“Against stupidity we are defenseless. Neither protests nor the use of force accomplish anything here; reasons fall on deaf ears; facts that contradict one’s prejudgment simply need not be believed—in such moments the stupid person even becomes critical—and when facts are irrefutable they are just pushed aside as inconsequential, as incidental”.
Dietrich Bonhoeffer, Letters and Papers from Prison DBW Vol 8
Dietrich Bonhoeffer (1906–1945) was a German Lutheran pastor, theologian, and anti-Nazi dissident who co-founded the Confessing Church. His influential works on Christianity, including The Cost of Discipleship (1937), remain widely studied. A vocal critic of Nazi policies, he opposed Hitler’s euthanasia program and Jewish persecution. Arrested in 1943 for alleged ties to the 20 July plot, he was executed by hanging in 1945 as the regime collapsed.
