A strong argument against modern ethics of natural rights is the skepticism these often elicit, even among libertarians. If one of these doctrines actually were unassailable, then it presumably would receive overwhelming support in the libertarian community, if not more widely.
A critical review of the normative
arguments and the empirical evidence for natural rights seems relevant,
therefore, and could lead to a more nuanced and less principled approach. The
common modern definition of “natural rights” is used in this context, namely
the universal right to self-ownership, homesteading, and private property.
