'No, I don't think we do. We over-estimate it and we under-estimate it. We take the very numerous infractions of our social "bye-laws"--the very necessary and very proper regulations which keep the human company together--and we get frightened at the prevalence of "sin" and "evil." But this is really nonsense. Take theft, for example. Have you any _horror_ at the thought of Robin Hood, of the Highland caterans of the seventeenth century, of the moss-troopers, of the company promoters of our day? 'Then, on the other hand, we underrate evil. We attach such an enormous importance to the "sin" of meddling with our pockets (and our wives) that we have quite forgotten the awfulness of real sin.' 'And what is sin?' said Cotgrave. 'I think I must reply to your question by another. What would your feelings be, seriously, if your cat or your dog began to talk to you, and to dispute with you in human accents? You would be overwhelmed with horror. I am sure of it. And if the roses in your garden sang a weird song, you would go mad. And suppose the stones in the road began to swell and grow before your eyes, and if the pebble that you noticed at night had shot out stony blossoms in the morning? 'Well, these examples may give you some notion of what sin really is.' 'Look here,' said the third man, hitherto placid, 'you two seem pretty well wound up. But I'm going home. I've missed my tram, and I shall have to walk.' Ambrose and Cotgrave seemed to settle down more profoundly when the other had gone out into the early misty morning and the pale light of the lamps. 'You astonish me,' said Cotgrave. 'I had never thought of that. If that is really so, one must turn everything upside down. Then the essence of sin really is----' 'In the taking of heaven by storm, it seems to me,' said Ambrose. 'It appears to me that it is simply an attempt to penetrate into another and higher sphere in a forbidden manner. You can understand why it is so rare. There are few, indeed, who wish to penetrate into other spheres, higher or lower, in ways allowed or forbidden. Men, in the mass, are amply content with life as they find it. Therefore there are few saints, and sinners (in the proper sense) are fewer still, and men of genius, who partake sometimes of each character, are rare also. Yes; on the whole, it is, perhaps, harder to be a great sinner than a great saint.' 'There is something profoundly unnatural about sin? Is that what you mean?'
