More recently, there are books like The Lonely Crowd from the 1960's, [2] and Anthony Storr's Solitude, from the 1980's[3]
Of course, for thousands of years, spending time in solitude has been greatly valued for religious reasons, for "building character", for coming in touch with oneself, or for creative purposes. On the other hand, modern life, and more recently the media (even before social media) have been criticized for alienating people from themselves and from each other.

I seem to recall a title "Solitude and the Self", though I can't find it via Worldcat. There's a similar one from the right timeframe: https://www.worldcat.org/title/solitude-a-return-to-the-self...
Arguably Chiksentmihilyi's work on Flow involves this too.
I think the truth is much more simple. Most people are not highly critical of introverts that prefer quiet and solitude. They may not understand it, but they are mostly indifferent. However, the harsh struggle for the introvert to connect with others on a deeper level leads him/her to that conclusion.
I think the relevant parts are toward the beginning. Full thing's worth listening to, several times. Or you could just read Infinite Jest.
