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 labile tastes of certain decision-makers in a company are often a great burden for designers. Too many feel themselves qualified to pass judgment. And how insensitive, how superficial these judgments often are.
Taste, believes Rams, is something that needs to be trained, since the aesthetic decisions at this level in product design are intrinsically bound to the entire form and function of the object. It would be unimaginable, for example, that the management of an aerospace company would ask the designers of a new plane to shorten the wings because they think it would make it look prettier.
