From BI about the death of a beautiful mind Nash
"....In many cases, these ideas seemed to appear out of thin air.
"Nash was described as having insights before he could
hammer out the proofs of their accuracy, the ideas coming to
him more like revelations than like scholarly findings,"
according to The Washington Post.
Nash was aware of his unusual process, even as his illness got
worse and he began to display irrational behavior, such as
believing he was communicating with aliens. In her biography,
Nasar describes a meeting between Nash and a former
colleague who came to visit him at a mental institution.
"How could you, a mathematician devoted to reason and
logical proof ... believe that extraterrestrials are sending you
messages?" a visitor asked, according to Nasar.
"Because the ideas I had about supernatural beings came to me
the same way my mathematical ideas did," Nash reportedly
replied. "So I took them seriously."
As an author, I understand this entirely too well.
Sometimes, getting a little distance from the voices in your head is a good thing.
