There are also those who have thought very carefully about the issue
and have come to a hyper-sophisticated philosophical position which
allows them to fudge. I'm thinking particularly of the
consistent-histories gang, including Murray Gell-Mann. I particularly
liked Roland Omnes' version of this: "quantum mechanics can account
for everything except actual facts". He thinks this is a *good* thing!
I don't think it is a good thing to abandon trying to answer questions.
It is the "don't ask" imperative. Actually I do believe Everett (and
Finkelstein, Paulette Fevrier, Graham, Hartle, and many others) are on
the track of succeeding to explain, well, not the actual fact
themselves, but the "correct belief" in "actual-factness".
Note that Omnes justifies some of his views (in particular on the
uniqueness of the universe, or of the outcome of experiments), by
invoking explicitly the abandon of the cartesian program, and accepting
some form of irrationalism.
