Winston Churchill said that he could see farther into the future because he looked farther back into the past.
He saw that change is everpresent; the context of situations, beliefs, and technology is forever different, yet patterns can be seen, cycles repeat themselves, the tug of natural forces intrinsic to the universe is constant; commonalities of human nature and behavior remain.
(That people themselves over the cultures and ages carry the same strengths and flaws, and make the same mistakes, is what makes great literature universal and timeless.)
When I look at historical examples from the past, I do so to see what can be used in the context of the ULA. I look at movements at their beginnings and in their early stages; noting later corruptions of the original missions as what to avoid.
Books on the rise of rock n roll and punk are everywhere. Check out the first volume of Andrew Loog Oldham's autobio for an extreme promoter's mindset.
The Foundations of Christianity by Karl Kautsky is a good starting point about that hectic movement. The Gnostic Gospels by Elaine Pagels discusses early struggles and literary conflicts.
For lit movements, Geniuses T0gether by Humphrey Carpenter and Birthing the Beats by Steven Watson are musts.
