Does he? Unless I'm mistaken, I was aware of a doctorate in mathematics from UCLA. I'd be interested to know what the other is in, if there is another.
While I don't think that a doctorate necessarily demonstrates genius, nor that lack of one discredits a person, I think earning a doctorate represents more than mere persistence. Most people don't attend college. Of those who do, many don't graduate. Of those who graduate, most don't or can't get into graduate school. Many of those who get into graduate school wash out. So earning a doctorate is not to be sneezed at, and earning two would be a nice achievement -- though, in some fields (e.g., of the M.D./Ph.D. variety), it's becaming somewhat less rare.
Incidentally, I have not requested that I be referred to as "Dr. Peterson." I'm sure that at least one or two of those calling me "Mr. Peterson" are doing it in order to avoid showing me any more respect than minimal civility absolute requires of them, but it doesn't really bother me. Heck, if the juvenile name-calling from a few of the lesser posters here leaves me unfazed, which it does, calling me "Mr." is scarcely likely to offend me.
