From LAWLER 181: Wilde altered this paragraph in every revision.
ZABROUSKI: In the 1891 version, Wilde wrote, “Because, without intending it, I have put into it some expression of all this curious artistic idolatry, of which, of course, I have never cared to speak to him. He knows nothing about it. He shall never know anything about it. But the world might guess it, and I will not bare my soul to their shallow prying eyes. My heart shall never be put under their microscope. There is too much of myself in the thing, Harry—too much of myself!” In the original manuscript, Wilde had (after "But the world might guess it") "where there is merely love, they would see something evil. Where there is spiritual passion, they would suggest something vile." If Wilde kept those two sentences in, it could be assumed that critics would have used it as fuel for their argument on what constitutes a moral vs immoral book.
