How do you define The Good? Portia, from The Merchant of Venice, takes a gander at this question that has preoccupied, and has arguably eluded, philosophers for millennia:
“If to do were as easy as to know what were good to do," she observes, "chapels had been churches, and poor men’s cottages princes’ palaces.”
Knowing good vs. doing good -- and if you're able to apply this knowledge into action, why on earth would there ever be a disconnect? (That is a rhetorical question, by the way.)
