If you don't mind a spoiler, read unenlighteneds answer (which is more or less the canonical answer) and join the debate with us and Michael. — flannel jesus
I don’t think that’s a comparable scenario. I think a minimal example requires 3 blue, 3 brown, and 1 green. — Michael
If it doesn't matter what the green eyed person says, why is his presence required at all? — flannel jesus
I’m not sure, but my reasoning does allow all brown and all blue to leave knowing their eye colour, so either it’s sound or it’s a very lucky coincidence — Michael
But as a question to you, why would it require green saying what everyone already knows? — Michael
I don't think it's sound or a coincidence. I don't think it's correct. — flannel jesus
You have to follow the logic carefully one step at a time to find that out. It's very subtle and honestly strange - that what makes this such a good logic puzzle. It's completely counterintuitive, but also, once you fully grok it, undeniably true. That gives it this really unique flavour as a puzzle. — flannel jesus
One guy, I don’t know who, it might be Baden, takes one of his eyes out, looks at it, and then leaves the island. — T Clark
And yet every blue-eyed person leaves knowing they have blue eyes and every brown-eyed person leaves knowing they have brown eyes. So what do you mean by it “not being correct”? — Michael
You're saying "and yet" as if you've demonstrated that. You haven't — flannel jesus
the reasoning is incomplete — flannel jesus
you haven't justified that it does, is why — flannel jesus
Clever. Obviously everyone could do that to their own eye. That's another loophole answer though - the real answer doesn't involve a loophole — flannel jesus
your reasoning is still based on nothing other than unenlighteneds reasoning, and he's already told you his reasoning is based on the guru saying something. — flannel jesus
There's no reason in your scenario that anybody could figure out their own eye colour. — flannel jesus
Each blue reasons: green sees blue, and so if the two blue I see don’t leave on the second day then I must be blue — Michael
If green eyed person says nothing, what reason would the two blue have to leave on the second day? Without resting on the coattails of unenlightened — flannel jesus
