'The problem of architecture as I see it, he told a journalist who had come to report on the progress of his surprising creation of ferro‑concrete and aluminium, 'is the problem of all art ‑ the elimination of the human element from the consideration of form. The only perfect building must be the factory, because that is built to house machines, not men. I do not think it is possible for domestic architecture to be beautiful, but I am doing my best. All ill comes from man, he said gloomily; 'please tell your readers that. Man is never beautiful, he is never happy except when he becomes the channel for the distribution of mechanical forces.

The journalist looked doubtful. 'Now, Professor, he said, 'tell me this. Is it a fact that you have refused to take any fee for the work you are doing, if you don't mind my asking?

'It is not, said Professor Silenus.

'Peer's Sister‑in‑Law Mansion Builder on Future of Architecture, thought the journalist happily. 'Will machines live in houses? Amazing forecast of Professor-Architect.

Professor Silenus watched the reporter disappear down the drive and then, taking a biscuit from his pocket, began to munch.

'I suppose there ought to be a staircase, he said gloomily. 'Why can't the creatures stay in one place? Up and down, in and out, round and round! Why can't they sit still and work? Do dynamos require staircases? Do monkeys require houses? What an immature, self-destructive, antiquated mischief is man! How obscure and gross his prancing and chattering on his little stage of evolution! How loathsome and beyond words boring all the thoughts and self‑approval of his biological by-product! this half‑formed, ill‑conditioned body! this erratic, maladjusted mechanism of his soul: on one side the harmonious instincts and balanced responses of the animal, on the other the inflexible purpose of the engine, and between them man, equally alien from the being of Nature and the doing of the machine, the vile becoming!

Two hours later the foreman in charge of the concrete-mixer came to consult with the Professor. He had not moved from where the journalist had left him; his fawn-like eyes were fixed and inexpressive, and the hand which had held the biscuit still rose and fell to and from his mouth with a regular motion, while his empty jaws champed rhythmically; otherwise he was wholly immobile.

CHAPTER II Interlude in Belgravia

Arthur Potts knew all about King's Thursday and Professor Silenus.

On the day of Paul's arrival in London he rang up his old friend and arranged to dine with him at the Queen's Restaurant in Sloane Square. It seemed quite natural that they should be again seated at the table where they had discussed so many subjects of public importance, Budgets and birth control and Byzantine mosaics. For the first tilne since the disturbing evening of the Bollinger dinner he felt at ease. Llanabba Castle, with its sham castellations and preposterous inhabitants, had sunk into the oblivion that waits upon even the most lurid of nightmares. Here were sweet corn and pimentoes, and white Burgundy, and the grave eyes of Arthur Potts, and there on the peg over his head hung the black hat he had bought in St James's that afternoon. For an evening at least the shadow that has flitted about this narrative under the name of Paul Pennyfeather materialized into the solid figure of an intelligent, well‑educated, well‑conducted young man, a man who could be trusted to use his vote at a general election with discretion and proper detachment, whose opinion on a ballet or a critical essay was rather better than most people's, who could order a dinner without embarrassment and in a creditable French accent, who could be trusted to see to luggage at foreign railway‑stations and might be expected to acquit himself with decision and decorum in all the emergencies of civilized life. This was the Paul Pennyfeather who had been developing in the placid years which preceded this story. In fact, the whole of this book is really an account of the mysterious disappearance of Paul Pennyfeather, so that readers must not complain if the shadow which took his name does not amply fill the important part of hero for which he was originally cast.
