- Psych* (psychological/psychiatric) problems exist (I'd be stupid to deny that)
- Many (if not most or even all) psych* problems haven an organic root cause (environmental / dietary / pathogenic / etc.)
- Even those psycho* problems with an established psych* cause (PTSD comes to mind) have an substantial environmental/organic component
- Therefore few (if any at all) psych* problems have a psychiatric root cause, and few are therefore actually psych* problems
- Furthermore, the response of such an psych* problem with an organic cause to psych* treatment will be weak – at best
And as a addendum: Good psych* therapy, with a good understanding of the pathological problems, and a good understanding of its own limitations, can (at best) improve the quality of life – but should be careful not to mistake improved quality of life with an cure.
