'The importance of this outstanding work goes well beyond reshaping our understanding of Koryŏ. Indeed, Koryŏ’s way of understanding and living within the world as analyzed by Breuker would become an object of fear during the subsequent Chosŏn (1392-1910) dynasty. Those fears—and the way they came to be expressed—provide much additional evidence for Breuker’s thesis on Koryŏ’s pluralism. They also point to a profound historical irony. In the minds of the Chosŏn elite, Myoch’ŏng was synonymous with political disorder. Yet in a fundamental sense, the Chosŏn elite’s outlook had far more in common with Myoch’ŏng’s monism than with Kim Pusik’s pluralism. Among many other things, Breuker illuminates the origins of that remarkable contradiction.'Gregory Evon, University of New South Wales, The Review of Korean Studies 16:2 (2013)
