From what little I know, their use of schizophrenia is different from how we use it now, and when they refer to the schizophrenic they mean someone who doesn’t systematize and abstract things in order to make sense of the world like most people, so they want to try and use something like this state of mind to observe things as they are rather than reducing them into constituent parts and abstracting their function like we tend to do when analyzing, hence schizoanalysis. I think that’s a neat idea, lmk if I’m misreading.
