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 name, Abode of Fancy, implies a structure created to meet some individual artistic requirement. The tea room is made for the tea master, not the tea master for the tea room. It is not intended for posterity and is therefore ephemeral. The idea that everyone should have a house of his own is based on an ancient custom of & the Japanese race, Shinto superstition ordaining that every dwelling should be evacuated on the death of its chief occupant. Perhaps there may have been some unrealized sanitary reason for this practice. Another early custom was that a newly built house should be provided for each couple that married. It is on account of such customs that we find the Imperial capitals so frequently removed from one site to another in ancient days.
