That's it. Shamans appear in disparate cultures over millenia upon millenia, helping people in astounding and near-inexplicable ways... And modern academia is just like, 'well, they believe in spirits and take drugs so they must be dumb - now off I go to work to pay my $400,000 mortgage, because that's sensible'.

We owe these traditions an astonishing unacknowledged debt, and the people telling us so are ferociously attacked.

It's a shame. And it will change.
