But this, again, is a counter-productive approach. Exogenic and Endogenic pathogenesis is inseparable. Mental states increase or decrease the susceptibility to externally induced disease. Talk therapy or abuse (external events) alter the biochemical balance of the brain.

The inside constantly interacts with the outside and is so intertwined with it that all distinctions between them are artificial and misleading. The best example is, of course, medication: it is an external agent, it influences internal processes and it has a very strong mental correlate (=its efficacy is influenced by mental factors as in the placebo effect).

The very nature of dysfunction and sickness is highly culture-dependent.

Societal parameters dictate right and wrong in health (especially mental health). It is all a matter of statistics. Certain diseases are accepted in certain parts of the world as a fact of life or even a sign of distinction (e.g., the paranoid schizophrenic as chosen by the gods). If there is no dis-ease there is no disease. That the physical or mental state of a person CAN be different - does not imply that it MUST be different or even that it is desirable that it should be different. In an over- populated world, sterility might be the desirable thing - or even the occasional epidemic. There is no such thing as ABSOLUTE dysfunction. The body and the mind ALWAYS function. They adapt themselves to their environment and if the latter changes - they change.

Personality disorders are the best possible responses to abuse. Cancer may be the best possible response to carcinogens. Aging and death are definitely the best possible response to over-population. Perhaps the point of view of the single patient is incommensurate with the point of view of his species - but this should not serve to obscure the issues and derail rational debate.

As a result, it is logical to introduce the notion of "positive aberration". Certain hyper- or hypo- functioning can yield positive results and prove to be adaptive. The difference between positive and negative aberrations can never be "objective". Nature is morally-neutral and embodies no "values" or "preferences". It simply exists. WE, humans, introduce our value systems, prejudices and priorities into our activities, science included. It is better to be healthy, we say, because we feel better when we are healthy. Circularity aside - this is the only criterion that we can reasonably employ. If the patient feels good - it is not a disease, even if we all think it is. If the patient feels bad, ego-dystonic, unable to function - it is a disease, even when we all think it isn't. Needless to say that I am referring to that mythical creature, the fully informed patient. If someone is sick and knows no better (has never been healthy) - then his decision should be respected only after he is given the chance to experience health.

All the attempts to introduce "objective" yardsticks of health are plagued and philosophically contaminated by the insertion of values, preferences and priorities into the formula - or by subjecting the formula to them altogether. One such attempt is to define health as "an increase in order or efficiency of processes" as contrasted with illness which is "a decrease in order (=increase of entropy) and in the efficiency of processes". While being factually disputable, this dyad also suffers from a series of implicit value-judgements. For instance, why should we prefer life over death? Order to entropy? Efficiency to inefficiency?"
