A book is not an isolated entity: it is a narration, an axis of innumerable narrations. One literature differs from another, either before or after it, not so much because of the text as for the manner in which it is read.
Jorge Luis Borges, 1952, For Bernard Shaw.
There is no Frigate like a Book
To take us Lands away
Nor any Coursers like a Page
Of prancing Poetry.
Emily Dickinson, 1955, The Complete Poems, no. 1263
The world is your exercise-book, the pages on which you do your sums.
It is not reality, although you can express reality there if you wish.
You are also free to write nonsense, or lies, or to tear the pages.
