As telepathy is a conception intermediate between the apparent isolation of minds here communicating only as a rule through material organs, and the ultimate conception of the unity of all mind, so the conception which I am about to propose, of a recognition of space without our concomitant subjection to laws of matter, is strictly intermediate between man's incarnate condition and the condition which we may imagine him ultimately to attain. We cannot possibly infer _a priori_ that all recognition of space must needs disappear with the disappearance of the particular bodily sensations by means of which our conception of space has been developed. But we can imagine that a spirit should be essentially _independent_ of space, and yet capable of recognising it. Provisionally admitting this view, let us consider what range we are now led to assign to inner vision, when it is no longer merely subjective but veridical; bringing news to the percipient of actual fact outside his own organism. We infer that it may represent to us (1) material objects; or (2) symbols of immaterial things; (3) in ways not necessarily accordant with optical laws; and (4) from a point of view not necessarily located within the organism, by means of what I have called a _psychical excursion_. I will take an illustration from a case which is recorded in detail in _Proceedings_ S.P.R., vol. vii. p. 41 [666 C]. A Mrs. Wilmot has a vision of her husband in a cabin in a distant steamer. Besides her husband, she sees in the cabin a stranger (who was in fact present there), with certain material details. Now here I should say that Mrs. Wilmot's inner vision discerned material objects, from a point of view outside her own organism. But, on the other hand, although the perception came to her in visual terms, I do not suppose that it was really _optical_, that it came through the eye. Mrs. Wilmot might believe, say, that her husband's head concealed from her some part of the berth in which he lay; but this would not mean a real optical concealment, but only a special direction of her attention, guided by preconceived notions of what would be optically visible from a given point. As we proceed further we shall see, I think, in many ways how needful is this _excursive_ theory to explain _many_ telepathic and _all_ telæsthetic experiences; _many_, I mean, of the cases where two minds are in communication, and _all_ the cases where the percipient learns material facts (as words in a closed book, etc.) with which no other known mind is concerned.
