Gulliver recovers from his near-madness here, but it was originally Swift's plan to follow this second part with the section that now appears as the fourth part, in which Gulliver encounters a still greater disparity than the one between himself and the Brobdingnagians, and comes to feel so greatly inferior that he goes completely mad. It then occurred to Swift to write a satire on contemporary science and he made it the third part in which Gulliver is most nearly a static observer and which breaks the rhythm of what would otherwise have been a tragic progression  downward. The third part contains some of the most striking passages in the book.
