Hey!!
In the 2nd paragraph of the Declaration of Independence.
“We hold these truths to be self evident that all men are created equal, that they are endowed with certain unalienable rights, that amount these are life, LIBERTY, and the pursuit of happiness.”
Thomas Jefferson, who wrote the declaration, greatly admired John Locke.
Locke’s list of natural rights (in which no one can take away) includes the right to property which in his definition, includes Liberty(freedom).
Hope this helps :)
