The Underground Man is upset about--if I remember correctly--

地下人如果我记得没错的话
he's upset about the fact that

他对二加二等于四这样一个事实
two plus two equals four

感到很苦恼
and there's nothing that he can do about it.

然后他对此束手无措
So he curses existence,

所以他咒骂自己的存在
curses God at having made him so impotent

咒骂上帝让他如此无能
that he can't change the fact that two plus two equals four.

以至于连二加二等于四这件事都无力改变
And another philosopher, Descartes,

另一位哲学家笛卡尔
in thinking about God's omnipotence,

在探讨上帝的全知全能时
thought that it wouldn't

认为上帝作为全能者却无法
be good enough if God as omnipotent couldn't

改变数学的真实性
change the facts of mathematics.

这简直说不过去
