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
For those who read and listen much more than they speak (guilty), an overly-strict Prune filter is applied to their writing; when these people go to write something of their own, their minds don’t produce thoughts nearly as “coherent, witty or wise as their hyper-developed Prune filter is used to processing”.
Hence, my dilemma and an opportunity to break out of this trap. I recognised that if I attempted to write at the quality I was used to reading at, first time every time, my brain would promptly grind to a halt—like trying to brainstorm with a group that laughs at your suggestions.
