“Evidently, evildoing also has a threshold magnitude. Yes, a human being hesitates and bobs back and forth between good and evil all his life. He slips, falls back, clambers up, repents, things begin to darken again. But just so long as the threshold of evildoing is not crossed, the possibility of returning remains, and he himself is still within reach of our hope. But when, through the density of evil actions, the result either of their own extreme danger or of the absoluteness of his power, he suddenly crosses that threshold, he has left humanity behind, and without, perhaps, the possibility of return.”

“Cross the threshold, beauty girl," he says."You cross mine," she says back.”

“Evil does not exist; once you have crossed the threshold, all is good. Once in another world, you must hold your tongue.”

“He is not in the habit of explaining himself. He is not in the habit of discussing his successes. But whenever good fortune has called on him, he has been there, planted on the threshold, ready to fling open the door to her timid scratch on the wood.”

“He had the vague sense of standing on a threshold, the crossing of which would change everything.”

“Man’s strength resides in his capacity and desire to elevate himself, so as to attain the good. To travel step by step toward the heights. And that is all he can do. To reach heaven and remain there is beyond his powers: Even Moses had to return to earth. Is it the same for evil?”
