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 world is the totality of facts, not of things.
The world is determined by the facts, and by these being all the facts.
For the totality of facts determines both what is the case, and also all that is not the case.
What we cannot think, that we cannot think: we cannot therefore say what we cannot think.
In fact what solipsism means is quite correct, only it cannot be said, but it shows itself.
That the world is my world, shows itself in the fact that the limits of that language (the language which I understand) mean the limits of my world.
I am my world. (The microcosm.)
The thinking, presenting subject; there is no such thing.
Hence also there can be no ethical propositions.
Propositions cannot express anything higher.
It is clear that ethics cannot be expressed.
Ethics is transcendental.
(Ethics and aesthetics are one.)
My propositions are elucidatory in this way: he who understands me finally recognizes them as senseless, when he has climbed out through them, on them, over them. (He must, so to speak, throw away the ladder, after he has climbed up on it.)
He must surmount these propositions; then he sees the world rightly.
Whereof one cannot speak, thereof one must be silent.
