As by the fires of experience, so by commission of crime you learn real morals. Commit all crimes, familiarize yourself with all sins, take them in rotation (there are only two or three thousand of them), stick to it, commit two or three every day, and by and by you will be proof against them. When you are through you will be proof against all sins and morally perfect. You will be vaccinated against every possible commission of them. This is the only way.
