Murray Rothbard: "Equality is a very recent notion in the history of human thought"

The current veneration of equality is, indeed, a very recent notion in the history of human thought. Among philosophers or prominent thinkers the idea scarcely existed before the mid-eighteenth century; if mentioned, it was only as the object of horror or ridicule. The profoundly anti-human and violently coercive nature of egalitarianism was made clear in the influential classical myth of Procrustes, who “forced passing travellers to lie down on a bed, and if they were too long for the bed he lopped off those parts of their bodies which protruded, while racking out the legs of the ones who were too short."
