"My idea, mamma, is that all our trouble is because there is so little conscience in people. I see through things, mamma, and I understand. If a man has a stolen shirt I see it. A man sits in a tavern and you fancy he is drinking tea and no more, but to me the tea is neither here nor there; I see further, he has no conscience. You can go about the whole day and not meet one man with a conscience. And the whole reason is that they don't know whether there is a God or not."
