And the David Foster Wallace quote you requoted was insightful: "Lonely people tend, rather, to be lonely because they decline to bear the psychic costs of being around other humans. They are allergic to people. People affect them too strongly."
You write near the end of your review: "The book clarified for me an important point, though: Solitude is something that we actively seek, while Loneliness is something that we try to escape. Apart from that, they are exactly the same thing: being alone (which in turn is something that happens quite often - in fact, humans are "alone" most of the time)."
Given that, what are your thoughts then on the phrase "alone in a crowd"? For example: https://www.psychologytoday.com/us/blog/the-introverts-corne... "We know loneliness may or may not be related to being alone. Introverts can be perfectly happy alone, or terribly lonely in a crowd. But if introverts are at any particular risk for loneliness, it could be because we set a high bar for friendship. We desire and require deep connections and would rather be lonely alone than in a crowd. But realistically, those deep connections are not easy to find, and if we get caught short and our only choice is superficial socializing or nothing, we can get lonely."
Also, you say the book suggests: "Another of the prevalent journalism theories (internet and social media will result in an increase of individualism and loneliness) seems not to be supported by empirical studies: those who use social media report having a more active social life and more frequent personal interaction with other (outside of social media itself, of course)."
I wonder about that, given the notion of narrowly focused "supernormal stimuli" and how super-fascinating (anti-)social media can potentially displace more holistic human interactions especially over meals. But websites that arrange meetings of people with common interests can counter that trend, so obviously that's not a black and white thing. A related book on that if you are looking for something to summarize next: https://en.wikipedia.org/wiki/Supernormal_Stimuli
Not a self-help book, but a view on loneliness from both an empirical and philosophical perspective.
This book analyzes loneliness (and solitude, the more positive counterpart) to a great detail, and offers some constructive and positive suggestions on how to transform the former into the latter.
