Within the depth-psychology corpus, ‘Property’ is not treated as a simple legal or economic category but as a term freighted with ontological, psychological, and institutional weight. Plato interrogates whether received notions of private property represent the best ordering of society, framing communal versus private holding as a question of the soul’s education rather than mere expediency. Evagrius and the ascetic tradition, transmitted through Antony, position property as an obstacle to spiritual liberation — ‘propertylessness’ (aktēmosunē) paired with tranquility, so that attachment to goods and attachment to grievance are seen as structurally identical. Benveniste’s etymological investigations reveal that the Indo-European conceptual field linking ‘own,’ ‘self,’ and ‘proper’ (sva-, eigen, proprius) underlies notions of inheritance, succession, and social belonging, making property inseparable from identity and kinship structure. Derrida seizes on the Stirnerian conflation of Eigentum (property) and eigen (own/proper) to expose the rhetorical sleight of hand by which private property is naturalised through etymology. Plotinus addresses property as a metaphysical category, asking whether possession forms a coherent ontological class at all. Dōgen, meanwhile, frames the complete surrender of property as a prerequisite for genuine Zen practice. Together, these voices triangulate a concept whose psychological significance lies precisely at the intersection of selfhood, social belonging, renunciation, and power.
