thinking that you know it纸做的卡纸

Question

英语翻译
Thinking that you know what in fact you don't have is a serious mistake.
怎么翻译这个句子啊?

Answer 1

你自以为知道其实并不知道的事情是一个严重的错误.
That is to say we are all likely to commit a mistake which we thought it was right.Do you remember that Bertrand Russell said ‘thinking that you know when in fact you don’t is a fatal mistake,to which we are all prone.’
