“Ben Bova seems to work very hard at working in new discoveries into his Glum Future but alas, his future is glum and not that well written.”

"Kafka and His Precursors" ["Kafka y sus precursores"], as translated in Labyrinths (1964)
Variant translation: The fact is that all writers create their precursors. Their work modifies our conception of the past, just as it is bound to modify the future.
Other Inquisitions (1952)
Context: 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.

The Man who Tapped the Secrets of the Universe

Opening lines, Ch. 1, "The River Bank"
The Wind in the Willows (1908)
Context: The Mole had been working very hard all the morning, spring-cleaning his little home. First with brooms, then with dusters; then on ladders and steps and chairs, with a brush and a pail of whitewash; till he had dust in his throat and eyes, and splashes of whitewash all over his black fur, and an aching back and weary arms. Spring was moving in the air above and in the earth below and around him, penetrating even his dark and lowly little house with its spirit of divine discontent and longing.
