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.

Jung is describing how early family life becomes a template through which the adult psyche later interprets reality. The “little world of childhood” functions as a miniature model: its emotional climate, roles, and implicit rules are internalized and then projected onto wider social life. If the family’s imprint is strong—through intense identification, strict expectations, or powerful emotional bonds—the adult is more likely to “see” the larger world in the same terms, repeating familiar patterns of trust, fear, authority, and belonging. The remark aligns with Jung’s broader ideas about complexes and projection: unresolved childhood dynamics can shape perception and relationships until they are made conscious and integrated.
