When you love someone you do not notice her or his imperfections, and this applies to self-love or narcissism too. The libertarians are narcissistic. They are in love with their own good looks, good mind, and good theories. That is why they fail to notice the imperfections in their attitude and work.
They want to make history, but they have no sense of history. They want to transform culture, but they have no sense of culture. They want to attain political power, but their understanding of the political situation is abysmal. They claim to stand for liberty, but most libertarian groups are cultist. They clamor for reform, but they don’t understand that the result of reform is often the opposite of what the reformers had in mind. They won’t accept that there are political and cultural problems for which there are no solutions.
The only area in which the work of some libertarians can be taken seriously is economic theory, but the world does not move by economics alone.
