It has been well observed, that this tendency of the mind to personify isolated qualities or impulses, was essentially the mythological tendency(647) which had created the religion and expressed itself in the poetry of the Greeks, and possibly contributed to foster Shelley’s sympathies with heathen religion. His mind was peculiarly Greek, simple not complex, imaginative rather than fanciful, abstract not concrete, intellectual not emotional; wanting the many-sidedness of modern taste, partaking of the unity of science rather than the multiformity of nature, like sculpture rather than painting. This mental peculiarity contributed to scepticism by inclining his mind to the pantheistic philosophy, which can never be held save by those whose minds can give being to an abstraction, and is revolting to those who are deeply touched with the Hebrew consciousness of personality and of duty. His philosophy was at first a form of naturalism, which identified God with nature, and made body and spirit co-essential. In this stage he oscillated between the belief of half personified self-moved atoms, or a general pervading spirit of nature. From this stage he passed into a new one, by contact with the philosophy of Hume; and, while admitting the diversity of matter and spirit, yet denied the substantial reality of both. In this state of mind he studied the philosophy of Plato, which was originally designed for doubters somewhat analogous to him; and he readily imbibed the theory that the passing phenomena are types of eternal archetypes, embodiments of eternal realities. But it was Plato’s view of the universe that he accepted, not his view of man; his metaphysics, not his ethics. In none of these three theories is the rule of the universe ascribed to a character, but in each to animated abstractions. They are a pantheistic or mythological view of things.(648) Nor was the effect of this philosophy merely theoretical, for the distorted view of the physical and moral cosmos led him to believe that both should be regulated by the same conditions; that men should have the unconstrained liberty which he thought he saw in material things. Like Rousseau, ascribing moral evil to the artificial laws of society, Shelley proposed to substitute a new order of things, in which man should be emancipated from kings and priests. This philosophy also increased his hatred against the moral order of the world, and especially against Christianity; and led him to regard it as the offshoot of superstition and the impediment to progress. Yet even here, while echoing the irreverent doctrines of the French revolution, he bore an unconscious witness to the majesty of the Christian virtues, in that he could find no nobler type with which to invest his ideal race of men.
