"To whom, Watt wondered, was this arrangement due? To Mr. Knott himself? Or to some other person, to a past domestic perhaps of genius for example, or a professional dietician? And if not to Mr. Knott himself but to some other person, (or of course persons), did Mr. Knott know that such an arrangement existed, or did he not? [...] Twelve possibilities occurred to Watt, in this connexion: 1. Mr. Knott was responsible for the arrangement, and knew that he was responsible for the arrangement, and knew that such an arrangement existed, and was content. 2. Mr. Knott was not responsible for the arrangement, but knew who was responsible for the arrangement, and knew that such an arrangement existed, and was content. 3. Mr. Knott was responsible for the arrangement, and knew that he was responsible for the arrangement, but did not know that any such arrangement existed, and was content. 4. Mr. Knott was not responsible for the arrangement, but knew who was responsible for the arrangement, but did not know that such an arrangement existed, and was content. 5. Mr. Knott was responsible for the arrangement, but did not know who was responsible for the arrangement, nor that any such arrangement existed, and was content. 6. Mr. Knott was not responsible for the arrangement, nor knew who was responsible for the arrangement, nor knew that any such arrangement existed, and was content. 7. Mr. Knott was responsible for the arrangement, but did not know who was responsible for the arrangement, and knew that such an arrangement existed, and was content. 8. Mr. Knott was not responsible for the arrangement, nor knew who was responsible for the arrangement, and knew that such an arrangement existed, and was content. 9. Mr. Knott was responsible for the arrangement, but knew who was responsible for the arrangement, and knew that such an arrangement existed, and was content. 10. Mr. Knott was not responsible for the arrangement, but knew that he was responsible for the arrangement, and knew that such an arrangement existed, and was content. 11. Mr. Knott was responsible for the arrangement, but knew who was responsible for the arrangement, but did not know that any such arrangement existed, and was content. 12. Mr. Knott was not responsible for the arrangement, but knew that he was responsible for the arrangement, but did not know that such an arrangement existed, and was content. Other possibilities occurred to Watt, in this connexion, but he put them aside, and quite out of his mind, as unworthy of serious consideration, for the time being."
