I don’t know why it’s so interesting to me, but if you say the word no/know twice, you construct a surprisingly large space of meaning. Perhaps it strikes me as interesting wordplay or pun based humor.
We have 2^2 = four possible word permutations.
- No no
- Know no
- No know
- Know know
Each of the above can also be ambiguous. I will list out the interpretations I have considered but I expect that there are more.
- There is nothing off limits. There is no no for me.
- No. No I mean it. Really no. No no!
- As a noun. That off limit item is a no no.
- You should know what is off limits.
- Knowing the opposite of the right answer can lead to the right answer (especially true in probability).
- You can’t know. Is Schrodinger’s cat dead?
- You don’t know, but it’s possible that you can learn.
- You are not allowed to have knowledge of that. Classified information.
- Nobody knows anything. Ignorance all around. There is no knowledge anywhere.
- You should know what it means to know.
- You really need to know.
