One idea he brings to the table in this book is that somehow before we knew how to behave communally - the indexes and rations by pax of people with "melancholia" or deep sadness were far less troublesome than they are now.
this is an interesting theory. but i'm not so sure i would except that it has
evolutionary benefit as ultimetely depressive behavior is, in
every animal, associated with a higher risk of death. depressed individuals require less resources because they consume less, and they produce less. which is risky, not beneficial.
and we've likely behaved communally since we crawled down from the tree tops, just in different cognetive and linguistic lenses. we've always been the social animal. we just haven't always been a
human animal. when it comes to describing mental illness in terms of evolutionery analysis i think the question is honestly begged.
humans have a whole host of psychopathological behaviors
because we are intelligent. the
more intelligent an animal is, the more psychopathology it gains access to, as we can
think just about any
type of thought we want. and that ultimetely combines with how neurotransmission works and how we respond to our reactions (our inherent subjective emotional states-which the second book you linked touches on vaguely).
and on and on.
there is no evolutionery benefit to depression or anxiety or ptsd or anything else because it results in disordered behavior.
but our brains are probably
primed to respond in specific ways to specific events because of evolutionery influence (such as jumping when you see a snake translating into an overwhelming phobia of harmless snakes.)
i just do not think it is as simple as assuming that every type of physolocigal deficit stems from the same rationale. because that
is rational and a lot of psychopathology
is not rational,
inherently.
things like "panic disorder causing people to fear traveling too far away from home" make no evolutionery sense. because humans migrate when their current conditions are no longer sustenable. and if we had a biological stop on being able to migrate. we would have died out long ago. i think it's hard for me to put into words what i'm thinking exactly. but essentially, a lot of this
does come across as pop psych stuff.
i'd be
more surprised if credible clinicians, neuroscientists and researchers backed this up with the
nuance it deserves. some behaviors are
probably prevelent because they served a purpose, but also, some behaviors are purposeless
because they are pathological. and that is the defining feature of pathology. there is no purpose and there is no reason. it exists irrationally.
and combining with this idea of that it's our
current society that is making every one depressed. as long as we went back to nature the pathology would disappear is something i am inherently skeptical of. as we
are in nature. we are in human nature. there is, however, good evidence to show that we are building technology that is surpassing our brain's ability to fully conceptualize.
which i think is more in line with what you are saying. and how that manifests with regard to pathology across age spectrum and gender and all of that. and i would agree with that which it is revealing specific deficits in our
abilities and not so much that it is
creating anything new that was not there beforehand.
a good example of this is the internet versus our
physical capacity for empathy. we evolved to have about a hundred,
maybe two hundred people in our reletive social groups; and with the internet that number is within the millions, and ergo we see deficits in empathic capacity all across the board when you look at standard internet usege. and that we are biulding weapons, energy resources, and the like.
which that we fundamentally do not understand the consequences to. and this is not to say that technology is the root of all evil but that we nee to be mind full that the top 10% of human intellect that is creating these things, are creating them for the 90% of people who do not really understand how to use them.
which is how innovation works, but when there are no fail safes build in for that. we get exactly what is happening. people who do not know how to read critically are now convinced that the latest 5g update comes from the coronavirus vaccine. and for us as smart individuals we take that for granted. and mock those people but the reality is they don't
know enough to think other things. if they did, they would think them.
and the more wrong and useless information is out there the more wrong and useless behavior we see.
