“The management has exploited our wish for infallible systems: here is the water, there is the land, no one can make a mistake. Up to this line there is no danger; on the other side of the line waits certain death. Therefore the alarm wails and the guests flee from their rooms with their clothes fluttering around them. The illusion of complete safety so long as the margin is not reached bears the reverse implication of complete panic once the margin is exceeded. It is easier to choose these sharp demarcation lines than uncertainty in our individual situation; the adjustment has been so small that in itself it is not disastrous, but could contribute to disaster.”
