I already said in post above Sacks admits there are many unsolved mysteries, why put the question when you already know there is no answer to it?

I did not say there is no answer. I said Sacks didn't give one.

What you are really saying is, "Do not ask questions to which Oliver Sacks has not provided the answer" ?

A curious policy: The Code of Sacks; The Sacks Barrier.

Besides, I am free to ask questions to which I don't know the answer. That's kind of the point of questions, actually.
