Un aphorisme de Gilbert Highet:
The real duty of man is not to extend his power or multiply his wealth beyond his needs, but to enrich and enjoy his imperishable possession: his soul.
Traduction automatique:
Le véritable devoir de l’homme est de ne pas étendre son pouvoir ou de multiplier sa fortune au-delà de ses besoins, mais à enrichir et à profiter de sa possession impérissable: son âme.
