How does the language of the preamble reflects the idea of the social contract?

The preamble opens with "We the People of the United States of America, in order to form a more perfect union". The use of the term "we" implies that more than one person, so a society coming together to put this Constitution together.

It then follows these rules to "establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity". Those rules establish the contract part.

The Preamble is the opening statement to the United States Constitution. The preamble explains the reasons why the Framers of the Constitution made the government a republic. By doing this, the founding fathers replaced the Articles of Confederation.

The Preamble along with the rest of the Constitution was written over a period of about 6 weeks. The Preamble helped explain why the Constitution was written. However, it is not the law.

The Preamble can be broken down into many important phrases. All of these phrases are very important for understanding the purpose of the United States Constitution.

We the people: This phrase means all the citizens of the United States of America. Even though the Constitution was written up by some of the most well-educated men of the new country, the rights given under the document were given to all American citizens.

In order to form a more perfect union: The previous government was based on the Articles of Confederation, which were very limited. When the Framers wrote this, they felt that they were making new government that would be a better way to govern the country.
