As we know,
There are known knowns.
There are things we know we know.
We also know
There are known unknowns.
That is to say
We know there are some things
We do not know.
But there are also unknown unknowns,
The ones we don't know
We don't know.

“据我们所知，有“已知的已知”，有些事，我们知道我们知道；
我们也知道，有 “已知的未知”，也就是说，有些事，我们现在知道我们不知道。
但是，同样存在“未知的未知”—有些事，我们不知道我们不知道。” | x*****i

We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.

芒鞋踏遍陇头云。
归来笑拈梅花嗅，
春在枝头已十分。
