5OI: First Order Ignorance
What is the answer to this question?

First Order Ignorance (1OI)—Lack of Knowledge:
I know that I do not know something. 

With First Order Ignorance, I do not have the answer [1]...  

...but I do have the question—I do have the immediate context [2] in which my lack of knowledge resides.  

Having this contextual knowledge allows me a way out (though I may not have the ability to take it).   

In my music example: if I acknowledge that I do not know how to play Beethoven’s Moonlight Sonata, I would presumably know why.  Perhaps I cannot read the score, perhaps I’ve never heard the piece or paid sufficient attention to know how it sounds, perhaps I don’t have the keyboard skills,…  Knowing which of these items of knowledge I lack allows me to work to acquire them [3].

FOOTNOTES

[1] As an example, I do not know how to speak or understand the Hungarian language.  I am aware of this and could correct it (ie., acquire 0OI) by taking the appropriate lessons followed by some qualification.

[2] As mentioned in 0OI, there are layers upon layers of contextual knowledge.  For 1OI, the question must represent the immediate context level, not a higher, generic context.  For example (from software development): I would demonstrate some level of 1OI with the question "Why did the system crash when we rebooted during startup?"  since the question itself contains specific contextual knowledge.  A much higher, more generic question such as "Why is the system not working?" indicates 2OI rather than 1OI since it only contains non-specific knowledge.

[3] Here again, we see the cascading of knowledge (or lack thereof) that always accompanies the acquisition of knowledge.  It also highlights the process elements of knowledge acquisition: where and how would I source the knowledge I seek to covert my 1OI to 0OI?
