Aesthesis, the classical term for sensing and perceiving, is at the heart of innumerable problems that plague global society. The purpose of this article is to open a conversation on aesthesis. We survey the roots and relevance of aesthesis as a direct albeit contested relation and engagement with the world and with Others. From its pre-Socratic origins, aesthesis has been both a pragmatic, somatic concept, prompting a re-evaluation of the distinction between experience and abstraction. We trace its ongoing repression from (...) Plato through ‘western’ theories of formal Aesthetics. Drawing on a relational interpretation of Protagoras’ aesthesis, we argue that modern pragmatists and radical empiricists, as well as more contemporary critics of the ‘colonization’ of aesthesis (Mignolo and Vasquez) by formal Aesthetics recognize and develop the relational and ethical aspects of aesthesis. We consider the role of the body, affect, and of the intangible or virtual qualities of aesthesis. The ethics of obligations (Weil) in the polis (Arendt) shows how aesthesis informs politics despite its repression in favour of moral and legal norms. We argue this is relevant to contemporary crises such as xenophobia and ecocidal climate warming. (shrink)
