Abstract: Klein and Clark (2010) initiated a debate about libertarian theory to which this paper hopes to add. Starting with the old libertarian principle of “direct liberty” (adherence to the non-aggression principle) Klein and Clark introduced two new concepts to complete it: “indirect liberty,” and also direct liberty plus indirect liberty, which sums to “overall liberty.” In my critique of this article of theirs (Block, 2011A), I congratulated them for their creativity, but rejected these innovations. In Klein and Clark (2012), these authors responded to my initial criticism. The present essay hopes to fruitfully continue the discussion of these new concepts of liberty.
