Stephen: I know the difference btween right and wrong.

Undershaft: You don't say so! What! no capacity for business, no knowledge of law, no sympathy with art, no pretention to philosophy; only a simple knowledge of the secret that has puzzled all the philosophers, baffled all the lawyers, muddled all the men of business, and ruined most of the artists: the secret of right and wrong. Why, man, your a genius, a master of masters, a god! At twenty-four too...You are all alike, you respectable people...You daren't handle high explosives; but you're all too ready to handle honesty and truth and justice and the whole duty of man, and kill one another at that game.
