I've seen this and variatiants thereof several times on this list.  Occam's razor is
all very well when you have two theories which equally save the phenomena; but
in physics it is generally extremely difficult to find even one theory which
agrees with all that is known experimentally.  In other fields, philosophy and
psychology, it seems that there are multiple theories which apply to the same
observed phenomena, but the phenomena are so complex and incompletely known and the
 theories so imprecise that it is impossible to really know that the theories are 
consistent with all the phenomena (this seems to be the state of the multi-verse 
hypothesis) and which theory is really 'simpler'; consequently Occam's razor is not so
