Great blunders are often made, like large ropes, of a multitude of fibers.
[Les fortes sottises sont souvent faites, comme les grosses cordes, d’une multitude de brins.]Victor Hugo (1802-1885) French writer
Les Misérables, Vol. 2 “Cosette,” Book 5 “A Dark Chase Requires a Silent Hound,” ch. 10 “In Which it is explained how Javert lost the Game” (1862) [tr. Wilbour]
Alt. trans. [N. Denny (1980)]: "The greatest blunders, like the thickest ropes, are often compounded of a multitude of strands. Take the rope apart, separate it into the small threads that compose it, and you can break them one by one. You think, 'That is all there was!' But twist them all together, and you have something tremendous." Full text. Cited as Part 2, ch. 5 "Hunt in the Darkness."
