"Metaphysics is essentially irrelevant to modern concerns and developments. Indeed this is true across all times and places."

Wow, someone actually believes that.  Then uses the lowest common denominator effect of the herd mentality of various civilizations to justify the belief.  When in effect, they simply illustrate what happens when individuals without connection to "higher order realities" go about amassing the daily bread, at any expense.

That makes me totally irrelevant, for which i am grateful, as it allows me to work hidden from the herd.  I'm sure the all-powerful Church is very grateful to the Alchemists and other hidden metaphysicians, for creating an undercurrent of thought which eventually led to the diminishment of that power.

There wouldn't have been such a cataclysmic upheaval of society in the sixties without the coming together of various powerful new threads of thought, and which included as one thread the metaphysical.
