What is the idea of self government is in the constitution what are these words?

The idea of self-government in the constitution is based on the principle of popular sovereignty, which means that political power ultimately resides with the people. This concept is enshrined in the preamble of the U.S. Constitution, which begins with the words "We the People."

The idea of self-government is further reflected throughout the document in the establishment of a system of government with three separate branches (executive, legislative, and judicial) that are designed to check and balance each other's power. This system is meant to ensure that no one branch of government becomes too powerful and that decisions are made in the best interest of the people.

Overall, the Constitution lays out the framework for a government that is designed to be of the people, by the people, and for the people. It emphasizes the importance of individual rights and freedoms and the ability of the people to govern themselves through a democratic process.
