Walter Lippmann's Essay 'The Indispensable Opposition'

In the article "The Indispensable Opposition" the author, Walter Lippmann acknowledges that the right of freedom of speech is expressed inadequately and full of accidental one-way ideas. He believes to find the best solution, you need to listen to other opposing views.
Lippmann says that freedom of opinion is a "luxury", when people can only tolerate the opposing view they are not understanding the meaning of freedom of speech (1). He states that people should fight for other people to have the right to speak freely, but instead they ignore and don't listen to opposing views, which in return doesn’t make them gain any knowledge (1). He believes that "… to understand why freedom is necessary in a civilized society, we must begin by realizing

that, because freedom of discussion improves our own opinions, the liberties of other men are our own vital necessity" (2).
Lippmann observes that the base of freedom of speech is to find the truth, that there is no way we could possibly value our freedom of liberty if we continue to "tolerate" opposing views (3). In other countries without freedom, a totalitarian state, it is full of one-way broadcasting of one dictator's ideas (3). Lippmann adds that is a dictator was smart enough, they would use outside sources to report information back to him, so it would either strengthen his view or give feedback to what should be fixed (3). In a totalitarian state the opposition of a agreement is disappearing because it is controlled by men who have the same opinions and think alike (3).
Lippman declares that "the right to talk may be the beginning of freedom, the necessity of listening is what makes the right more important" (4). If everyone were to talk and no one listened, then there is not a point in speaking your opinion. The freedom of speech's purpose is when a viewpoint is expressed and then can be debated about and the audience able to confront the viewpoint with their own opposing view (4). When this occurs, the freedom should be held with pride because "… when men may voice their opinions because they must examine their opinions" (6).
Lippman concludes, that your supporters will always be there to push you but, your opponents will challenge you and better your views better than your friends ever could (7).
