problem of the preferred basis in Quantum Mechanics. That is, our
description of a universe is dependent on a measurement basis, but
the theory does not single out any basis as special. For a discussion
of this problem see
Also, have you heard of the Many Minds Interpretation of Quantum
Mechanics, where the problem of the preferred basis (allegedly) does
not arise. See, for example,

above. I would like to insist because that book shed
light on many points which have been discussed here.
I am interested in any comment on that book, which I
find quite interesting.
