and political critique, even within a Kantian framework – nor, indeed, as always the most appropriate. But I hope to show that it provides us with a form of critique that allows us to (i) develop a robust critique of many social practices (ii) on both epistemic and practical grounds, while nonetheless (iii) beginning from a perspective that is, in some sense, internal – or better, immanent – to the practice in question. Thus, if we are looking for a form of social critique that is neither purely epistemic nor merely external – which, in other words, allows us to critique social practices on something like their own terms as practically irrational – this method should be attractive for philosophers with Kantian (or post-Kantian) sympathies. At the heart of this conception of critique lies in the idea that social practices may be thought of as attempts at (some form of) collective practical understanding. As I will explain more below, this way of thinking about the rationality of social practices may be seen as the product of applying a general (post-Kantian) model of rationality, which I have developed elsewhere, to the rationality of social collectives or practices.
