Isaiah Berlin's "Two Concepts of Liberty"
https://archive.org/details/Two_Concepts_Of_Liberty_Isaiah_Berlin_1958.pdf/
he distinguishes negative liberty, freedom from, vs positive liberty, freedom to, and discusses their domains.
examples:
negative liberty: right to be free from interference when associating voluntarily with others
positive liberty: right to affordable housing
a very useful framing for many common disputes
