1766, "allege to be of unsound mind" (legal term), from L.L. stultificare "turn into foolishness," from L. stultus "foolish" + root of facere "to make" (see factitious). The first element is cognate with L. stolidus "slow, dull, obtuse" (see stolid). Meaning "cause to appear foolish or absurd" is from 1809.
"Heidegger’s implicit hope was that the human ability to draw a distinction between technological and nontechnological perception would release us from 'the stultified compulsion to push on blindly with technology.'"
