“He looked sharply towards the pollarded trees. 'Yes, just there,' he said. 'I saw it plainly, and equally plainly I saw it not. And then there's that telephone of yours.' I told him now about the ladder I had seen below the tree where he saw the dangling rope. 'Interesting,' he said, 'because it's so silly and unexpected. It is really tragic that I should be called away just now, for it looks as if the - well, the matter were coming out of the darkness into a shaft of light. But I'll be back, I hope, in thirty-six hours. Meantime, do observe very carefully, and whatever you do, don't make a theory. Darwin says somewhere that you can't observe without theory, but to make a theory is a great danger to an observer. It can't help influencing your imagination; you tend to see or hear what falls in with your hypothesis. So just observe; be as mechanical as a phonograph and a photographic lens.'Presently the dog-cart arrived and I went down to the gate with him.'Whatever it is that is coming through, is coming through in bits,' he said. 'You heard a telephone; I saw a rope. We both saw a figure, but not simultaneously nor in the same place. I wish I didn't have to go.'I found myself sympathizing strongly with this wish, when after dinner I found myself with a solitary evening in front of me, and the pledge to 'observe' binding me. It was not mainly a scientific ardour that prompted this sympathy and the desire for independent combination, but, quite emphatically, fear of what might be coming out of the huge darkness which lies on all sides of human experience. I could no longer fail to connect together the fancied telephone bell, the rope, and the ladder, for what made the chain between them was the figure that both Philip and I had seen. Already my mind was seething with conjectural theory, but I would not let the ferment of it ascend to my surface consciousness; my business was not to aid but rather stifle my imagination.
