Human nature doesn’t change much; science does, and the change accrues, altering the world irreversibly.

Every interview with a public figure should include the question "What have you been wrong about, and how did that change your views?" The answer will tell us if the person is intellectually honest or a tale spinner with delusions of infallibility.
