The passage presents a theory of natural rights: certain rights belong to people by virtue of their humanity rather than being granted by government. It identifies equality, life, liberty and the pursuit of happiness as fundamental principles. The claim that these truths are “self-evident” places them at the starting point of the document’s political argument rather than treating them as conclusions requiring proof.

The wider passage connects these rights to the purpose and legitimacy of government. Governments are described as being established to protect rights and as deriving their authority from the consent of the governed. It then argues that people may alter or abolish a government that persistently fails in this purpose. In the Declaration of Independence, these principles provide the philosophical basis for the American colonies’ case for separating from Britain, linking individual rights with popular sovereignty and political self-government.
