"As every strength may become a weakness (and under some circumstances must) so, on the contrary, may the typical suicide find a strength and a support in his apparent weakness. … Harry … fashioned for himself out of this tendency a philosophy that was actually serviceable to life. He gained strength through familiarity with the thought that the emergency exit stood always open, and became curious, too, to taste his suffering to the dregs. If it went too badly with him he could feel sometimes with a grim malicious pleasure: I am curious to see all the same just how much a man can endure. If the limit of what is bearable is reached, I have only to open the door to escape. There are a great many suicides to whom this thought imparts an uncommon strength."
