Okay, this looks like a good transition point.
I find it odd and somewhat disconcerting to find you so strenuoulsy arguing against the possibilities of freedom and will.
You ain't seen nothin yet brah...,
If in a civilization growing old does not attract respect, it means that in that civilization life as such means nothing. If life is only interesting when I have physical possibilities, then life has no intrinsic value. This too is a sign of a declining civilization. It's a sign that in people, and in the culture as a whole, an authentic search is not there and people have nothing real in which to place their faith and hope. One feels in such older people that, as their automatism is less and less under their control, there's nothing behind it. When you feel there is something behind it you can go on feeling respect even if the outward automatism, even the mind, is not in good order.
