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.
