In simple terms, Milton rejects the need for censorship of published information and texts. This indubitably irritates the people in charge, which during this period would be the Parliament and the Roman Catholic Church. Milton believes that censorship hinders or stops the people from exploring their trust for knowledge and truth.
Censorship is truly unnecessary. There will always be people in the world who will find a way to bypass the restrictions of the government. Although America is said to have free speech (1st amendment), the citizens are always being watched. Certain ideas, phrases, books, or information is flagged as dangerous or ‘need to know’ only by the government.
Today, censorship plays a huge role in politics and news coverage. The amount of ignorance that the American people display is partly because of the information being provided by the government (of course, there is fault in the citizens also). Could Milton be right about the pursuit of knowledge and the affects that censorship plays upon it?
To me at least, he seemed to be on to something.
