  For those of us who do not have Wigner and von Neumann's work on
measurement will you please tell us what is wrong with the idea that a
brain is not necessary for wave function collapse. As far as I can see
this idea makes more snese that attributing some special quality to the
human mind alone which makes it capable of collapsing wave functions.
