No doubt, it would be possible to remove, to some extent, the inequalities that are attributable to circumstances, by bringing the best education within the reach of all classes, so that all children might have an equal opportunity of being selected and trained for any functions for which they seemed to be fit: and this seems to be prescribed by ideal justice, in so far as it removes or mitigates arbitrary inequality. Accordingly in those ideal reconstructions of society, in which we may expect to find men's notions of abstract justice exhibited, such an institution as this has generally found a place. Still, there will be much natural inequality which we cannot remove or even estimate.
