I say that these — which are the laws of mesmerism in its general features — it would be supererogation to demonstrate; nor shall I inflict upon my readers so needless a demonstration; to-day.  My purpose at present is a very different one indeed.  I am impelled, even in the teeth of a world of prejudice, to detail without comment the very remarkable substance of a colloquy, occurring between a sleep-waker and myself.

I had been long in the habit of mesmerizing the person in question, (Mr. Vankirk,) and the usual acute susceptibility and exaltation of the mesmeric perception had supervened.  For many months he had been laboring under confirmed phthisis, the more distressing effects of which had been relieved by my manipulations; and on the night of Wednesday, the fifteenth instant, I was summoned to his bedside.

The invalid was suffering with acute pain in the region of the heart, and breathed with great difficulty, having all the ordinary symptoms of asthma.  In spasms such as these he had usually found relief from the application of mustard to the nervous centres, but to-night this had been attempted in vain.

As I entered his room he greeted me with a cheerful smile, and although evidently in much bodily pain, appeared to be, mentally, quite at ease.

“I sent for you to-night,” he said, “not so much to administer to my bodily ailment, as to satisfy me concerning certain psychal impressions which, of late, have occasioned me much anxiety and surprise.  I need not tell you how sceptical I have hitherto been on the topic of the soul’s immortality.  I cannot deny that there has always existed, as if in that very soul which I have been denying, a vague half-sentiment of its own existence.  But this half-sentiment at no time amounted to conviction.  With it my reason had nothing to do.  All attempts at logical inquiry resulted, indeed, in leaving me more sceptical than before.  I had been advised to study Cousin.  I studied him in his own works as well as in those of his European and American echoes.  The ‘Charles Elwood’ of Mr. Brownson, for example, was placed in my hands.  I read it with profound attention.  Throughout I found it logical, but the portions which were not merely logical were unhappily the initial arguments of the disbelieving hero of the book.  In his summing up it seemed evident to me that the reasoner had not even succeeded in convincing himself.  His end had plainly forgotten his beginning, like the government of Trinculo.  In short, I was not long in perceiving that if man is to be intellectually convinced of his own immortality, he will never be so convinced by the mere abstractions which have been so long the fashion of the moralists of England, of France, and of Germany.  Abstractions may amuse and exercise, but take no hold on the mind.  Here upon earth, at least, philosophy, I am persuaded, will always in vain call upon us to look upon qualities as things.  The will may assent — the soul — the intellect, never.
