我很肯定，100年后，我们今天认为是正确无误的事情，很多都会被证明是错误的，甚至可能是令人尴尬的错误，我非常努力地去寻找我今天错在哪里。
I’m positive that in 100 years much of what I take to be true today will be proved to be wrong， maybe even embarrassingly wrong， and I try really hard to identify what it is that I am wrong about today.
Man finds himself only in action.
