Context

“Lord Windermere. What is the difference between scandal and gossip? Cecil Graham. Oh! gossip is charming! History is merely gossip. But scandal is gossip made tedious by morality. Now, I never moralise. A man who moralises is usually a hypocrite, and a woman who moralises is invariably plain. There is nothing in the whole world so unbecoming to a woman as a Nonconformist conscience. And most women know it, I’m glad to say. Lord Augustus. Just my sentiments, dear boy, just my sentiments. Cecil Graham.” source
