_Phil_.--Your history of the laws of the inevitable destruction of material forms recalls to my memory our discussion at Adelsberg. The changes of the material universe are in harmony with those which belong to the human body, and which you suppose to be the frame or machinery of the sentient principle. May we not venture to imagine that the visible and tangible world, with which we are acquainted by our sensations, bears the same relation to the Divine and Infinite Intelligence that our organs bear to our mind, with this only difference, that in the changes of the divine system there is no decay, there being in the order of things a perfect unity, and all the powers springing from one will and being a consequence of that will, are perfectly and unalterably balanced. Newton seemed to apprehend, that in the laws of the planetary motions there was a principle which would ultimately be the cause of the destruction of the system. Laplace, by pursuing and refining the principles of our great philosopher, has proved that what appeared sources of disorder are, in fact, the perfecting machinery of the system, and that the principle of conservation is as eternal as that of motion. _The Unknown_.--I dare not offer any speculations on this grand and awful subject. We can hardly comprehend the cause of a simple atmospheric phenomenon, such as the fall of a heavy body from a meteor; we cannot even embrace in one view the millionth part of the objects surrounding us, and yet we have the presumption to reason upon the infinite universe and the eternal mind by which it was created and is governed. On these subjects I have no confidence in reason, I trust only to faith; and, as far as we ought to inquire, we have no other guide but revelation.
