The difference between libertarian and conservatism:
Jim Kalb speaks on this important topic:
"Conservatism and libertarianism are both generally viewed as right-wing. Can you spell out the main differences between them from the conservative point of view? What, in your view, are libertarianism's shortcomings?
Kalb: They're both viewed as right-wing because centralized bureaucratic control is the main engine of social rationalization at present. From a theoretical standpoint ideological libertarianism is just another form of rationalism and not at all conservative. As a practical matter though it's mostly an ally of tradition because it opposes the main current enemy, the PC social-services state. The shortcoming of ideological libertarianism is that it says that a very few simple principles are enough for the whole of government and social life. Depending on circumstances that shortcoming can cause serious problems. In practice of course things get complex. People who call themselves libertarians sometimes have a strong streak of philosophical conservatism. They might find libertarian terms a better way to explain their case to the American people and even themselves. That kind of fusionist position can work to the extent the political disputes that matter don't involve government functions that conservatives want to keep and libertarians don't. "

I would put it a little differently. I view conservatives as holding first a value-laden vision of what America should look like, involving tradition, family, and a certain sternness and emphasis on just desserts. Libertarians also hold a value-laden vision, but their rhetoric involves a greater emphasis on "liberal neutrality" and competing lifestyles. I view the competing lifestyles vision as much of a particularist value as the conservative vision (while noting I am closer to a libertarian in this regard, but I do not give libertarianism an a priori elevation over conservatism on liberty grounds). Libertarians share the conservative emphasis on just deserts, hence the immense popularity of Ayn Rand in the libertarian movement. It is for this reason that alliances between libertarians and conservatives are often possible - they share a key value or presupposition. Modern liberals tend to emphasize beneficience instead of just deserts. My personal view is to share this value judgment with liberals (I am a determinist and usually find merit arguments unpersuasive), yet through positive arguments I get to something closer to a libertarian position. We also can (and should) use positive arguments to determine whether implementing the conservative value-laden vision, or the libertarian competing lifestyles vision, will do more for human welfare. In other words, we can make conservatism and libertarianism more compatible, and commensurable in the realm of positive argumentation, but only by dropping their upfront values into a position of secondary relevance.

That's a lot of big ideas in a medium that allows only for short posts, I do understand. I very much enjoyed Kalb's observations across the board, read the whole interview, with part three still to come, at www.2blowhards.com.
