scribner is the first one that's been designed from the granted to do with the project starts with a bunch of fragmented ideas that solely emergent coalesced into a linear structure. and so there's a technological way which that software helps me and has been a big breakthrough over the last three books, and it's much easier. but what has happened is you have to have this time where it's about linearity which is you this long time where the ideas particularly a a book lie this are good ideas, where it any order or sequence. they are just little dots of little nodes recently, loose network. you had the feeling of like there's an interesting thing here about darwin, and there's interesting thing i read about groupthink and janice and there's this other interesting -- and the nodes start to get bigger. something else attaches to the seems related and that another thing attaches to this one and at a certain point which what is look at the whole map and say there's a big cluster here and in the cluster here and the cluster here. maybe those are chapters or maybe those are seconds in one c
