Colonization of the Mind (Metaphor)

The unguarded takeover of one's inner life by unchecked impressions and external judgments — as if a foreign empire were seizing a personal sovereign state.

In Epictetus's teaching, a mind lacking Prosexia is described as "colonized" — foreign impressions, social opinions, and unconscious reactions occupy the inner space like a hostile occupying power. Virtue consists in reclaiming this inner sovereignty through constant vigilance, restoring the Hegemonikon to its role as absolute ruler of one's own psychic territory.
