"If we want to set out on the aruous search for the truth, we must all summon up the courage to leave the lines along which we have thought until now and as the first step begin to doubt everything that we previously accepted as correct and true. Can we still afford to close our eyes and stop up our ears because new ideas are supposed to be heretical and absurd?"

It then becomes necessary to stop short and make a choice: Either/Or. Either one drifts with their absurd system of ideas, believing that this is the human community. Or one dissents totally from their system of ideas and stands as a lonely human being. (But luckily one notices that the others are in the same crisis and making the same choices.)
