On Letters is an epistolary essay, structured as thirteen wide-ranging and personal letters to the late conceptual artist On Kawara. Playing with language and its limits, the letters focus first on the artist’s five decade long body of “Date Paintings” and their relationship to typography. Yet from this starting point, the writing swerves to encompass topics such as the creative process, mindfulness, numbering systems, race, narrative structures, and more. On Letters is a unique glimpse into one artist’s inner dialogue and an exploration of how the solitary practice of artmaking can spark other transformations in the world.

"No one is better placed to reflect on On Kawara’s perfect marriage of typography and ontology than Prem Krishnamurthy. An intellectual triumph and a true labour of love." —Tom McCarthy
