.. Having never been a coherent philosophy of government, conservatism exists as an amalgam of reactionary concepts loosely tied together by historical accident. The only apparent unifying theme among ideas as unrelated as opposition to gay marriage and aggressive foreign interventionism is a fear of the unfamiliar. This reactionary nature is leading conservatives down a path to irrelevance in an age of improved communication, access to information, and cultural understanding.
Murray Rothbard pointed out that conservatism, lacking a coherent ideology, offers only a practical defense of the existing status quo, reacting to progressivism in defense of "tradition." But when progressive reforms endure and become part of that tradition, conservatives lose their intellectual ammunition and end up accepting the change, for better or worse.
Through the decades, conservatives have been overwhelmingly impotent at preserving their ever-shifting vision of tradition. They have over the last century lost their battles against Wilsonian progressivism, the New Deal, the Great Society, racial integration, abortion, drug abuse, and secularization, and they are now losing their fights against gay rights and so-called illegal immigration. The fact that they have lost so reliably, despite their persistent numerical superiority, is a testament to the holes in their philosophy. Along the way, they've adopted virtually every bureaucratic idea pioneered by progressives, increasing government spending while wasting energy and billions of dollars fighting losing cultural battles.
.. Libertarians are skeptical of power in an age of skepticism, embrace science in an era of rapid scientific improvement, reject banal expressions of nationalism in an increasingly-globalized world, and remain dedicated to individualism, not for tradition's sake, but to advance mankind's virtually limitless potential.
Libertarianism is the true yin to progressivism's yang: a platform consistently emphasizing individual rights and self-determination can more effectively combat the global march toward collectivism and consolidation without conservatism's archaic cultural baggage.
