> It's like neurology. Yes, it's a terribly interesting field, but you'll learn more about the human mind from reading Proust.

I think this is a great metaphor but for very different reasons than you. Reading Proust will help somebody who sits on the sidelines take in the scene of somebody's neurological condition degrading. Studying neurology will help somebody find and (hopefully) cure the disease.

Neurologists save lives, people who sit in armchairs cherishing Proust may enrich themselves but they have no grounds to look down upon those who are getting their hands dirty.
