" Equality has a built-in revolutionary force lacking in such ideas as justice or liberty. For once the ideal of equality becomes uppermost, it can become insatiable in its demands.
It is possible to conceive of human beings conceding that they have enough freedom or justice in a social order; it is not possible to imagine them ever declaring they have enough equality-once, that is, equality becomes a cornerstone of national policy. In this respect it resembles some of the religious ideals or passions that offer, just by virtue of the impossibility of ever giving them adequate representation in the actual world, almost unlimited potentialities for continuous onslaught against institutions. "
