How did intelligent, cultivated people, then and later, come to excuse these abominations which ordinary simplicity sees for what they are? One answer, of course partial, seems to be the deep shift, anticipated by Rousseau, of moral feeling away from concern for liberty to concern for social justice.
For “social justice” please substitute any of the following: social equality, racial equality (or “justice”), ethnic equality (or “justice”), cultural equality (or “justice”), and economic equality (or “justice”) and you have the motivation behind much of Leftist thought and action. The fact that such equality is a fake “justice,” the fact that it cannot actually be attained by human society, and the fact that all efforts towards achieving it end up profoundly compromising liberty are ignored by its champions, who have as much difficulty now giving up their Utopian dream as they did then.
Perhaps more.
