"I think about it like even numbers. There’s an unlimited number of even numbers but obviously they’re limited, right? Because 3s and 7s aren’t in there. Language is like that. There’s an unlimited number of possible things we can say, of sentence structures, but not anything can be a sentence structure. So you’re absolutely right. Language is unlimited, but it’s unlimited in a limited way."
This is such a tantalizing idea, but there doesn't seem to be anyway to extend it beyond "we don't know what it would be like to think with a different language paradigm, but it would probably be different." I want to know how human thoughts are shaped and constrained by human language.
