For those who need to be infected that may be true sometimes. But to go to university you have to endure 12 or 13 years of school where everything imaginable is done to stifle any interest you may have had before.
We're not ideal superhumans. For any one of us, being in a stimulating environment makes us better. And a library unfortunately doesn't provide it. Not that books aren't a good companion at any time.
You're implying that schools are a stimulating environment. For me they were the exact opposite and universities perpetuate the same mind numbing system.
