Note 156 — Chapter VII

Gissing, the novelist, an acute observer of psychic states, in the most of his books, The Private Papers of Henry Ryecroft, has described this phenomenon: 'Every one, I suppose, is subject to a trick of mind which often puzzles me. I am reading or thinking, and at a moment, without any association or suggestion that I can discover, there rises before me the vision of a place I know. Impossible to explain why that particular spot should show itself to my mind's eye; the cerebral impulse is so subtle that no search may trace its origin.' Gissing proceeds to say that a thought, a phrase, an odour, a touch, a posture of the body, may possibly have furnished the link of association, but he knows no evidence for this theory.
