“Defiance is the reaction against activity (aggression) of the environment.”

Context: An intense, unyielding stubbornness hides beneath an apparent obedience (the patient brings a vast number of dreams; his associations become endless; he produces an inexhaustible number of recollections, which seem to him very important but are actually of little moment; or he goes off upon some byroad suggested by the analyst and leads the latter into a blind alley).
The child manifests the same reactions of defiance and obedience. The child, too, can hide his stubbornness behind an excessive docility (the parent's command: You must be industrious. Industry may become a mania so that the child neither goes out nor has time to sleep). Obedience is the giving up of the resistance; obstinacy the setting up of fresh resistances. This resistance is externally active. We have in recent years had sufficient opportunity to observe the law of resistance (the passive resistance). Activity and defiance show great differences. Defiance is the reaction against activity (aggression) of the environment. It may then manifest itself actively or passively and stands in the service of the defensive tendency of the ego. Every resistance reveals the ego (one's own) in conflict with another.
