They communicated about everything from political frustrations/anxieties, to dealing with personal life tragedies, to the dense intricacies of science and the universe, and their differing views on God. John Adams' wife, Abigail Adams, would also chime in with her opinions and write to Jefferson herself...especially when it was to send words of comfort and encouragement.
Other points:
Jefferson and Adams were not as religious as the general citizenry, but Adams moreso than Jefferson...However, whenever they would bring up Scripture or ancient writings, they would often quote it in the original Greek (which both knew how to read and write) ...and finally: a lot of people (including me) say these days, "Oh how sad our founders must be about the state of our country!" --- but they were already face-palming, losing friends, and fed-up with the country and state of the world from the very get-go...wondering if America would even survive...
They were obsessively well-versed in history and because of that, they understood how every great empire or civilization was subject to FALL and CRUMBLE. And so they understood more than anyone, how vulnerable this nascent nation was and is...Most importantly, the wisdom of the ancients lent them an inherent understanding of the cyclical ways of human nature and the mystery that is God's will...
I think Jefferson would be amazed it has lasted this long.
Have a Happy 4th. :)
In 200 years will people still be reading the tweets of out current politicians?
I often feel we are the degenerate offspring of illustrious forefathers. We do have, in general, electricity, soap and cotton undewear for all, so there's that.
I hope you have had a wonderfully happy Independence Day, and wish you many more, with most sincere gratitude.
