What can urban policies and planning really learn from John Rawls? A multi-strata view of institutional action and a canvas conception of the just city

One of the most influential theories of justice in planning theory and practice has been, without doubt, that of John Rawls. The very idea of the just city is indebted to Rawls’s view. However, the way in which Rawlsian theory of justice has been imported into planning often seems debatable. This article aims to discuss this aspect critically. The objective is not merely to discuss certain planning approaches inspired by Rawls; it is also to investigate, in more general terms, what meaning and role (any theory of) justice could and should have for planning and urban policies. In revisiting John Rawls’s view, the article is structured around two points: first, a critical discussion on how Rawls’s theory of justice has been generally applied to urban policies and planning; second, an exploration of an alternative way to interpret and apply certain Rawlsian insights (often undervalued) in this field. The article is not intended to defend and recommend Rawls’s normative theory as a whole (i.e. in its entirety), but to evidence certain Rawlsian contributions of a general nature that are particularly important. Nor is it the aim of this article to contribute directly to the development of a specific substantive idea of the just city; instead, it is to highlight fundamental methodological and analytical caveats that are crucial in this regard. Rather than a “theory of the just city”, this article develops a “meta-theory of the just city”: that is, an approach specifying precautions and conditions for any coherent and convincing just city theory.
