Something I've often wondered is can other animals suffer some of the same diagnoses people get? Many animal behaviours seen with pets for example seem like Seperation Anxiety, OCD, and whatever things a 'mean dog' might have. But are they actual clinical disorders or just normal variations to personality? And if they aren't disorders like people get, why do people have disorders, but other animals are just condition-response, instinctual, etc.?
Looking at the Personality Disorder section I'm struck thinking, these are just normal variations to personality. If we're gonna say every little variation is a disorder, then the entire human race is mentally ill. Everyone has some quirk, or something that makes them seemingly unique. If we declare everyone who stands apart from the herd as being mentally ill, just what's the definition of 'normal?'
Some examples include: Politicians. Are all politicians suffering from megalomania believing they're the ones who should be in charge of everyone else (especially Presidents and other heads of state.) Are religious clergy all delusional, schitzoprehic, sociopathic (ones wanting religious law enforced instead of secular civil laws?) Yet these are people we make role-models, reverie, and let make life-altering decisions, but are completely sane? How is a person who talks out loud to G-d, but isn't employed as some kind of clergyperson different from an actual clergyperson?
If we looked back into the history books and religious texts, everyone who made it in the a historical record did something out of the ordinary. Everyone in religious texts was having two-way interactions with gods or angels or demons. Yet we never say these people were pathological and instead make them into the best people who ever lived. Whereas individuals who haven't yet done anything remarkable are written-off and marginalized labelled mentally-ill.
Is mental illness just a crock completely, or is it a tool used to suppress extraordinary performance. If someone who talks with G-d is insane, no one's gonna wind up following them around and kicking off a new religion. But minus mental illness being a thing we can label such people with, they would be starting new religions or contributing to existing ones.
