If, however, one were to urge this solemnly, Mr. Haldane's friends could easily reply that he only gave us such examples on account of the hardness of our hearts. He knew full well their imperfection, but he hoped that to those who would not spontaneously ascend to the Notion of the Totality, these cases might prove a spur and suggest and symbolize something better than themselves. No particular case that can be brought forward is a real concrete. They are all abstractions from the Whole, and of course the "through-and-through" character can not be found in them. Each of them still contains among its elements what we call _things_, grammatical subjects, forming a sort of residual _caput mortuum_ of Existence after all the relations that figure in the examples have been told off. On this "existence," thinks popular philosophy, things may live on, like the winter bears on their own fat, never entering relations at all, or, if entering them, entering an entirely different set of them from those treated of in Mr. Haldane's examples. Thus _if_ the digitalis were to weaken instead of strengthening the heart, and to produce death (as sometimes happens), it would determine itself, through determining the organism, to the function of "kill" instead of that of "cure." The function and relation seem adventitious, depending on what kind of a heart the digitalis gets hold of, the digitalis and the heart being facts external and, so to speak, accidental to each other. But this popular view, Mr. Haldane's friends will continue, is an illusion. What seems to us the "existence" of digitalis and heart outside of the relations of killing or curing, is but a function in a wider system of relations, of which, _pro hac vice_, we take no account. The larger system determines the _existence_ just as absolutely as the system "kill," or the system "cure," determined the _function_ of the digitalis. Ascend to the absolute system, instead of biding with these relative and partial ones, and you shall see that the law of through-and-throughness must and does obtain.
