Word for "being aware that you are unaware"

We are trying to find a word to describe the concept of "being aware that you are unaware," or possibly "knowing that there is more to know." The closest I could come up with was enlightened naivety, but I was hoping that there would be a single word that encompassed the entire meaning.

Solution 1:

"conscious of one's ignorance" comes to mind.

to be conscious of one's ignorance is to be aware of how much you don't know.

e.g.

"if one becomes conscious of one's ignorance" regarding something, it may create a wish to know more about it.

"to be conscious of one's ignorance" is a great step forward.
