As a child I felt myself to be alone, and I am still, because I know things and must hint at things which others apparently know nothing of, and for the most part do not want to know.
The individual disposition is already a factor in childhood; it is innate, and not acquired in the course of a life.
The little world of childhood with its familiar surroundings is a model of the greater world. The more intensively the family has stamped its character upon the child, the more it will tend to feel and see its earlier miniature world again in the bigger world of adult life. Naturally this is not a conscious, intellectual process.
