Bear mind that The razor does not exclude more complex hypothesis it merely places the most weight initially on the simpler explanations. Should the simpler explanations fail to describe the problem adequately then they must be modiified or discarded and other less simple explantions must assume favor. One way of stating it has been " There is no need to multiply entities unecessarily." Many rationalists assume the razor forbids ood explanations. Yet often the world is very bizzare in it's workings, certainly complex beyond the ordinary sense of man. Occam's razor makes a good rule of thumb for figuring things out but it is not a hard and fast law of the universe.
