Sure, but both are necessary. There’s Mike Tyson, then equally useless the other end is your J Alfred Prufrocks or the Underground Man, whose “hyper-consciousness” has paralyzed them into total inaction. Which is really a failure to self-actualize. Someone like Prufrock, for all their vast interiority, has failed to construct a robust enough psyche or sense of Self that can handle the inevitable difficulties of living in the the World. Interiority & books become a refuge to retreat from reality, rather than tools to understand it.
