No one calls a halt on himself, when he begins to be urged ahead; nor does he regulate his alarm according to the truth. No one says; "The author of the story is a fool, and he who has believed it is a fool, as well as he who fabricated it." We let ourselves drift with every breeze; we are frightened at uncertainties, just as if they were certain. We observe no moderation. The slightest thing turns the scales and throws us forthwith into a panic.
