“The new profession of public relations has grown up because of the increasing complexity of modern life and the consequent necessity for making the actions of one part of the public understandable to other sectors of the public. It is due, too, to the increasing dependence of organized power of all sorts upon public opinion. Governments, whether they are monarchical, constitutional, democratic or communist, depend upon acquiescent public opinion for the success of their efforts and, in fact, government is government only by virtue of public acquiescence. Industries, public utilities, educational movements, indeed all groups representing any concept or product, whether they are majority or minority ideas, succeed only because of approving public opinion. Public opinion is the unacknowledged partner in all broad efforts.
The public relations counsel, then, is the agent who, working with modern media of communications and the group formations of society, brings an idea to the consciousness of the public.”

Context: You often hear people speaking as if life was like striving upward toward a mountain peak. That is not so. Life is as if you were traveling a ridge crest. You have the gulf of inefficiency on one side and the gulf of wickedness on the other, and it helps not to have avoided one gulf if you fall into the other. It shall profit us nothing if our people are decent and ineffective. It shall profit us nothing if they are efficient and wicked. In every walk of life, in business, politics; if the need comes, in war; in literature, science, art, in everything, what we need is a sufficient number of men who can work well and who will work with a high ideal. The work can be done in a thousand different ways. Our public life depends primarily not upon the men who occupy public positions for the moment, because they are but an infinitesimal fraction of the whole. Our public life depends upon men who take an active interest in that public life; who are bound to see public affairs honestly and competently managed; but who have the good sense to know what honesty and competency actually mean. And any such man, if he is both sane and high-minded, can be a greater help and strength to any one in public life than you can easily imagine without having had yourselves the experience. It is an immense strength to a public man to know a certain number of people to whom he can appeal for advice and for backing; whose character is so high that baseness would shrink ashamed before them; and who have such good sense that any decent public servant is entirely willing to lay before them every detail of his actions, asking only that they know the facts before they pass final judgment.

Context: No policy that does not rest upon some philosophical public opinion can be permanently maintained. And hence, there are but two policies in regard to Slavery that can be at all maintained. The first, based on the property view that Slavery is right, conforms to that idea throughout, and demands that we shall do everything for it that we ought to do if it were right. We must sweep away all opposition, for opposition to the right is wrong; we must agree that Slavery is right, and we must adopt the idea that property has persuaded the owner to believe — that Slavery is morally right and socially elevating. This gives a philosophical basis for a permanent policy of encouragement. The other policy is one that squares with the idea that Slavery is wrong, and it consists in doing everything that we ought to do if it is wrong. [... ] I don't mean that we ought to attack it where it exists. To me it seems that if we were to form a government anew, in view of the actual presence of Slavery we should find it necessary to frame just such a government as our fathers did; giving to the slaveholder the entire control where the system was established, while we possessed the power to restrain it from going outside those limits. From the necessities of the case we should be compelled to form just such a government as our blessed fathers gave us; and, surely, if they have so made it, that adds another reason why we should let Slavery alone where it exists.
