You're assuming his raising hand had to have contained an ace then, right? Is he that predictable? You made my point, you showed all of your aggression before the ace showed up. By checking that river, you may as well have sent up flares saying, I had a pair that is less than aces now, but I am scared, so bet your pocket sixes and watch me fold!

I said if he calls, it's unlikely you're winning, but do you really want to fold that river for one bet? That takes quite a narrow read that the guy only raises (or bets the river) with an ace. If that's the case, then, sure it's correct to check/fold.
