Albert Einstein to Sigmund Freud, July 30, 1932: “Is there any way to guide the psychological development of humans so that they become more resistant to the psychoses of hatred and destruction? I am by no means thinking only of the so-called uneducated. From my life experience, it is actually the so-called ‘intelligentsia’ that most easily falls victim to disastrous mass suggestion, because it does not tend to draw directly from experience but rather grasps most conveniently and completely through the printed word.” From "Why War? – An Exchange of Letters between Albert Einstein and Sigmund Freud"
