Answer:
Thomas Jefferson's phrase "Life, liberty, and the pursuit of happiness"
Explanation:
The concept of "Life, liberty" is expressed in one of the most famous works of John Locke: the Two Treatises of Government (1689). According to Locke, men are naturally free and equal, but with the purpose to interact in a healthy society, it was necessary that they transferred some of their rights to a government. Such government had to be elected by the people and changed by the people whenever they decided to, and had to ensure people's stability, conflicts resolutions, and people's right to life, freedom, and property.
The concept of "pursuit of happiness" is said to be taken out from one of the others Locke's work: An Essay Concerning Human Understanding (1689), where the philosopher expressed that "the highest perfection of intellectual nature lies in a careful and constant pursuit of true and solid happiness".
