In this passage, from A Pluralistic Universe, of 1909, a set of lectures by the most eminent of US philosophers William James, expresses very exactly my own view of what is fundamentally wrong with the normal mainstream Christian philosophy. It is telling that these remarks come from a century ago; and of course such matters have become much clearer and more extreme since then.
On the surface level, it is for such reasons that Western culture will not, indeed cannot, go back to traditional forms of Christianity; but the deeper reason is that Man's consciousness has changed, has developed according to divine destiny; and Christians need to - and eventually they will - attain a basic (metaphysical) understanding which reflects this changed consciousness.
The generic term spiritualism, which I began by using merely as the opposite of materialism, thus subdivides into two species, the more intimate one of which is monistic and the less intimate dualistic. The dualistic species is the theism that reached its elaboration in the scholastic philosophy, while the monistic species is the pantheism spoken of sometimes simply as idealism, and sometimes as 'post-kantian' or 'absolute' idealism. Dualistic theism is professed as firmly as ever at all catholic seats of learning, whereas it has of late years tended to disappear at our british and american universities, and to be replaced by a monistic pantheism more or less open or disguised. I have an impression that ever since T.H. Green's time absolute idealism has been decidedly in the ascendent at Oxford. It is in the ascendent at my own university of Harvard.
Absolute idealism attains, I said, to the more intimate point of view; but the statement needs some explanation. So far as theism represents the world as God's world, and God as what Matthew Arnold called a magnified non-natural man, it would seem as if the inner quality of the world remained human, and as if our relations with it might be intimate enough—for what is best in ourselves appears then also outside of ourselves, and we and the universe are of the same spiritual species. So far, so good, then; and one might consequently ask, What more of intimacy do you require? To which the answer is that to be like a thing is not as intimate a relation as to be substantially fused into it, to form one continuous soul and body with it; and that pantheistic idealism, making us entitatively one with God, attains this higher reach of intimacy.
The theistic conception, picturing God and his creation as entities distinct from each other, still leaves the human subject outside of the deepest reality in the universe. God is from eternity complete, it says, and sufficient unto himself; he throws off the world by a free act and as an extraneous substance, and he throws off man as a third substance, extraneous to both the world and himself. Between them, God says 'one,' the world says 'two,' and man says 'three,'—that is the orthodox theistic view. And orthodox theism has been so jealous of God's glory that it has taken pains to exaggerate everything in the notion of him that could make for isolation and separateness. Page upon page in scholastic books go to prove that God is in no sense implicated by his creative act, or involved in his creation. That his relation to the creatures he has made should make any difference to him, carry any consequence, or qualify his being, is repudiated as a pantheistic slur upon his self-sufficingness. I said a moment ago that theism treats us and God as of the same species, but from the orthodox point of view that was a slip of language. God and his creatures are toto genere distinct in the scholastic theology, they have absolutely nothing in common; nay, it degrades God to attribute to him any generic nature whatever; he can be classed with nothing. There is a sense, then, in which philosophic theism makes us outsiders and keeps us foreigners in relation to God, in which, at any rate, his connexion with us appears as unilateral and not reciprocal. His action can affect us, but he can never be affected by our reaction. Our relation, in short, is not a strictly social relation. Of course in common men's religion the relation is believed to be social, but that is only one of the many differences between religion and theology.
This essential dualism of the theistic view has all sorts of collateral consequences. Man being an outsider and a mere subject to God, not his intimate partner, a character of externality invades the field. God is not heart of our heart and reason of our reason, but our magistrate, rather; and mechanically to obey his commands, however strange they may be, remains our only moral duty. Conceptions of criminal law have in fact played a great part in defining our relations with him. Our relations with speculative truth show the same externality. One of our duties is to know truth, and rationalist thinkers have always assumed it to be our sovereign duty. But in scholastic theism we find truth already instituted and established without our help, complete apart from our knowing; and the most we can do is to acknowledge it passively and adhere to it, altho such adhesion as ours can make no jot of difference to what is adhered to. The situation here again is radically dualistic. It is not as if the world came to know itself, or God came to know himself, partly through us, as pantheistic idealists have maintained, but truth exists per se and absolutely, by God's grace and decree, no matter who of us knows it or is ignorant, and it would continue to exist unaltered, even though we finite knowers were all annihilated.
It has to be confessed that this dualism and lack of intimacy has always operated as a drag and handicap on Christian thought. Orthodox theology has had to wage a steady fight within the schools against the various forms of pantheistic heresy which the mystical experiences of religious persons, on the one hand, and the formal or aesthetic superiorities of monism to dualism, on the other, kept producing. God as intimate soul and reason of the universe has always seemed to some people a more worthy conception than God as external creator. So conceived, he appeared to unify the world more perfectly, he made it less finite and mechanical, and in comparison with such a God an external creator seemed more like the product of a childish fancy. I have been told by Hindoos that the great obstacle to the spread of Christianity in their country is the puerility of our dogma of creation. It has not sweep and infinity enough to meet the requirements of even the illiterate natives of India.
Assuredly most members of this audience are ready to side with Hinduism in this matter. Those of us who are sexagenarians have witnessed in our own persons one of those gradual mutations of intellectual climate, due to innumerable influences, that make the thought of a past generation seem as foreign to its successor as if it were the expression of a different race of men. The theological machinery that spoke so livingly to our ancestors, with its finite age of the world, its creation out of nothing, its juridical morality and eschatology, its relish for rewards and punishments, its treatment of God as an external contriver, an 'intelligent and moral governor,' sounds as odd to most of us as if it were some outlandish savage religion.
