But in spite of its fundamental importance, civil liberty in this sense does not guarantee public opinion in the modern world. For it always assumes, either that truth is spontaneous, or that the means of securing truth exist when there is no external interference. But when you are dealing with an invisible environment, the assumption is false. The truth about distant or complex matters is not self-evident, and the machinery for assembling information is technical and expensive. Yet political science, and especially democratic political science, has never freed itself from the original assumption of Aristotle's politics sufficiently to restate the premises, so that political thought might come to grips with the problem of how to make the invisible world visible to the citizens of a modern state.
So deep is the tradition, that until quite recently, for example, political science was taught in our colleges as if newspapers did not exist. I am not referring to schools of journalism, for they are trade schools, intended to prepare men and women for a career. I am referring to political science as expounded to future business men, lawyers, public officials, and citizens at large. In that science a study of the press and the sources of popular information found no place. It is a curious fact. To anyone not immersed in the routine interests of political science, it is almost inexplicable that no American student of government, no American sociologist, has ever written a book on news-gathering. There are occasional references to the press, and statements that it is not, or that it ought to be, "free" and "truthful." But I can find almost nothing else. And this disdain of the professionals finds its counterpart in public opinions. Universally it is admitted that the press is the chief means of contact with the unseen environment. And practically everywhere it is assumed that the press should do spontaneously for us what primitive democracy imagined each of us could do spontaneously for himself, that every day and twice a day it will present us with a true picture of all the outer world in which we are interested.
This insistent and ancient belief that truth is not earned, but inspired, revealed, supplied gratis, comes out very plainly in our economic prejudices as readers of newspapers. We expect the newspaper to serve us with truth however unprofitable the truth may be. For this difficult and often dangerous service, which we recognize as fundamental, we expected to pay until recently the smallest coin turned out by the mint. We have accustomed ourselves now to paying two and even three cents on weekdays, and on Sundays, for an illustrated encyclopedia and vaudeville entertainment attached, we have screwed ourselves up to paying a nickel or even a dime. Nobody thinks for a moment that he ought to pay for his newspaper. He expects the fountains of truth to bubble, but he enters into no contract, legal or moral, involving any risk, cost or trouble to himself. He will pay a nominal price when it suits him, will stop paying whenever it suits him, will turn to another paper when that suits him. Somebody has said quite aptly that the newspaper editor has to be re-elected every day.
