For an ideal aristocracy we should not look to Plato’s Republic, for that Utopia is avowedly the ideal only for fallen and corrupt states, since luxury and injustice, we are told, first necessitated war, and the guiding idea of all the Platonic regimen is military efficiency. Aristocracy finds a more ideal expression in theism; for theism imagines the values of existence to be divided into two unequal parts: on the one hand the infinite value of God’s life, on the other the finite values of all the created hierarchy. According to theistic cosmology, there was a metaphysical necessity, if creatures were to exist at all, that they should be in some measure inferior to godhead; otherwise they would have been indistinguishable from the godhead itself according to the principle called the identity of indiscernibles, which declares that two beings exactly alike cannot exist without collapsing into an undivided unit. The propagation of life involved, then, declension from pure vitality, and to diffuse being meant to dilute it with nothingness. This declension might take place in infinite degrees, each retaining some vestige of perfection mixed, as it were, with a greater and greater proportion of impotence and nonentity. Below God stood the angels, below them man, and below man the brute and inanimate creation. Each sphere, as it receded, contained a paler adumbration of the central perfection; yet even at the last confines of existence some feeble echo of divinity would still resound. This inequality in dignity would be not only a beauty in the whole, to whose existence and order such inequalities would be essential, but also no evil to the creature and no injustice; for a modicum of good is not made evil simply because a greater good is elsewhere possible. On the contrary, by accepting that appointed place and that specific happiness, each servant of the universal harmony could feel its infinite value and could thrill the more profoundly to a music which he helped to intone. [Sidenote: A heaven with many mansions.] Dante has expressed this thought with great simplicity and beauty. He asks a friend’s spirit, which he finds lodged in the lowest circle of paradise, if a desire to mount higher does not sometimes visit him; and the spirit replies:
