1. Prisoner and loneliness - these two concepts are often confused. In fact, this is a big mistake. Prisoners are not alone. Prison is a great collective, and even the most severe isolation methods cannot separate people from this collective if the person does not isolate himself. ——[Czech] Fuchik's "Report from the Gallows" page 49.

2. Loneliness can make people capable or clumsy. ——[French] Hugo "Labour at Sea" page 25.

3. The synonym of loneliness is death. ——[French] Hugo's "The Man Who Laughs", page 665.

4. People who like loneliness are either beasts or gods. ——[Greece] Aristotle's "Politics", quoted from page 50 of "Bacon on Life".

5. A person who is alone when he falls is unfortunate; because no one can help him up. ——"Old Testament".
