Allow me to confess my guilt; I have not read the entire essay, only your extract and the first six pages. I may finish it, but no guarantees.
I found it to be clear but moderately dense. It is very worth reading especially the dependence of modern liberty upon a religious foundation.
If I have one complaint so far, it is that his definition of "liberalism" doesn't work well in America. At first, I thought he was exploring Jeffersonian liberalism as a contemporary, but no, it was written in 2002 (or translated in 2002 with help from the author, I forget which.)
In “Critique of Liberal Ideology,” Alain de Benoist uses the term “liberalism” in the broad Europe an sense of the term that applies not just to American liberalism but even more so to American libertarianism and mainstream conservatism, insofar as all three share a common history and common premises .—Transl.Instead of a translator's note that says de Benoist uses the term "Liberalism" to mean Liberalism, Conservatism, and European Liberalism, he should have insisted on a new term that doesn't include apparent opposites and a term "European Liberalism," with which many Americans are unfamiliar.
Get over that hump, and it's a big one, and it's pretty clear sailing.
Examples of my trouble?
On the one hand, liberalism is an economic doctrine that tends to make the model of the self- regulating market the paradigm of all social reality
On the other hand, liberalism is a doctrine based on an individualistic anthropology, i.e., it rests on a conception of man as a being who is not fundamentally social.
. . .insofar as it is based on individualism, liberalism tends to sever all social connections that go beyond the individual. As for the market’s optimal operation, it requires that nothing obstruct the free circulation of men and goods, i.e., borders must be treated as unreal, which tends to dissolve common structures and values. Of course this does not mean that liberals can never defend collective identities. But they do so only in contradiction to their principles.
I don't think these quotes define what most Americans think of as "Liberalism," but feel free to correct me.
