The last sentence suddenly clarifies the difference between the preceding two statements — on surrender as a response to our crisis and surrender and religion — and the chapters that follow: it settles the structure of the book. The two statements still belong to the introduction to surrender—and—catch. But are they not also cases of (surrender or) surrender—to as the last sentence anticipates it in respect to the chapters that follow? Quite so; their chief Service, however, was not to figure as such but as statements on surrender beyond what statements are contained in the pages that precede them. But Won't the chapters that follow also contain additional statements on surrender? Quite so; at their place in the whole, however, their main Service is just as much to illuminate what is surrendered to: by now you ought to feel sufficiently at home with surrender to participate in its exercise, in the surrender to whatever the occasion — the topic of a given chapter.
