I’ve often wondered what a contemporary free mason movement could be. I know they’re still around but their whole system is wildly arcane.
Freemasonry cannot be modern by definition, but the closest would be liberal Freemasonry where the main rules are 1. Work on yourself with the help of your brothers and sisters (a bit like zen Buddhism), and 2. Apply the rules of Freemasonry in the outside world (mainly don't be an asshole).
