Equality & Other Goods

From Twilight of Authority by Robert Nisbet:

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.
