way in which things are apprehended by us; for when the simple and indivisible original effort of the will exhibits itself as object in our cerebral knowledge, it must appear as an ingenious combination of separate parts, as means and ends of each other, accomplished with wonderful completeness. The _unity of that will_, here referred to, which lies beyond the phenomenon, and in which we have recognised the inner nature of the phenomenal world, is a metaphysical unity, and consequently transcends the knowledge of it, _i.e._, does not depend upon the functions of our intellect, and therefore can not really be comprehended by it. Hence it arises that it opens to the consideration an abyss so profound that it admits of no thoroughly clear and systematically connected insight, but grants us only isolated glances, which enable us to recognise this unity in this and that relation of things, now in the subjective, now in the objective sphere, whereby, however, new problems are again raised, all of which I will not engage to solve, but rather appeal here to the words _est quadam prodire tenus_, more concerned to set up nothing false or arbitrarily invented than to give a thorough account of all;—at the risk of giving here only a fragmentary exposition. If we call up to our minds and distinctly go through in thought the exceedingly acute theory of the origin of the planetary system, first put forth by Kant and later by Laplace, a theory of which it is scarcely possible to doubt the correctness, we see the lowest, crudest, and blindest forces of nature bound to the most rigid conformity to law, by means of their conflict for one and the same given matter, and the accidental results brought about by this produce the framework of the world, thus of the designedly prepared future dwelling‐place of innumerable living beings, as a system of order and harmony, at which we are the more astonished the more distinctly and accurately we come to understand it. For example, if we see that every planet, with its present velocity, can only maintain itself exactly where it actually has its place, because if it were brought nearer to the sun it would necessarily fall into it, or if placed further from it would necessarily fly away from it; how, conversely, if we take the place as given, it can only remain there with its present velocity and no other, because if it went faster it would necessarily fly away from the sun, and if it went slower it would necessarily fall into it; that thus only one definite place is suitable to each definite velocity of a planet; and if we now see this solved by the fact that the same physical, necessary, and blindly acting cause which appointed it its place, at the same time and just by doing so, imparted to it exactly the only velocity suitable for this place, in consequence of the law of nature that a revolving body increases its velocity in proportion as its revolution becomes smaller; and, moreover, if finally we
