Final answer:
John Locke's Two Treatises of Government proposed separation of powers within a government framework that protects life, liberty, and property, forming a social contract that influenced the U.S. Constitution.
Step-by-step explanation:
In John Locke's Two Treatises of Government, he proposed a form of government that is for the benefit of the people and can be changed if it fails to serve them. This is contrary to the concept of the Divine Right of Kings, which held that monarchs derive their right to rule directly from the will of God and are accountable only to God. Locke's vision includes the idea that government should protect life, liberty, and property and that there should be multiple branches of government to ensure checks and balances. This framework influenced the founding of the United States and its Constitution, reflecting the concept of a social contract between the governed and the government. Therefore, the visionary idea that Locke proposed in his Treatises can mostly be linked to the concept of separation of powers.
