This book had two authors, and they were both the same person.

Every reader, as he reads, is actually the reader of himself. The writer's work is only a kind of optical instrument he provides the reader so he can discern what he might never have seen in himself without this book. The reader's recognition in himself of what the book says is the proof of the book's truth.

In reality every reader is, while he is reading, the reader of his own self. The writer's work is merely a kind of optical instrument which he offers to the reader to enable him to discern what, without this book, he would perhaps never have perceived in himself.

A man of one book, a student of many.

The true reader must be an extension of the author. He is the higher court that receives the case already prepared by the lower court. The feeling by means of which the author has separated out the materials of his work, during reading separates out again the unformed and the formed aspects of the book — and if the reader were to work through the book according to his own idea, a second reader would refine it still more, with the result that, since the mass that had been worked through would constantly be poured into fresh vessels, the mass would finally become an essential component — a part of the active spirit.

Through impartial rereading of his book the author can refine his book himself. With strangers the particular character is usually lost, because the talent of fully entering into another person’s idea is so rare. Often even in the author himself. It is not a sign of superior education and greater powers to justifiably find fault with a book. When receiving new impressions, greater sharpness of mind is quite natural.

The "I" who speaks in this book is by no means the author. Rather, the author wishes that the reader may come to see himself in this "I": that the reader may not simply relate to what is said here as he would to history, but rather that while reading he will actually converse with himself, deliberate back and forth, deduce conclusions, make decisions like his representative in the book, and through his own work and reflection, purely out of his own resources, develop and build within himself the philosophical disposition that is presented to him in this book merely as a picture.

In reality, every reader is, while reading, the reader of his own self.

Reader, look, Not at his picture, but his book.

"The reader is the space on which all the quotations that make up a writing are inscribed without any of them being lost; a text's unity lies not in its origin but in its destination. Yet this destination cannot any longer be personal: the reader is without history, biography, psychology; he is simply that someone who holds together in a single field all the traces by which the written text is constituted…Classic criticism has never paid any attention to the reader; for it, the writer is the only person in literature…we know that to give writing its future, it is necessary to overthrow the myth: the birth of the reader must be at the cost of the death of the Author. [Final passage in "The Death of the Author," in Image-Music-Text, by Roland Barthes, Trans. Stephen Heath (1977)]"

A writer only begins a book. A reader finishes it.

Beware of the person of one book.

That's why I read, as a stranger,
My being as if it were pages.
Not knowing what will come
And forgetting what has passed,
I note in the margin of my reading
What I thought I felt.
Rereading, I wonder: "Was that me?"
God knows, because he wrote it.
