I cant speak definitively but I think that brethren that joined in the previous century were truly looking for brotherhood and enlightenment and to make themselves better, maybe even for the contacts being a mason indirectly gives you. the brethren that have joined and stuck with it in this century I think were also looking for that, those that have dropped out I think might have come from the millennial conspiracy theory group that were hoping it was more then a dinner club for men. They were hoping we actually ride then sacrifice a goat, worship Lucifer and all that. When they found all that to be hogwash they left.
It's late and I am grumpy, but I used to think Tim was really good, but then I started to wonder if he was writing about an organisation he actually doesn't participate in ? Or am I getting him confused with someone else... there was some well known blogger who used to go on about the problems with lodges, then made the mistake of mentioning he had not been in one for years.
Freemasonry is always going to be new and shiny when you first start, the quality of the lodge and the quality of the brethren will effect how long before you discover some truth, but at some point you are bound to discover it - organizations have problems because they have humans in them...
Although I love history, I will say this - on one real level - who cares about the past. Unless it was rotten (it was generally not) we are bound to romanticize it. What matters is now and how that builds our future for next week, next year and next decade and next century. What matters in that is mentoring and connecting with new members by teaching them our values and creating brotherhood. If Freemasonry has a challenge - it's that we are all time poor and success requires significant investment of time, in ourselves and in each other - especially those we mentor.
