My most ingenious friend met me one day, and asked me whether I considered I should be richer if I had the ghost of sixpence or if I had not the ghost of sixpence.
“What side do you take?” I inquired, for I knew his disputatious turn.
“I am ready to take either,” he answered; “but I give preference to the ghost.”
“What!” I said. “Give preference to the ghost!”
“Yes. You see, if I haven’t the ghost of sixpence I have nothing at all; but if I have the ghost of a sixpence – ”
“Well?”
“Well, I am the richer by having the ghost of a sixpence.”
“And do you think when you add one more delusion to those under which you already labour” – he and I could never agree about the difference between infinity and zero – “that you will be the better off?”
“I have not admitted a ghost is a delusion; and even if I had I am not prepared to grant that a delusion may not be a source of wealth. Look at the South Sea Bubble.”
I was willing, so there and then we fell to and were at the question – or rather, the questions to which it led – for hours, until we finally emerged upon the crystallization of cast-iron, the possibility of a Napoleonic restoration, or some other kindred matter. How we wandered about and writhed in that talk I can no more remember than I can recall the first articulate words that fell into my life. I know we handled ghosts (it was broad day and in a public street) with a freedom and familiarity that must have been painful to spirits of refinement and reserve. I know we said much about dreams, and compared the phantoms of the open lids with the phantoms of the closed eyes, and pitted them one against another like cocks in a main, and I remember that the case of the dreamer in Boswell’s Johnson came up between us. The case in Boswell submitted to Johnson as an argument in favour of a man’s reason being more acute in sleep than in waking, showed the phantom antagonistic able to floor the dreamer in his proper person. Johnson laughed at such a delusion, for, he pointed out, only the dreamer was besotted with sleep he would have perceived that he himself had furnished the confounding arguments to the shadowy disputant. That is very good, and seems quite conclusive as far as it goes; but is there nothing beyond what Johnson saw? Was there no ghostly prompter in the scene? No suggeritore invisible and inaudible to the dreamer, who put words and notes into the mouth of the opponent? No thinner shade than the spectral being visible in the dream? If in our waking hours we are subject to phantoms which sometimes can be seen and sometimes cannot, why not in our sleeping hours also? Are all ghosts of like grossness, or do some exist so fine as to be beyond our carnal apprehension, and within the ken only of the people of our sleep? If we ponderable mortals are haunted, who can say that our insubstantial midnight visitors may not know wraiths finer and subtler than we, may not be haunted as we are? In physical life parasites have parasites. Why in phantom life should not ghosts have ghosts?
