There are situations when one owes solitude to other people, if only not to bother them. But more than this, the multitude needs solitaries as it needs postmen, doctors, and fishermen. They go out and they send, or bring, something back – even if they send no word and vanish finally from sight. The solitary is as necessary to our common sanity as wilderness, as the forest where no one goes, as the waterfall in a canyon that no one has ever seen or heard.
— Alan Watts from the book, Cloud-hidden whereabouts unknown.
