But this is a digression. The argument is, that between an individual and any external object with which he has an affective connection, there exists a definite vital flow, as definite and concrete as the electric current whose polarized circuit sets our tram-cars running and our lamps shining, or our Marconi wires vibrating. Whether this object be human, or animal, or plant, or quite inanimate, there is still a circuit. My dog, my canary has a polarized connection with me. Nay, the very cells in the ash-tree I loved as a child had a dynamic vibratory connection with the nuclei in my own centers of primary consciousness. And further still, the boots I have worn are so saturated with my own magnetism, my own vital activity, that if anyone else wear them I feel it is a trespass, almost as if another man used my hand to knock away a fly. I doubt very much if a blood-hound, when it takes a scent, _smells_, in our sense of the word. It receives at the infinitely sensitive telegraphic center of the dog's nostrils the vital vibration which remains in the inanimate object from the individual with whom the object was associated. I should like to know if a dog would trace a pair of quite new shoes which had merely been dragged at the end of a string. That is, does he follow the smell of the leather itself, or the vibration track of the individual whose vitality is communicated to the leather? So, there is a definite vibratory rapport between a man and his surroundings, once he definitely gets into contact with these surroundings. Any particular locality, any house which has been lived in has a vibration, a transferred vitality of its own. This is either sympathetic or antipathetic to the succeeding individual in varying degree. But certain it is that the inhabitants who live at the foot of Etna will always have a certain pitch of life-vibration, antagonistic to the pitch of vibration even of a Palermitan, in some measure. And old houses are saturated with human presence, at last to a degree of indecency, unbearable. And tradition, in its most elemental sense, means the continuing of the same peculiar pitch of vital vibration.
