The Ethics of Competition is a book of Frank H. Knight's writings on a common theme: the problem of social control and its various implications. Knight believed in free economic institutions but was also aware that the competitive economic system could be improved. One of the central figures of neoclassical economics in the twentieth century, Knight pursued a lifelong campaign against irrationalities of nationalism, religious fanaticism, and group conflict, while conceding that these were fundamental orientations of human action that might yet frustrate his own work as an economist. While Knight vigorously defended human freedom and the liberal order, he also was sufficiently moved by the shortcomings of liberalism as to condemn it as rife with abuse.
