The only difference, with regard to our own apprehensions, that is not in favour of the latter assertion is that the first miracle we have repeatedly seen, and the last miracle we have not seen. I admit the full weight of this prodigious difference, but surely no man can hesitate a moment in saying that, putting Revelation out of the question, the resurrection of a spiritual body from a natural body, which may be merely one among the many operations of nature which we cannot see, is an event indefinitely more probable than the immortality of man on earth, which is not only an event of which no symptoms or indications have yet appeared, but is a positive contradiction to one of the most constant of the laws of nature that has ever come within the observation of man.
When we extend our view beyond this life, it is evident that we can have no other guides than authority, or conjecture, and perhaps, indeed, an obscure and undefined feeling. What I say here, therefore, does not appear to me in any respect to contradict what I said before, when I observed that it was unphilosophical to expect any specifick event that was not indicated by some kind of analogy in the past. In ranging beyond the bourne from which no traveller returns, we must necessarily quit this rule; but with regard to events that may be expected to happen on earth, we can seldom quit it consistently with true philosophy. Analogy has, however, as I conceive, great latitude.
For instance, man has discovered many of the laws of nature:
analogy seems to indicate that he will discover many more; but no analogy seems to indicate that he will discover a sixth sense, or a new species of power in the human mind, entirely beyond the train of our present observations.
The powers of selection, combination, and transmutation, which every seed shews, are truly miraculous. Who can imagine that these wonderful faculties are contained in these little bits of matter? To me it appears much more philosophical to suppose that the mighty God of nature is present in full energy in all these operations. To this all powerful Being, it would be equally easy to raise an oak without an acorn as with one. The preparatory process of putting seeds into the ground is merely ordained for the use of man, as one among the various other excitements necessary to awaken matter into mind. It is an idea that will be found consistent, equally with the natural phenomena around us, with the various events of human life, and with the successive revelations of God to man, to suppose that the world is a mighty process for the creation and formation of mind. Many vessels will necessarily come out of this great furnace in wrong shapes. These will be broken and thrown aside as useless; while those vessels whose forms are full of truth, grace, and loveliness, will be wafted into happier situations, nearer the presence of the mighty maker.
I ought perhaps again to make an apology to my readers for dwelling so long upon a conjecture which many, I know, will think too absurd and improbable to require the least discussion. But if it be as improbable and as contrary to the genuine spirit of philosophy as I own I think it is, why should it not be shewn to be so in a candid examination? A conjecture, however improbable on the first view of it, advanced by able and ingenious men, seems at least to deserve investigation. For my own part I feel no disinclination whatever to give that degree of credit to the opinion of the probable immortality of man on earth, which the appearances that can be brought in support of it deserve. Before we decide upon the utter improbability of such an event, it is but fair impartially to examine these appearances; and from such an examination I think we may conclude, that we have rather less reason for supposing that the life of man may be indefinitely prolonged, than that trees may be made to grow indefinitely high, or potatoes indefinitely large. Though Mr Godwin advances the idea of the indefinite prolongation of human life merely as a conjecture, yet as he has produced some appearances, which in his conception favour the supposition, he must certainly intend that these appearances should be examined and this is all that I have meant to do.
