Nature & Animals Quote by Douglas Adams

"If it looks like a duck, and quacks like a duck, we have at least to consider the possibility that we have a small aquatic bird of the family Anatidae on our hands"

About this Quote

Adams takes a homespun test for common sense and deliberately over-engineers it into bureaucratic prose, the way a spaceship manual might describe a spoon. The gag isn’t just that he swaps “duck” for “a small aquatic bird of the family anatidae”; it’s that the confident snap of folk logic gets sanded down into timid institutional hedging: “we have at least to consider the possibility.” Certainty becomes a committee meeting.

The intent is classic Adams: lampoon the modern habit of using technical language as a substitute for clear thinking. The original “duck test” is blunt empiricism: trust your eyes, trust the evidence, stop stalling. Adams keeps the structure but injects a self-protective caution that feels like legal counsel hovering over every sentence. It’s funny because it’s true to how organizations talk when they’re afraid of being wrong, being sued, or being seen as insufficiently rigorous.

The subtext is a critique of performative expertise. Scientific taxonomy (“anatidae”) should add precision, yet here it functions as camouflage, a way to sound authoritative while avoiding commitment. He’s poking at a culture where saying the obvious plainly can be treated as naive, while saying the obvious opaquely passes for sophistication.

Context matters: Adams wrote in an era of expanding technocracy and managerial language, and his fiction thrives on the absurd gap between complex systems and simple realities. The line reads like a mission statement for his comedy: the universe is chaotic, humans respond by inventing jargon, and the jargon mostly helps us avoid admitting we’re just holding a duck.
