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?
