This is a story which must obviously be told from Strether's point of view, in the first place. The change in his purpose is due to a change in his vision, and the long slow process could not be followed unless his vision were shared by the reader. Strether's predicament, that is to say, could not be placed upon the stage; his outward behaviour, his conduct, his talk, do not express a tithe of it. Only the brain behind his eyes can be aware of the colour of his experience, as it passes through its innumerable gradations; and all understanding of his case depends upon seeing these. The way of the author, therefore, who takes this subject in hand, is clear enough at the outset. It is a purely pictorial subject, covering Strether's field of vision and bounded by its limits; it consists entirely of an impression received by a certain man. There can accordingly be no thought of rendering him as a figure seen from without; nothing that any one else could discern, looking at him and listening to his conversation, would give the full sense of the eventful life he is leading within. The dramatic method, as we ordinarily understand it, is ruled out at once. Neither as an action set before the reader without interpretation from within, nor yet as an action pictured for the reader by some other onlooker in the book, can this story possibly be told. Strether's real situation, in fact, is not his open and visible situation, between the lady in New England and the young man in Paris; his grand adventure is not expressed in its incidents. These, as they are devised by the author, are secondary, they are the extension of the moral event that takes place in the breast of the ambassador, his change of mind. That is the very middle of the subject; it is a matter that lies solely between Strether himself and his vision of the free world. It is a delightful effect of irony, indeed, that he should have accomplished his errand after all, in spite of himself; but the point of the book is not there, the ironic climax only serves to bring out the point more sharply. The reversal of his own idea is underlined and enhanced by the reversal of the young man's idea in the opposite sense; but essentially the subject of the book would be unchanged if the story ended differently, if the young man held to his freedom and refused to go home. Strether would still have passed through the same cycle of unexpected experience; his errand might have failed, but still it would not have been any the more impossible for him to claim his reward, for his part, than it is impossible as things are, with the quest achieved and the young man ready to hasten back to duty of his own accord. And so the subject can only be reached through Strether's consciousness, it is plain; that way alone will command the impression that the scene makes on him. Nothing in the scene has any importance, any value in itself; what Strether sees in it--that is the whole of its meaning.
