There is a tacit contempt for those whose experience and beliefs don’t fit in to the modern world as neatly as they ought to. And that includes not just people of the past, but people of other cultures who haven’t embraced western modernity, either because of material privation or because of cultural resistance.
It is an odd belief, that somehow we know more about reality and that therefore we realise there is no spiritual dimension to reality – because, what? Because we have functioning capitalist societies that are only occasionally on the verge of complete collapse? Or because we understand the molecular architecture of cells better?
