我们唯一不得不害怕的就是害怕本身。

You don't have to be afraid of what you are !

youdao

我们唯一不得不害怕的就是害怕本身-- 一种莫名其妙、丧失理智的、毫无根据的恐惧，它把人转退为进所需的种种努力化为泡影。

The only thing we have to fear is fear itself - nameless, unreasoning, un justified terror, which paralyzes needed efforts to convert retreat into advance.

因此，让我首先表明我的坚定信念：我们唯一不得不害怕的就是害怕本身--一种莫名其妙、丧失理智的、毫无根据的恐惧，它把人转退为进所需的种种努力化为泡影。

So first of all let me assert my firm belief that the only thing we have to fear is fear itself - nameless, unreasoning, unjustified terror which paralyses efforts to convert retreat into advance.
