There are lots of ways to look at problems. Yours is an interesting
way to look at Ockham's razor. I believe that the way that Jim and I
look at it is also interesting. Our two ways do not have to be
exclusive, nor is one "right" and the other "wrong". Each may be
applicable in its own sphere, and each may be useful in understanding
the other.

Best wishes,
