Frank H. Knight's criticism of Henry George

The ferocity of Knight's comments on Henry George may come as a surprise to those who are not familiar with his criticisms of other economists and philosophers. But, in fact, his criticisms of George are not due to specifically Knightian insights on George's approach, but rather reflect the different philosophical framework from which neoclassical economists like Knight think. At the core of Knight's disagreements with George is his neoclassical theory of rent, as the Georgist critics of Knight understand. The article reviews the philosophical, economic, and ethical ideas that underlay Knight's neoclassicism, and hence inform his criticism of George.
