Few vices receive as stark a diagnosis as this one: Paul declares φιλαργυρία 'a root of all kinds of evil' in 1 Timothy 6:10. The compound structure (φίλος + ἄργυρος = loving + silver/money) names the disordered attachment itself, not merely its consequences. Classical Greek recognized this as a defining vice, and Paul's warning proved prophetic—those who crave wealth pierce themselves with many griefs. Interestingly, the semantic domain assignment connects this to 'natural substances' (silver), though its true domain is the human heart's capacity for misplaced devotion.
