Which idea is central to John Locke two treaties of government?

The central idea of john Locke's "Two Treatises of Government" is the concept of natural rights, which asserts that individuals possess inherent rights to life, liberty, and property. Locke argues that governments are formed through a social contract to protect these rights, and if a government fails to do so, the people have the right to overthrow it. He emphasizes the importance of consent and the belief that political authority is derived from the governed, laying the groundwork for modern democratic thought.
