Students of administration, writes J. M. Gaus, have become "more uncertain in recent years as to the ends, aims and methods which they should advocate/' It is difficult to view in their entirety and in perspective the writings on public administration that now pour from the presses. But this is hardly necessary to confirm the truth of Gaus' statement.

Historically, "public administration" has grown in large part out of the wider field of inquiry, "political science." The history of American political science during the past fifty years is a story much too lengthy to be told here, but some important general characteristics and tendencies it has communicated to or shared with public administration must be noted.

The Gospel of Efficiency. Every era, as Carl Becker has reminded us in his Heavenly City of the Eighteenth Century Philosophers, has a few words that epitomize its world-view and that are fixed points by which all else can be measured. In the Middle Ages they were such words as faith, grace, and God; in the eighteenth century they were such words as reason, nature, and rights ; during the past fifty years in America they have been such words as cause, reaction, scientific, expert, progress and efficient. Efficiency is a natural ideal for a relatively immature and extrovert culture, but presumably its high development and wide acceptance are due to the fact that ours has been, par excellence, a machine civilization. At any event, efficiency grew to be a national catchword in the Progressive era as mechanization became the rule in American life, and it frequently appears in the literature of the period entangled in mechanical metaphor.
