Abstract
This paper seeks to discover if urban planning has any 'internal values' which might help guide its practitioners and provide standards with which to judge their works, thereby providing for some disciplinary autonomy. After arguing that such values can best be discovered through an examination of the history of utopian urban planning, I examine one period in that history, the early Renaissance and, in particular, the work of Leon Battista Alberti. Against Susan Lang's thesis that Alberti's work was guided by the fundamental value of beauty, I argue that Alberti was centrally concerned to design cities that would help their citizens develop civic virtue. Against Françoise Choay's thesis that Alberti was not a utopian, I argue that Alberti was a procedural utopian interested in advancing certain political goals. This analysis suggests that urban planning has an internal value structure which includes some specific political values.
