In this article, I sketch out and examine the aesthetic basis of an implicit ontological model of community, grounded on dialogical practice, which appears in Grant Kester’s proposal for a dialogical theory of socially engaged contemporary art. I address two distinct but related aspects of Kester’s view on understanding as a constitutive part of dialogical aesthetic experience. First, I endeavour to show that the post-foundational framework of a ‘procedural knowledge’ which he uses to support his theory of aesthetic communication requires (...) a stronger intersubjective ground to ensure the actual empathic understanding of the other dialogical partner. In this respect, I claim that he could be using the Kantian notion of sensus communis in a constitutive rather than in a regulative manner, thus grounding empathy on an ante-predicative level of experiencing alterity. This unorthodox usage of the Kantian aesthetic postulate points towards a particular understanding of sensus communis as the universal communicability of human finitude, which I eventually argue for on the lines of Jean-Luc Nancy’s thinking.
