DonnywithanA:Well to say that something is universally preferable is to say that it is preferable that all people do it. To say that something is universally preferred is to say that all people prefer it. The latter is nonsensical; the former describes a moral theory of any content. I don't understand how either proves libertarianism as the one true doctrine. One thing I just stumbled upon in Gerald Sauer's 1982 essay, Imposed Risk Controversies: A Critical Analysis, was the statement, "Libertarian conceptions of rights are themselves shorthand notions for the respect owed to others" (8). I like that characterization a lot better!
(a) NO such things as "rights". "Right" is actually muddled shorthand itself, for the concept of negative-obligation. And, negative obligation, itself, is a shorthand for the logic of universal reciprocity: "Do NOT unto others, as you would NOT have them do unto you".
(b) Nobody "owes respect" to anyone else, as if there was some unchosen debt to be paild. You EARN respect, by your actions. Reason should be "respected" by an in-kind reciprocation of reason. Violence should be "respected" with an in-kind reciprocation of violence (or defensive action). Reciprocity is respect.
