Public Administration in the National Security System

When Newton first discovered the property of attraction, and settled its laws, he found it served very well to explain several of the most remarkable phenomena in nature ; but yet with reference to the general system of things, he could consider attraction but as an effect, whose cause at that time he did not attempt to trace. But when "he afterwards began to account for it by a subtile elastic æther, this great man (if in so great a man it be not impious to discover any thing like a blemish) seemed to have quitted his usual cautious manner of philosophising; since, perhaps, allowing all that has been advanced on this subject to be sufficiently proved, I think it leaves us with as many difficulties as it found us. That great chain of causes, which links one to another, even to the throne of God himself, can never be unravelled by any industry of ours. When we go but one step beyond the immediately sensible qualities of things, we go out of our depth.

The study of public administration must include its ecology. "Ecology," states the Webster Dictionary, "is the mutual relations, collectively, between organisms and their environment." J. W. Bews points out that "the word itself is derived from the Greek oikos a house or home, the same root word as occurs in economy and economics. Economics is a subject with which ecology has much in common, but ecology is much wider. It deals with all the inter-relationships of living organisms and their environment." Some social scientists have been returning to the use of the term, chiefly employed by the biologist and botanist, especially under the stimulus of studies of anthropologists, sociologists, and pioneers who defy easy classification, such as the late Sir Patrick Geddes in Britain.

Defined in broadest terms, public administration consists of all those operations having for their purpose the fulfillment or enforcement of public policy. This definition covers a multitude of particular operations in many fields — the delivery of a letter, the sale of public land, the negotiation of a treaty, the award of compensation to an injured workman, the quarantine of a sick child, the removal of litter from a park, manufacturing plutonium, and licensing the use of atomic energy. It includes military as well as civil affairs, much of the work of courts, and all the special fields of government activity— police, education, health, construction of public works, conservation, social security, and many others.
