The conversation was with a lady from an African country and she was talking about her tribe. She said she was from the enlightened tribe. My initial reaction was to question her belief in her own superior enlightenment. My subsequent reaction was to question my own level of enlightenment and ask what right I had to question hers.
My feeling is that enlightenment (or whatever metaphysical term you want to use) can only be gained following a long period of introspection and study requiring isolation, peace and calm, something that is sadly lacking in most parts of the modern world. Claiming that we are more enlightened than the ancients where such conditions only required finding the proverbial mountain cave is a bit of a stretch.
It is a very unpopular view, of course, because it is threatening to the self-esteem of my contemporaries who believe that all of the social changes and scientific advances in the past century or so have put us on the cusp of some permanent state of enlightenment. I am sure that we are rather on the cusp of great disaster. No one really likes to think that, but the evidence is pretty obvious in my opinion.
So I would argue that the provider of such an unenlightened exposition is not in a position to be giving such analysis in a meaningful way.
If you are concluding that your kids' generation, and your grandchildren's generation are each successively less intelligent, please take a moment to reflect if that's a generational issue, or just an age issue. Kids do dumb stuff... are you sure that you or your peers weren't doing equivalently dumb things at that age?
But that can't be right measurement. Any test that took a normal person from 1900 at found them to so lacking in intelligence that they can't function in normal life is clearly missing some part of their intelligence. And perhaps that missing something is what you would describe as broad mindedness and robustness.
We have always believed that.
All through the European middle ages people regularly believed (rightly!) that the ancients were wiser than them. Of course they still believed themselves superior because they were Christian -- and were partially right about that too.
I guess I probably should have written something longer and with some caveats.
The trouble is that we are more enlightened.
