Smullyan on Enjoying

He does indeed sift and sort, but he does not know that he is “sifting and sorting.” He is much like a dog who is offered a dish containing a mixture of good foods and bad foods. He spits out the bad foods and eats up the good foods. The doggie does not complain nor criticize the bad foods; he is far too busy enjoying himself hunting out the good foods. And so after the meal is over, if someone asked him how he enjoyed his dinner, the doggie would say, “Delicious! I found so many good foods!” (By contrast, [the grinder] would say, “Horrible! Most of the food was bad! I had a hell of a time finding enough good food to make a meal”)
