RT, I can't reconcile an increase in disease today with my perception of the past?
Homo sapiens is a young species and while having begun to turn towards organising ourselves for the betterment of all, we remain for the time being at the level of raw recruits working out how to do it. This difficulty is not surprising since no other species has attempted a conscious democratic governance. Brute force was the only rule available.
Religion worked as a political unifier in the past especially when all societies were rigidly class layered but the time for blind faith in the numinous world is rapidly declining. Our species is only just setting out on a real star treck although we've hardly got off our own planet, yet surely, the technology does seem to be pointing in Roddenberry's direction?
If we take the typical life of a human in his or her development as a pattern; It seems to me that humans in the 21st century are collectively at the stage of teenagers still trying out the world, with some more grown up than others. Human society/societies have made progress and religion with faith in holy magic is no longer a beacon for the future.
The next stage toward maturity: will it be built on the foundations set up by the "philosophes" of the 19th century Enlightenment?
