he readiness for self-sacrifice is contingent on an imperviousness to the realities of life. ...For self-sacrifice is an unreasonable act. ...All active mass movements strive, therefore, to interpose a fact-proof screen between the faithful and the realities of the world. ...by claiming that the ultimate and absolute truth is already embodied in their doctrine and that there is no truth nor certitude outside it. ...To rely on the evidence of senses and of reason is heresy and treason. It is startling to realize how much unbelief is necessary to make belief possible. What we know as blind faith is sustained by innumerable unbeliefs.
