"In the critic's vocabulary, the word "precursor" is indispensable, but it should be cleansed of all connotations of polemic or rivalry. The fact is that every writer creates his own precursors. His work modifies our conception of the past, as it will modify the future."
-- Essay: "Kafka and his Precursors"
— Jorge Luis Borges

"On the wall next to the table, next to the scones that provided each table with its own circle of lamplight were quotations about reading, her favorite of which was from Kafka: 'A book must be the axe for the frozen sea within us.'"
— Haven Kimmel (The Solace of Leaving Early)

"I think we ought to read only books that bite and sting us. If the book we are reading doesn't shake us awake like a blow on the skull, why bother reading it in the first place? So that it can make us happy, as you put it? Good God, we'd be just as happy if we had no books at all; books that make us happy we could, in a pinch, also write ourselves. What we need are books that hit us like a most painful misfortune, like the death of someone we loved more than we love ourselves, that make us feel as though we had been banished to the woods, far from any human presence, like a suicide. A book must be the axe for the frozen sea within us. That is what I believe. ~quoting Franz Kafka"
— Alberto Manguel (A History of Reading)
