The correct answer is the Declaration of Independence
Enlightenment philosopher John Locke developed a theory of natural rights in which every free person had the rights of life, liberty, and property and that a citizen entered into government to have government help protect those rights at the expense of some freedoms.
Thomas Jefferson was heavily influenced by Locke and developed the concept of natural rights and the social contract further writing in the Declaration of Independence that every citizen had the right to life, liberty, and the pursuit of happiness.
He means that whatever we do is for mankind. All the work is for the development of the humans.
