Plato makes the supreme God, creator of the inferior deities, assure these lesser gods that their created nature being in itself subject to dissolution, His will is a surer ground on which to rely for immortality, than the substance or mode of their own being (Timæus, st. p. 41; translated by Cicero, de Univ., xi., and criticised de Nat. Deor., i. 8 and iii. 12).
