‘The transference of emotion is a phenomenon so common, so constantly witnessed, that mankind in general have long ceased to be conscious of its existence, as a thing worth our wonder or consideration, regarding it as being as natural and commonplace as the transference of things that act by the ascertained laws of matter. Nobody, for instance, is surprised, if, when the room is too hot, the opening of a window causes the cold fresh air of outside to be transferred into the room, and in the same way no one is surprised when into the same room, perhaps, which we will imagine as being peopled with dull and gloomy persons, there enters some one of fresh and sunny mind, who instantly brings into the stuffy mental atmosphere a change analogous to that of the opened windows.
