I think of the long term sustainment of human life as the sustainment of the basest replicators, not the vessels of the replicators themselves.
The vessel, as you and I both know, has a shelf life.
He seems to be talking about the continuation of human life over successive generations which is what our genes do, not what the genetic vessels do.
EDIT: As an aside, our individual bodies (the genetic vessels) are highly resistant to change. The word I’m thinking of is “homeostasis.” I remember reading in your post about failure modes (i think?) all the different ways that homeostasis can be interrupted. I learned a lot from that post, very informative.
I suppose I should have said “Autobiographical memories are not passed on genetically in humans.” I just assumed that since we were talking about human affairs, everyone would know I was talking about human memory and autobiographical memory in particular. But I should’ve been more specific.
I don’t know anything about monarch butterflies, but I’m pretty sure I’m not a monarch butterfly and I don’t think you’re one either and I don’t think the OP was talking about the politics of monarch butterflies in his post.
I’m sure that whatever biological mechanism evolution has crafted to guide butterflies through their migration cycles is quite amazing but human brains don’t come prepackaged with autobiographical memories of their genetic forebears. I cannot recall a single experiential first person recollection of living through my grandparent’s eyes, my parent’s eyes or, for that matter, of my great-grandparent’s eyes. Can you?
This is not to say that I don’t think we pass on genetic hardwiring by the way. I am not an advocate of what Steven Pinker would call the ‘blank slate’ it just doesn’t appear to be the case that autobiographical memory comes pre-packaged. Autobiographical memory does seem to be written over a lifetime for each particular lifetime.
The point of me even saying what I said was to point out that I perceive a space between where I end and everyone else begins even those I’m related to. This distance is punctuated by my own mortality and my awareness of it. I know that I will only be around for just so long. While I suppose at some level I’m programmed to think about my progeny, I can’t help but also consider myself in a more immediate timeframe.
