Hello Laurence,
I am honored to have you read my reflections at the IEET and glad you find them worth reflection.
You picked up on an element I hadn't given much space in my essay when:
"I wonder whether the growth and expansion of freedom is more likely, or less likely, than the diminishment of freedom and its eventual extinguishment. "
In my view, the two potentials march in parallel- every increase in our capacity for freedom is an increase in our capacity for oppression, though I am hopeful freedom will better define us.
I suppose the essay's ending reflects the general mood as much as anything and I largely agree with you and John Maynard Keynes that:
"The long run is a misleading guide to current affairs. In the long run we are all dead."
We all must do what good we can even if we know the Second Law, if not our own stupidity will ultimately unravel everything.
All the best,
Rick
