The searching-out and thorough investigation of truth ought to be the primary study of man.
Marcus Tullius Cicero"I believe that no characteristic is so distinctively human as the sense of indebtedness we feel, not necessarily for a favor received, but even for the slightest evidence of kindness; and there is nothing so boorish, savage, inhuman as to appear to be overwhelmed by a favor, let alone unworthy of it."
Marcus Tullius Cicero
