For various reasons this shadowy caste is largely made up of men who have official stamps upon their learning--that is, of professors, of doctors of philosophy; outside of academic circles it tends to shade off very rapidly into a half-world of isolated anarchists. One of those reasons is plain enough: the old democratic veneration for mere schooling, inherited from the Puritans of New England, is still in being, and the mob, always eager for short cuts in thinking, is disposed to accept a schoolmaster without looking beyond his degree. Another reason lies in the fact that the higher education is still rather a novelty in the country, and there have yet to be developed any devices for utilizing learned men in any trade save teaching. Yet other reasons will suggest themselves. Whatever the ramification of causes, the fact is plain that the pedagogues have almost a monopoly of what passes for the higher thinking in the land. Not only do they reign unchallenged in their own chaste grove; they also penetrate to all other fields of ratiocination, to the almost complete exclusion of unshrived rivals. They dominate the weeklies of opinion; they are to the fore in every review; they write nine-tenths of the serious books of the country; they begin to invade the newspapers; they instruct and exhort the yokelry from the stump; they have even begun to penetrate into the government. One cannot turn in the United States without encountering a professor. There is one on every municipal commission. There is one in every bureau of the federal government. There is one at the head of every intellectual movement. There is one to explain every new mystery. Professors appraise all works of art, whether graphic, tonal or literary. Professors supply the brain power for agriculture, diplomacy, the control of dependencies and the distribution of commodities. A professor was until lately sovereign of the country, and pope of the state church.
