"A villain must be a thing of power, handled with delicacy and grace. He must be wicked enough to excite our aversion, strong enough to arouse our fear, human enough to awaken some transient gleam of sympathy. We must triumph in his downfall, yet not barbarously nor with contempt, and the close of his career must be in harmony with all its previous development."
"What is there that confers the noblest delight? What is that which swells a man's breast with pride above that which any other experience can bring to him? Discovery! To know that you are walking where none others have walked; that you are beholding what human eye has not seen before; that you are breathing a virgin atmosphere. To give birth to an idea, to discover a great thought -- an intellectual nugget, right under the dust of a field that many a brain-plough had gone over before. To find a new planet, to invent a new hinge, to find a way to make the lightning carry your messages. To be the first -- that is the idea."
