“The word science of administration has been used. There are many who object to the term. Now if by science is meant a conceptual scheme of things in which every particularity coveted may be assigned a mathematical value, then administration is not a science. In this sense only astro-physics may be called a science and it is well to remember that mechanical laws of the heavens tell us nothing about the color and composition of the stars and as yet cannot account for some of the disturbances and explosions which seem accidental. If, on the other hand, we may rightly use the term science in connection with a body of exact knowledge derived from experience and observation, and a body of rules or axioms which experience has demonstrated to be applicable in concrete practice, and to work out in practice approximately as forecast, then we may, if we please, appropriately and for convenience, speak of a science of administration. Once, when the great French mathematician, Poincaré, was asked whether Euclidean geometry is true, he replied that the question had no sense but that Euclidean geometry is and still remains the most convenient. The Oxford English Dictionary tells us that a science is, among other things, a particular branch of knowledge or study; a recognized department of learning.”

“If I were compelled to state in a single sentence the most significant contribution of our movement to modern civilization, I should say that it is the application of the idea of continuous and experimental research, found so effective in economic enterprise, to the business of public administration intimately and in a deep-thrusting sense, a contribution to the processes by which modern mankind is striving with all its resources to emancipate itself from the tyranny of rules of thumb and the blind regimen of nature, becoming conscious of its destiny as an all conquering power.”

“If this statement by Judge Cooley is true, and the authority for it is unimpeachable, then the theory that the Constitution is a written document is a legal fiction. The idea that it can be understood by a study of its language and the history of its past development is equally mythical. It is what the Government and the people who count in public affairs recognize and respect as such, what they think it is. More than this. It is not merely what it has been, or what it is today. It is always becoming something else and those who criticize it and the acts done under it, as well as those who praise, help to make it what it will be tomorrow.”

“In other words, there are in administration things analogous to, if not identical with, the mechanical tracts or deterministic sequence, of physics. If, for example, it is decided by government to accomplish the purpose of providing compensation at given rates for men and women employed in industry who sustain injuries in connection with their occupations, the administrator can, like the engineer, estimate in advance the probable cost of such a design, indicate the types of officers and employees necessary to administer the design, and the administrative procedures appropriate to the whole process from beginning to end. And, as in the case of the hydro-electric engineer, the administrator, later sees the results of his operations and can compare them with his advance estimates. There are more variables and incalculables in human affairs than in hydroelectric affairs, but even so administration achieves pre-determined results with an approximation which is often amazing for its exactness. If administrative designs and estimates were not realized in practice with a high degree of exactness, both industry and government would collapse.”

“And if the experience of natural science is any guide, then as the science of administration advances, we may reasonably expect it to take on an increasingly deterministic character. As research, scientific societies, and the exchanges of knowledge and hypotheses by natural scientists have advanced the exactness of knowledge in the domain of natural science, so we may expect research, administrative societies, and the exchanges among administrators to advance the exactness of knowledge in the domain of administration.”
