To build a folly is essentially to do something a second time, something at an inopportune moment. That something is always the memory of something forgotten, about which we can paradoxically say "There it is again."
Follies were misunderstood, purposeless constructions. They were often only small, extravagant gestures in a garden, easily whisking off the imagination to distant lands, a sort of time capsule built to awaken the memory and induce surprise in passers-by. They marked locations, organized secondary paths in a park, or simply predicted the arrival of better times—a demarcation, a sacred spot, a mysterious trail, a hill whose tragic rocky nature begged for a tower, a party, or the arrival of summer.
“It is demonstrably true that things cannot be other than as they are. For, everything having been made for a purpose, everything is necessarily for the best purpose.” — Professor Pangloss
"The combination of a worldwide shift to GM crops and rising global temperatures led to a series of global disasters, destroying many natural resources and causing a permanent environmental imbalance. Earth’s leaders make the choice to outsource all food production to off-world corporately owned farm planets, known as ‘flatlands’." — Luke Sanger on the album Onyx Pyramid
The music, Sanger writes, is a kind of fictional soundtrack for a landscape of offworld megafarms, where a human skeleton crew has been reporting “auditory hallucinations” amplified by the effects of an artificial atmosphere. Audio scifi.
