Dear PH, I don't have issues with those disciplines -- not at all. But the reason for that is they are all "rigorous" in a way that biology is not, not even to mention the social sciences. The latter of which (I agree with you here) are mainly at the present time, mostly a CROCK...of something or other....
I just don't want to see biological science or any of its cognates fall into the same hole....
Actually biology is pretty rigorous. Perhaps the question you have with it is that it is just fairly recently that we have been able to scientifically examine many of the assumptions which were being made about how organisms work. We have medicines and many cures for ailments which do work. We are learning every day exactly how many things in our bodies occur through very exact experimentation. We do not have all the answers, and we never will but that is true of biology as well as the other sciences.
