Man ever confidently seeks what man has lost. Dependent man and doubting man must have society. That doubt, furthermore, not only creates a motive to social life, even to the restoration of lost companions, but also by weakening the barriers which have divided some class, a sect perhaps, or a party, or a nation, or a race, from some other class, puts social life on a broader and deeper basis, is also an important fact, and full of significance beyond our immediate interest. Thus, to suggest indeed how those two reflections mentioned in the preceding paragraph are inseparable, besides his wish to retain or recover his wonted companions, the doubter would also associate them and himself with new companions, I venture to say, as if in a figure, with Gentiles as well as with Jews, and this gives to doubt, or to those who experience it and adequately use it, a most significant rôle in the evolution of society, the rôle of mediation between old friends and new, between the past and the future, the narrow life and the broader [p.026] and deeper life, what is conservative and what is progressive; but at least for the present it is again enough if we see that doubt, not only by its personal losses gives the motive, but also by its removal of barriers gives the larger possibility of society. And, in addition to the company of nature and the company of man, doubt, springing as it does from man's sense of insufficiency, seeks also the company of God; yet not of the God of any theology. As here conceived, God is that which lies at the back of nature, and at the back of man in the sense of being in character broader and deeper than either of these, and quite superior to any difference between them; he is the single, all-inclusive, wholly indeterminate reality upon which the doubter depends, and must depend; he is as nameless and unspeakable as he is indeterminate and all-inclusive, and he is real and perfect only as so nameless. To theology, God is determinate; to doubt, imperfect if determinate. At times, perhaps only half in earnest, or at least not clearly knowing if he is in earnest or if he wishes others to think him so, the doubter speaks of nature as his God, of the hills, or the fields, or the sea, or the sky, or the busy street as his church, or the great book of the universe as his Bible. At times, with the deepest emotion and with open avowal, nature and God are fully one to him, and the poetry, or the science, or the philosophy, to which his doubting leads him, is veritably a religious revelation. But always his doubting, as he knows it, as he is honest with it, is an appeal, not merely to nature as physically a powerful agent in the life he is pursuing, nor to others like himself who, by sharing, [p.027] may lighten his distress and enhance his final victory, but also to a full, inclusive experience; to a life, perhaps like his own, yet indeterminately deeper than any he has known; to a mind and a heart, such as he knows must be present in
