A Passage to India, apparently the last, and certainly the best of E. M. Forster's novels, was published twenty-nine years ago, in, 1924. It was accorded instant recognition, as a fine novel and as a perceptive and sympathetic treatment of the problem of “Anglo-India,” The years that followed saw the book established as a modern classic. It has reached a wide audience in the Everyman, Modern Library, and Penguin editions, and has challenged as well the attention of able critics. But, though the novel has received its just dues in many ways, there remains one aspect—and, I think, a fundamental one—still unexplored. It is acknowledged on all sides that thought is the most important element in Forster's novels; yet the dialectical pattern of A Passage to India has never, to my knowledge, been fully and specifically recognised. This omission has resulted not only in a certain incompleteness in critical accounts of the book, but in not a little confusion and obscurity as well.
