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
I now use Are.na as a Memory Palace, separating my channels into rooms. For example, I have a channel that I call the Computation Room. It’s pretty generic and includes any type of block that relates to computation.
If I notice a pattern in the computation room I create a more specific channel in that room. I think of that more specific topic as an object within the room.
Then there are the adjacent topics that I often find even more exciting to focus on. For those, I choose a name that corresponds with the nature of a room and also its size. For example I have a channel called the Visual Computing Observatory. In my head I am imagining an actual observatory where I am looking and observing and studying a given topic.
