These unseen causes are now made clear to us by the truths which Vibratory Physics and Sympathetic Philosophy demonstrate and sustain. The prophecy of Dr. Hufeland (made in connection with an account of certain phenomena arising from the unchangeable laws of sympathetic association) is soon to be fulfilled, and the door thrown open to "a new world" of research. Professor Rücker in his papers on "Molecular Forces," William Crookes in his lecture on "The Genesis of Elements," Norman Lockyer in his book on "The Chemistry of the Sun,"--all these scientists have approached so near to this hitherto bolted, double-barred and locked portal that the wonder is not so much that they have approached as that, drawing so near, they have not passed within. Professor Rücker, in his papers (read before the Royal Institution of Great Britain) explaining the attractive and repulsive action of molecules, found himself obliged to apologize to scientists for suggesting the possibility of an intelligence by which alone he could explain certain phenomena unaccounted for by science; but do we not find proof in ourselves that the action of molecules is an intelligent action? For we must admit the individuality of the molecules in our organisms, in order to understand how it is that nourishment maintains life. Try as we may to account for the action of aliment upon the system, all is resolved into the fact that there must be some intelligent force at work. Do we ourselves disunite and intermingle, by myriad channels, in order to rejoin and replace a molecule which awaits this aid? We must either affirm that it is so, that we place them where we think they are needed, or that it is the molecules that find a place of themselves. We know that we are occupied in other ways which demand all our thoughts. It must, therefore, be that these molecules find their own place. Admit this, and we accord life and intelligence to them. If we reason that it is our nerves which appropriate substances that they need for the maintenance of their energy and their harmonious action, we then concede to the nerves what we deny to the molecules. Or, if we think it more natural to attribute this power to the viscera,--the stomach, for example,--we only change the thesis.
