Drawing on the views of influential sixth to fourteenth-century theorists and art historians and connoisseurs, the first part explains and discusses qiyun and its conceptual development from a notion mainly applied to figure painting to one that also plays an enduring role in the aesthetics of landscape painting. In the light of Kant’s account of genius, the second part examines a range of issues regarding the role of the mind in creating a painting replete with qiyun and the impossibility of teaching qiyun. Through this comparison with Kant, Hu demystifies the uniqueness of qiyun aesthetics and also illuminates some limitations in Kant’s aesthetics.
