Etymology

in- + judicious

adj

   By introducing, into any Composition, Personages and Actions, foreign to each other, an injudicious Author loses that Communication of Emotions, by which alone he can interest the Heart, and raise the Passions to their proper Height and Period. 1748, David Hume, An Enquiry concerning Human Understanding, London: A. Millar, Essay 3, page 45
