There are those who don't know who don't know

And those who don't know who think not.

***

There are many of the first,

But the second is most.

***

Then, there are those who know, but not enough,

And those who know who think not.

***

The first is most,

But the second are many.

***

But then there are those who know who don't know,

And there are not enough.
