Question

如题所述

Answer 1

这是美国国防部长拉姆斯菲尔德在去年2月在一次记者招待会上谈到伊拉克是否存在大规模杀伤性武器时向媒体说的一段话：“Reports that say that something hasn't happened always interesting to me , because as we know , there are known knowns ;there are things we know we know . We also know there are known unknows ;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 .”（“我一向对尚未发生的事情的有关报道感兴趣，因为就像我们都知道的那样，有一些众所周知的事情；我们知道一些我们知道的事情。我们还知道一些很明显的未知事情。那就是说，我们知道有些事情我们不知道。但也有没人知道的未知事情——也就是我们不知道的未知事情。”）

Answer 2

有些事我们知道自己知道,
不过也有些不可知的事我们并不知晓.
出自《智慧拾零——拉姆斯菲尔德的存在主义诗集（Pieces
of
Intelligence
:
The
Existential
Poetry
of
Donald
H.
Rumsfeld）》
《不可知》(The
Unknown)
原文如下:
就我们所知
有些事早已众所周知
有些事我们知道自己知道
我们也知道
有些事早已知道是不可知的
也就是说
我们知道有些事我们并不知道
不过也有些不可知的事我们并不知晓
那些我们不知道的事
我们也就不知道
As
we
know,
There
are
known
unknowns.
There
are
things
we
know
we
know.
We
also
know
There
are
known
unknowns.
That
is
to
say
We
know
there
are
somethings
We
do
not
know.
But
there
are
also
unknown
unknowns,
The
ones
we
don’t
know
We
don’t
know.

Answer 3

有知道的东西,固然亦会有不知道的东西.
