The freedom of expression is one of the most important rights after the right of life. But why the freedom of expression so necessary? Because we need it in order to undestand diversity and differing prospectives and so to resolve conflicts; moreover the freedom of expression is necessary in order to be able to determine which ideas are the closest to the truth. Competition between ideas is needed to bring out all the relevant facts and arguments on any issue so that the most rational explanations can win out.
Finally, we notice that in the countries where a person can’t say something without being influenced or criticized by someone else, where he can’t think and do something without another person imposes some restrictive rules, the freedom of expression doesn’t exist. So the principal objective of all consists to diffuse this right because it is needed for the progress of civilization. Without the freedom of expression we became all equal, but the world s beautiful because it is manifold.
