“ But let us leave such absurdities, and go on with our analysis of the idea of a necessary and unconditioned being. Immutability excludes perfectibility, so that it is necessary either to suppose the summit of perfection primitively in the necessary being, or to admit that it can never attain this perfection. Perfectibility is one of the characteristics of the contingent, which improves its mode of being by a series of transformations; the absolutely necessary is what it is, and can be nothing else. ”
