Answer:
The phrase "life, liberty, and pursuit of happiness," was an idea first considered by Locke in his Two Treatises on Government.
Locke also wrote that all individuals are equal in the sense that they are born with certain "inalienable" natural rights. Those are rights that are God-given and can never be taken or even given away. Among these fundamental natural rights, Locke said, are "life, liberty, and property."
