"The famously difficult green-eyed logic puzzle" - I disagree with the proposed solution

[septimus]

By the way, this puzzle was discussed, along with a variety of other puzzles, in a thread from September 2015.

Here’s one of my posts on the topic:

Yes. One of the brown eyes might be greenish and, even though I don’t consider it bluish, another might. Or another might worry that I do.

Or, more to the point, the puzzle requires that we all be perfect logicians, know that we’re all perfect logicians, and know that all the others know that. But isn’t it possible that
we all know that we all know that we all know that we all know that we all know that we all know that we all know that we all know that we are all perfect logicians,
but some of don’t know that
we all know that we all know that we all know that we all know that we all know that we all know that we all know that we all know that we are all perfect logicians.

Although I’ve never fully understand it, I 'believe" in fuzzy logic. Introduce even a tiny bit of fuzziness and this logic puzzle falls apart like a house of cards.
