Amphibology is a fallacy of equivocation, when a statement is made to mean two things. So yeah, a "back-handed compliment" is an amphibology: it means both a compliment and an insult. But all amphibologies are not back-handed compliments. In this case "satisfaction" is taken to mean in one sense "incredible conceit in one's knowledge" (which I fail to see how it differs from what you claim smug satisfaction is) and in another "acknowledgment of one's ultimate incapacity to know everything."
The two senses are not identical, and recognition of this incapacity does not imply resignation.
Heck, the desire to know is so strong (Go ahead, pick up -- or download --a copy of Harry's Metaphysics. The first line is one of the best in human literature) many Christian theologians (and it's the "party line" of the Catholic Church) posit the end of human existence -- what some call heaven -- to be the union of the human intellect with the divine essence, and the concomitant plenitude of knowledge. That's right: Heaven ain't about strumming the harp and endless church potlucks; it's attaining the fullest knowledge possible to a human being. Far from condemning human inquiry into the world, religion is often its strongest supporter.
Not what you were led to believe, is it?
