ELI5: Explain Like I'm 5

Nonfirstorderizability

So, imagine you have a deck of cards. You have a rule that says you can only look at the top card of the deck. This is like first-order logic, where you only deal with one level of information or one layer of thinking.

But then, imagine you have a different rule where you can look at the top card, and if it's a red card, you can look at the next card. But if it's a black card, you can't look at the next card. Then, if that next card is a number card, you can look at the card after that. This is like non-first-order logic, where you can keep looking deeper and deeper as long as certain conditions are met.

Non-first-order logic is when you have rules or conditions that allow you to look beyond just the first level of information or thinking. It's like having a set of rules that help you go deeper and deeper into a problem or concept to really understand it better.
