As a boy, I once saw a cart of melons that sorely tempted me. I sneaked up to the cart and stole a melon. I went into the alley to devour it, but no sooner had I set my teeth into it, than I paused, a strange feeling coming over me. I came to a quick conclusion. Firmly, I walked up to that cart, replaced the melon - and took a ripe one.
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.
Franklin said once in one of his inspired flights of malignity--
Early to bed and early to rise
Make a man healthy and wealth and wise.
As if it were any object to a boy to be healthy and wealthy and wise on such terms.
