The Public and Its Problems

of the existence of a genuine and effective public. The use of science to regulate industry and trade has gone on steadily. The scientific revolution of the seventeenth century was the precursor of the industrial revolution of the eighteenth and nineteenth. In consequence, man has suffered the impact of an enormously enlarged control of physical energies without any corresponding ability to control himself and his own affairs. Knowledge divided against itself, a science to whose incompleteness is added an artificial split, has played its part in generating enslavement of men, women and children in factories in which they are animated machines to tend inanimate machines. It has maintained sordid slums, flurried and discontented careers, grinding poverty and luxurious wealth, brutal exploitation of nature and man in times of peace and high explosives and noxious gases in times of war. Man, a child in understanding of himself, has placed in his hands physical tools of incalculable power. He plays with them like a child, and whether they work harm or good is largely a matter of accident. The instrumentality becomes a master and works fatally as if possessed of a will of its own⁠—not because it has a will but because man has not.

The glorification of “pure” science under such conditions is a rationalization of an escape; it marks a construction of an asylum of refuge, a shirking of responsibility. The true purity of knowledge exists not when it is uncontaminated by contact with use and service. It is wholly a moral matter, an affair of honesty, impartiality and generous breadth of intent in search and communication. The adulteration of knowledge is due not to its use, but to vested bias and prejudice, to one-sidedness of outlook, to vanity, to conceit of possession and authority, to contempt or disregard of human concern in its use. Humanity is not, as was once thought, the end for which all things were formed; it is but a slight and feeble thing, perhaps an episodic one, in the vast stretch of the universe. But for man, man is the center of interest and the measure of importance. The magnifying of the physical realm at the cost of man is but an abdication and a flight. To make physical science a rival of human interests is bad enough, for it forms a diversion of energy which can ill be afforded. But the evil does not stop there. The ultimate harm is that the understanding by man of his own affairs and his ability to direct them are sapped at their root when knowledge of nature is disconnected from its human function.

It has been implied throughout that knowledge is communication as well as understanding. I well remember the saying of a man, uneducated from the standpoint of the schools, in speaking of certain matters: “Sometime they will be found out and not only found out, but they will be known.” The schools may suppose that a thing is known when it is found out. My old friend was aware that a thing is fully known only when it is published, shared, socially accessible. Record and communication are indispensable to knowledge. Knowledge cooped up in a private consciousness is a myth, and knowledge of social phenomena is peculiarly dependent upon dissemination, for only by distribution can such knowledge be either obtained or tested. A fact of community life which is not spread abroad so as to be a common possession is a contradiction in terms. Dissemination is something other than scattering at large. Seeds are sown, not by virtue of being thrown out at random, but by being so distributed as to take root and have a chance of growth. Communication of the results of social inquiry is the same thing as the formation of public opinion. This marks one of the first ideas framed in the growth of political democracy as it will be one of the last to be fulfilled. For public opinion is judgment which is formed and entertained by those who constitute the public and is about public affairs. Each of the two phases imposes for its realization conditions hard to meet.

Opinions and beliefs concerning the public presuppose effective and organized inquiry. Unless there are methods for detecting the energies which are at work and tracing them through an intricate network of interactions to their consequences, what passes as public opinion will be “opinion” in its derogatory sense rather than truly public, no matter how widespread the opinion is. The number who share error as to fact and who partake of a false belief measures power for harm. Opinion casually formed and formed under the direction of those who have something at stake in having a lie believed can be public opinion only in name. Calling it by this name, acceptance of the name as a kind of warrant, magnifies its capacity to lead action estray. The more who share it, the more injurious its influence. Public opinion, even if it happens to be correct, is intermittent when it is not the product of methods of investigation and reporting constantly at work. It appears only in crises. Hence its “rightness” concerns only an immediate emergency. Its lack of continuity makes it wrong from the standpoint of the course of events. It is as if a physician were able to deal for the moment with an emergency in disease but could not adapt his treatment of it to the underlying conditions which brought it about. He may then “cure” the disease⁠—that is, cause its present alarming symptoms to subside⁠—but he does not modify its causes; his treatment may even affect them for the worse. Only continuous inquiry, continuous in the sense of being connected as well as persistent, can provide the material of enduring opinion about public matters.

There is a sense in which “opinion” rather than knowledge, even under the most favorable circumstances, is the proper term to use⁠—namely, in the sense of judgment, estimate. For in its strict sense, knowledge can refer only to
