In olden days, certain people were geniuses at being friendly, mixing a sense of mischief with a keen perception bordering on clairvoyance.
Some people use isolation in an effort to stay in contact with the deeper parts of their mind.
Thoreau, for instance, used Walden as his sanctuary. Even in modern cultures, a real effort is made to raise kids in some level of isolation, letting them follow their dreams and desires as much as possible, giving them an internal atmosphere of hope. It is this inner atmosphere which crystallizes into various formations of mind, which may or may not help the individual later in life. They say poetry is a raid on the inarticulate. Trying to comprehend or understand these deep aspects of consciousness, a person gets the idea they are akin to an exotic art, with many dimensions.
