Excerpt
Descriptive criteria aside, what is the essence of mental disorders? Are they merely physiological disorders of the brain, or, more precisely of its chemistry? If so, can they be cured by restoring the balance of substances and secretions in that mysterious organ? And, once equilibrium is reinstated – is the illness "gone" or is it still lurking there, "under wraps", waiting to erupt? Are psychiatric problems inherited, rooted in faulty genes (though amplified by environmental factors) – or brought on by abusive or wrong nurturance?

These questions are the domain of the "medical" school of mental health.

Others cling to the spiritual view of the human psyche. They believe that mental ailments amount to the metaphysical discomposure of an unknown medium – the soul. Theirs is a holistic approach, taking in the patient in his or her entirety, as well as his milieu.

The members of the functional school regard mental health disorders as perturbations in the proper, statistically "normal", behaviours and manifestations of "healthy" individuals, or as dysfunctions. The "sick" individual – ill at ease with himself (ego-dystonic) or making others unhappy (deviant) – is "mended" when rendered functional again by the prevailing standards of his social and cultural frame of reference.

In a way, the three schools are akin to the trio of blind men who render disparate descriptions of the very same elephant. Still, they share not only their subject matter – but, to a counter intuitively large degree, a faulty methodology.

As the renowned anti-psychiatrist, Thomas Szasz, of the State University of New York, notes in his article "The Lying Truths of Psychiatry", mental health scholars, regardless of academic predilection, infer the etiology of mental disorders from the success or failure of treatment modalities.
