No poem just paradox What we don't know

In addition to poetry, I enjoy paradox. We find the truth in paradox.
I collect paradoxes.
One important paradox:
Learn what you don't know.

The problem and paradox is; we don't know what we don't know. When we learn what we don't know, we think we know what we don't know, but still don't know what we don't know. So us finite mortals have been given an infinite task. To learn what we don't know.

This should keep us humble. Always open to learning what we don't know.
