Such an explanation of the working of our universe is but a hypothesis. Yet after all, it may to some extent help us to understand phenomena otherwise very difficult to explain. Are not the mystics and seers, the inspired poets and prophets, just those whose lives are more in touch than ours with a world we cannot see, often able only imperfectly to express themselves, but yet conscious of vast realities beyond our ken? And may we not to some extent look upon faith as such a faculty, or sixth sense, taking hold of the unseen and translating it into our own life? But all have not this faith, it may be urged; it is strongest often when the intellectual powers are weak enough, and men of the greatest genius tell us they are wholly without it. Yet cannot we conceive of a community of people almost wholly devoid of one of our own five senses, say that of hearing? How difficult it would be for one of them whose ears were suddenly opened to explain to his friends the new world about him. Imagine these people watching a skylark, and looking on with astonishment at the joy of the one man who heard it singing. A dull brown bird flying aimlessly up into the air: why should he look on it [p.124] with such wonder? They see all that he sees, and if he should try to explain his feelings as he listens to its song, will they not one and all be convinced that he is mad, or that he is at best only recounting some subjective illusion? If he would convince them, let him translate into terms of sight these curious sensations. He cannot do it, and they can only pity his condition. This may help us to realize how narrow a view that is of life which conceives of this world of our consciousness as the only one which exists. It may even help us to frame a physical hypothesis of another life; but this is not enough for our need. If we are to go to the centre of the problem we must turn not to physical difficulties, but to the moral and spiritual ones. It is above all in its failure to solve the problems of our inward life that the materialistic explanation of the world breaks down. All the explanations thus suggested have been too much akin to the physical one to touch the heart of the problem. It is when we realize the meaning of faith in our own lives here and now, that we cease to trouble about the future. In the realization of the supreme value of goodness, and the infinite meaning of it, we begin to understand that it must endure, in a sense far deeper than mere extension in time or space.
