It appears to me that it [sin] is simply an attempt to penetrate into another and higher sphere in a forbidden manner. You can understand why it is so rare. They are few, indeed, who wish to penetrate into higher 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.
