Liberalism… is often successful in preempting the debate by reformulating quarrels and conflicts within liberalism, so that they appear to have become debates within liberalism, putting in question this or that particular set of attitudes or policies, but not the fundamental tenets of liberalism with respect to individuals and the expression of their preferences. So so-called conservatism and so-called radicalism in these contemporary guises are in general mere stalking-horses for liberalism: the contemporary debate within modern political systems are almost exclusively between conservative liberals, liberal liberals, and radical liberals. There is little place in such political systems for the criticism of the system itself, that is, for putting liberalism in question.
