I disagree.
Liberalism is is nothing but the ideology of the retreat of post-Reformation Western Civilization. Its function is to provide an ideological structure to comfort those who have lost their faith as no longer wish to pursue the Christian civilizing goals of reahing a more advanced stage of cultural and moral and political development started by our forefathers. When we get to a point where our existence is threatened, and the decisive moment to advance instead of retreat comes, deprived of its primary function, this liberalism, this illogical and incoherent philosophy will fall away. There are signs that liberalism has already started to crack and fade.
Well put.
But can we be sure what ideas will form the vanguard of the advance?
