该句使用并列结构描述行为与结果之间的关系。
A goat once successfully walked a tightrope at the mountain peak, and people called it a hero because it accomplished something no one else could do. The second time, the goat attempted the same feat but failed, falling into the valley and dying. People then called it a fool because it did something no one was willing to attempt. This story shows that judging value solely by success or failure is a simplistic and arbitrary view.
山羊在山巅走钢丝成功了，人们称它为英雄，因为它完成了别人无法做到的事情。第二次，山羊再次尝试在山巅走钢丝，却未能成功，坠入山涧摔死，人们又称它为傻瓜，因为它做了别人不愿意做的事情。这个故事说明，仅以成败来评判一个人，是一种过于简单且随意的观念。
