infallible

A two-person debate at podiums. A woman on the left points across at a man and says, "Now you're saying higher top marginal tax rates are good? Yesterday, you said they were bad!" The man at the right podium, hand on his chest, replies, "Oh, so just because past-me says it, that proves that I used to think it?" A caption beneath reads: "Technically, using your own words against you is a form of argument from authority." In the votey, a close-up shows the man gesturing emphatically as he declares, "Past me was a filthy liar! I'm giving you the straight talk!"
