They stopped willingly in the midst of their business for recollection, like men in love; they sought to stimulate their imaginations, to focus, as it were, the long vistas of an invisible landscape. If the importunity of affairs or of ill-subdued passions disturbed that dream, they could still return to it at leisure in the solitude of some shrine or under the spell of some canticle or of some sacramental image; and meantime they could keep their faith in reserve as their secret and their resource. The longer the vision lasted and the steadier it became, the more closely, of course, was it intertwined with daily acts and common affections; and as real life gradually enriched that vision with its suggestions, so religion in turn gradually coloured common life with its unearthly light. In the saint, in the soul that had become already the perpetual citizen of that higher sphere, nothing in this world remained without reference to the other, nor was anything done save for a supernatural end. Thus the redemption was actually accomplished and the soul was lifted above the conditions of this life, so that death itself could bring but a slight and unessential change of environment. Morbid as this species of faith may seem, visionary as it certainly was, it is not to be confused with an arbitrary madness or with personal illusions. Two circumstances raised this imaginative piety to a high dignity and made it compatible with great accomplishments, both in thought and in action. In the first place the religious world constituted a system complete and consistent within itself. There was occasion within it for the exercise of reason, for the awakening and discipline of emotion, for the exertion of effort. As music, for all that it contains nothing of a material or practical nature, offers a field for the development of human faculty and presents laws and conditions which, within its sphere, must be obeyed and which reward obedience with the keenest and purest pleasures; so a supernatural religion, when it is traditional and systematic like Christianity, offers another world, almost as vast and solid as the real one, in which the soul may develop. In entering it we do not enter a sphere of arbitrary dreams, but a sphere of law where learning, experience, and happiness may be gained. There is more method, more reason, in such madness than in the sanity of most people. The world of the Christian imagination was eminently a field for moral experience; moral ideas were there objectified into supernatural forces, and instead of being obscured as in the real world by irrational accidents formed an intelligible cosmos, vast, massive, and steadfast. For this reason the believer in any adequate and mature supernatural religion clings to it with such strange tenacity and regards it as his highest heritage, while the outsider, whose imagination speaks another language or is dumb altogether, wonders how so wild a fiction can take root in a reasonable mind.
