Methinks the DSM should be working to classify symptoms on the basis of cause (aetiology) anyways. Clades have worked out pretty well for Biology (for example)...

I agree with you (if i understand this
correctly) that it is a matter of practical
convention that doctors categorize mental
illnesses. The names end up being the
thing-- but whether there is a real physical
disorder in the brain that always corresponds
to that name, is another matter. I think
this is the reason for all the MRI shots trying
to say -- here is schizophrenia, here is bipolar
disorder, etc. But that may be just one of the angles of the picture if you like. What if the psychotic process is not a particular disorder of a neuron (like myeletic degeneration, or lesions, or tumour) but rather a chemical process, and
an erratic one at that... i don't think the MRI would pick that up. Working down from the category than up from the symptoms may lead to more mistakes. Hypotheses are like that.
