"Such definitions come too near to saying that economics is the science of things generally, of everything that men are for practical reasons interested in. Such a definition is useless and misleading"

“In Professor Pigou's study the argument that free enterprise lead to excessive investments in industry having relatively upward-sloping cost curves is developed with the aid of concrete example, the case of two roads; Suppose that between two points there are two highways, one of which is broad enough to accommodate without crowding all the traffic which may care to use it, but is poorly graded and surfaced; while the other is a much better road, but narrow and quite limited in capacity. If a large number of trucks operate between the two termini and are free to choose either of the two routes, they will tend to distribute themselves between the roads in such proportions that the cost per unit of transportation, or effective returns per unit of investment, will be the same for every truck on both routes. As more trucks use the narrower and better road, congestion develops, until at a certain point it becomes equally profitable to use the broader but poorer highway.”

“Economics and ethics naturally come into rather intimate relations with each other since both recognizedly deal with the problem of value.”

“Since economics deals with human beings, the problems of its scientific treatment involves fundamental problems of the relations between man and his world. From a rational or scientific point of view, all practically real problems are problems in economics. The problem of life is to utilize resources "economically," to make them go as far as possible in the production of desired results. The general theory of economics is therefore simply the rationale of life. - In so far as it has any rationale! The first question in regard to scientific economics is this question of how far life is rational, how far its problems reduce to the form of using given means to achieve given ends. Now this, we shall contend, is not very far; the scientific view of life is a limited and partial view; life is at bottom an exploration in the field of values, an attempt to discover values, rather than on the basis of knowledge of them to produce and enjoy them to the greatest possible extent. We strive to "know ourselves," to find out our real wants, more than to get what we want. This fact sets a first and most sweeping limitation to the conception of economics as a science.”

“is the only one who really deals with the problem of causes or approaches the material from that angle that can alone yield an answer to such questions, that is, the angle of comparative history in the broad sense.”

“In spite of all the foregoing, there is a science of economics, a true, and even exact, science, which reaches laws as universal as those of mathematics and mechanics. The greatest need for the development of economics as a growing body of thought and practice is an adequate appreciation of the meaning, and the limitations, of this body of accurate premises and rigorously established conclusions. It comes about in the same general way as all science, except perhaps in a higher degree, i.e., through abstraction. There are no laws regarding the content of economic behavior, but there are laws universally valid as to its form. There is an abstract rationale of all conduct which is rational at alt, and a rationale of all social relations arising through the organization of rational activity.”

“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.”
