For he that wynketh whan he sholde see,
Al wilfully, God lat him nevere thee.
– Geoffrey Chaucer
The Canterbury Tales, The Nun’s Priest’s Tale. He who knowingly blinks when he should see, God let him never thrive, Chauntecleer tells the Fox when he tries to flatter him a second time. He is referring to those who fail to take heed of danger, wilfully, when they should be alert, and God should never let them prosper.
