Note 261 — Chapter XIV
Reading edition
I hope my readers will find themselves able to understand that, as well as this which follows: "What seems preposterous, impossible to us, seemed to him simple fact of observation. When he imagined a street, a house, a room, a figure, he saw it not in the vague schematic way of ordinary imagination, but in the sharp definition of actual perception, all the salient details obtruding themselves on his attention. He, seeing it thus vividly, made us also see it; and believing in its reality however fantastic, he communicated something of his belief to us. He presented it in such relief that we ceased to think of it as a picture. So definite and insistent was the image, that even while knowing it was false we could not help, for a moment, being affected, as it were, by his hallucination."
