This document discusses different types of rights and theories related to them. It defines rights as claims that one is entitled to something. There are several dichotomies of rights discussed, including: natural vs. societal rights; moral vs. legal rights; and positive vs. negative rights. Natural rights are those we have for being human, like life, while societal rights depend on membership in a society. Moral rights are claims that ought to be respected, while legal rights are those that can be respected under the law. Positive rights require others to provide something, like healthcare, while negative rights prevent interference, like the right to not be beaten. For every right, someone has a corresponding duty to ensure that right.
