Hayek fails to account either for the passion among intellectuals for equality, or for the resulting success of socialists and their egalitarian successors in driving the liberal idea from the stage of politics. This passion for equality is not a new thing, and indeed pre-dates socialism by many centuries, finding its most influential expression in the writings of Rousseau. There is no consensus as to how equality might be achieved, what it would consist in if achieved, or why it is so desirable in the first place. But no argument against the cogency or viability of the idea has the faintest chance of being listened to or discussed by those who have fallen under its spell.
