The work has the characteristic of the times in which it was written—diffuseness; but here, if sometimes there is an indulgence in those fancies and colourings of speech of which we become impatient now, we find some of the best illustrations of that happy power of illumination and imagination which we should expect to abound in the works and sermons of such a poet as Watts. The poet and the metaphysician meet, and mutually aid each other in the attempt to enter upon the mysteries of the unseen world; his ideas, perhaps, do not differ greatly from those which are ordinarily entertained amongst us. Franke, the well-known German pietist, was the means of the translation of a portion of the work in Geneva, and the translator said, in introducing the work, that “the preacher had taken occasion of flying with his thoughts into the blessed mansions of the just, and had given not only a very probable and beautiful idea of the glory of a future life in general, but also an enumeration of the many sorts of enjoyments and pleasures that are to be met with there.” But Watts’ “World to Come” is not limited to the work that bears that title. His thoughts perpetually hovered round that fascinating theme. He was constantly, as we find in many of his pieces, engaged in attempts to understand the nature of metaphysical substance. Though from Revelation we can only gather that “we know not what we shall be,” yet there are precious hints from which we may obtain all that is sufficient for comfort and for light, especially in the Great Teacher’s promise that “where I am there shall also My servant be,” and the assurance of His apostle that “we shall see Him as He is.” It would not be uninteresting to group together all Watts’ words from his various works illustrating his conception of “The World to Come,” his conjectures concerning the mode of our immortality; thus he presents to us— THE BRAIN BOOK.
