All good points. Yes, after many decades of a borderline smug/self satisfied personal belief mash up of altruistic humanism/borderline and occasionally full on atheism/Thatcher style libertarianism/more recently Blue Labour style politics, I'm realising that humanism is way more connected to Christianity than I was happy to admit.
I have to say I'm moving more and more away from the humans are evolutionary selected for altruism POV. This is pretty much Dawkins view, that we have succeeded as a species and thus select for altruist tendencies. He then throws in group dynamics as a driver.
Stephen Pinker feels that these traits, what you might call "cultural humanity" are also evolved, especially in his specialist area of language and it's common function in mankind.
For me, the humanist ideal seemed to really reflect the evidence as we progressed into the 90s and 00s, organised religion had fewer answers, and a common humanity seemed logical, a belief in "altruistic group dynamics" explaining religious drives and also more and more my more agnostic worldview of people working for the common good. I think I even wore a New Atheist t-shirt, declaring that Dawkins, Hitchins, Pinker and Goldacre had (all) the answer(s).
Then the first chips in this worldview, leading to it somewhat crumbling down for me. Jonathan Haidt's The Coddling Of The American Mind, the growing intersectional analysis change in reading grievances and objectives for all of us to isolated groups. So that the Seattle anti WTO traditional class based movement in late 90s within just a decade had gone from poor v rich and our common good, to whites v blacks, hetero v gay, cis v trans.
Now I'm realising, effectively with the hegemony of elites society sledgehammering trans ideology thru an unsure and unwilling society, that "altruism" and group dynamics really does exist, but not in the way I thought.
Kindness is being weaponised by those who'll force trans ideology on us (SNP and Irish, Canadian, US etc, politicians bending over backwards to justify males in women's prisons), group dynamics as mass pile on purity spirals to force the declared authentic selves of the trans community to crowbar superiority over the long established and equitable rights of a much much larger group ie women.
Q is, can the previous Enlightenment situation ever be recovered?
