Is the Declaration of Our Basic Freedoms in the Bill of Rights Necessary?

During the time the founder's of the U.S. Constitution decided to come up with a Bill of Rights, there were some opposing view points. Was it really necessary to include the five basic freedoms with the First Amendment? As it was to be assumed that the Constitution provides all citizen with the rights they deserved, why did the rights to free speech, press, assembly, religion and petition of the government deserve a specific statement? I believe that because the U.S. Constitution is so vague, it was necessary to express these individual rights. The five basic freedoms are important and should not be overlooked if the Constitution were to be misinterpreted. They are essential in any democracy as they grant power to the people so that the government cannot control them without their ability to voice their own opinion against it.
