It is quite possible that thousands of years from now, forensic cultural criticism will determine that motivational speaking and inspirational books acted upon our minds in much the same way as lead poisoning acted upon the minds of the citizens of the latter Roman Empire. First, it killed brain cells; then it killed a civilization. Now Dave (that's what he wants to be called) would take issue with this and claim that he's just offering some simple, hard-won, home-spun talk about God, honesty, and the spiritual nourishment of fast food. It's not that Dave's advice is stupid (though it is simple), and it's not that Dave's a bad guy (lotta talk about charity). It's that Dave is selling hamburgers. Now that's okay (unless you're a cow), but a cash-register makes a poor pulpit.
