"'You have so often and so kindly inquired in your letters after Professor Berger, dear baron, that it will interest you to hear again of this extraordinary man, especially after having made his personal acquaintance here at my house last summer. You may recollect from what he told you in your conversations with him, that his insanity belongs to the class of philosophical aberrations, and that he defended his fixed idea of the absolute non-existence of all things--or rather the great original Naught as he called it--with all the erudition and all the ingenuity which he possesses in so large a degree. My hope to be able to restore this distinguished man in a short time, was unfortunately ill-founded, and I confess that the method which I pursued in his case was, perhaps, not the correct one. I intended to arouse in him, by seclusion, withdrawal of books, etc., a sensation of weariness and loneliness, and through these a desire to see company, to exchange thoughts; in one word, a fondness for life. But I had immensely underrated the fund of inner life which was at the disposal of my patient. He could have lived for years on the treasures of his mind, and the only effect of my efforts was, that he gave himself up more fully than ever to his bottomless, original Naught. Nevertheless, I still hoped for some improvement, a reaction which I thought could not fail to arise in so vigorous a mind as Berger's. About that time--I think it was the very day on which you and Frau von Berkow were here, and I forgot to tell you in the hurry in which you were, anything about these matters which interested me deeply--a visitor, who had announced to me his desire to see Professor Berger, came very _apropos_. This was a young man called Doctor Stein'"--Oldenburg did not look up as he came to the name--"'of whom a colleague in Grunwald, with whom he was travelling, had told me that he had been Berger's favorite and most intimate friend. I hoped the very best results from this visit--a hope which I must confess was considerably weakened when I made the acquaintance of this Doctor Stein. I found him a remarkably handsome, distinguished-looking man, who, however, in spite of evidently rare talents and thorough cultivation, seemed to be completely at odds with the world and himself, as we find this to be the case, unfortunately, but too frequently, more or less, in our most gifted men, thanks to the inactive, thoughtless times in which we live. I ought to have been able to tell myself, if I had maturely reflected, that Berger would not have attached himself so heartily to this man just before the breaking out of his insanity, if he had not also been a hypochondriac. But here he was, and the thing could not be helped now; besides, I had given Doctor Stein very precise instructions before I allowed him to see Berger, and awaited with great interest the result of this interview, at which I was purposely not present. The result was strange indeed.
