Buckley: Oh, absolutely; very much so. The libertarian hubris--Ayn Rand took it to its extreme--really suggests the only thing that matters is your own satisfaction. Now, they will subtly acknowledge that your satisfaction might be affected by philanthropic enterprises, but that does strike me as cynical. What they are saying is that what matters is not that you have helped the poor; what matters is that you feel better, and if you feel better, then you are simply exercising your rights under a libertarian order. What they refuse to accept, what is denounced under Randism, is altruism. It is the notion that you might help the poor because you feel it is the right thing to do.
I am a presumptive libertarian, which is to say I believe a very hard case has to be made before the intervention of the state, but the presumption is rebuttable. In many ways, a libertarian would say it's not rebuttable, it's absolute.
Under all those words, the idea that Libertarianism is about ME, as a person, and that I should feel good, rather than we doing something because it the right thing, though the government may be doing it.
