Seneca shares with us in this quote his own perspective of Good and Evil. Seneca shifts how we define good and evil, but his definition doesn’t really embrace the experience of pain.
“But why,” you ask, “does God sometimes allow evil to befall good men?” Assuredly he does not. Evil of every sort he keeps far from them — sin and crime, evil counsel and schemes for greed, blind lust and avarice intent upon another’s goods. The good man himself he protects and delivers: does any one require of God that he should also guard the good mans’ luggage? Nay, the good man himself relieves God of this concern; he despises externals.
