"Demons, as you call them, are much more interesting. Nothing is so unattractive as goodness, except, perhaps, a sane mind in a sane body. Even the children find the fairies monotonous, I believe. An eternal smile is much more wearisome than a perpetual frown. The one sweeps away all possibilities, the other suggests a thousand."
"Every one of them sinister."
"Why not? Where would be the drama without the crime? The clash of swords is the music of the world. People talk so much to me about the beauty of confidence. They seem to entirely ignore the much more subtle beauty of doubt. To believe is very dull. To doubt is intensely engrossing. The Apostle Thomas was artistic up to a certain point. He appreciated the value of shadows in a picture. To be on the alert is to live. To be lulled in security is to die."
"But if you pushed that amusing theory to its limits you would arrive at the contradiction in terms—to be happy is to be miserable."
"Certainly. To be what is commonly called happy is a mental complaint demanding careful treatment. The happy people of the world have their value, but only the negative value of foils. They throw up and emphasise the beauty, and the fascination of the unhappy. Scarlet and black are the finest of all the colours. And to cease to doubt is to despair—for a really talented man or woman. That is why people become sceptics. They desire to save themselves from intellectual annihilation."
"Yet the mental pleasure of proving a case may be keen."
"But it cannot be lasting. You do not see the delight that must attend upon conjecture. Let me put it to you in another way. Can you conceive loving a man whom you felt you understood?"
"Certainly. Especially if he were difficult for other people to understand."
"Ah! you begin to appreciate the value of doubt. We often begin by desiring others to enjoy what we shall eventually want for ourselves. The moment we understand a human being, our love for that human being spreads his wings preparatory to flying out of the window."
Lady Locke, who had begun to look earnest, seemed to recollect herself with an effort, and dispelled the gravity that was settling over her face with a smile.
