Final answer:
James Madison's quote emphasizes the need for government due to the imperfect nature of human beings.
Step-by-step explanation:
In this quote, James Madison is expressing the idea that if people were inherently perfect (like angels), there would be no need for a government because everyone would always do what is right and just.
However, since humans are flawed, a government is necessary to establish laws, enforce them, and provide a system of checks and balances to prevent abuses of power. Madison acknowledges that in order for a government to be successful, it must be designed to control both the governed and the government itself.
In conclusion, James Madison's quote highlights the need for government due to the imperfect nature of human beings.
