“The basic totalitarian claim: What I know is everything that needs to be known, and if only it were only manifest in the world, the world would become a utopia. I also think that that's the core idea behind the Tower of Babel. It's the idea that we can build a structure that makes the transcendent unnecessary.”

Context: The idea behind structuralism is that there are things we may not know but we can learn how they are related to each other. This has been used by science since it existed and can be extended to a few other studies — linguistics and mythology — but certainly not to everything.
The great speculative structures are made to be broken. There is not one of them that can hope to last more than a few decades, or at most a century or two.

Context: In an extreme view, the world can be seen as only connections, nothing else. We think of a dictionary as the repository of meaning, but it defines words only in terms of other words. I liked the idea that a piece of information is really defined only by what it's related to, and how it's related. There really is little else to meaning. The structure is everything. There are billions of neurons in our brains, but what are neurons? Just cells. The brain has no knowledge until connections are made between neurons. All that we know, all that we are, comes from the way our neurons are connected.
