Quote by James Whitcomb Riley
When I see a bird that walks like a duck and swims like a duck and quacks like a duck, I call that bird a duck.
Summary
This quote is suggesting the concept of using observable characteristics to make a logical judgment or identification. It implies that if something exhibits the same behaviors and qualities as a particular object or entity, it can be identified as such. In this case, the speaker identifies a bird as a duck based on its walking, swimming, and quacking resemblance. It highlights the simplicity of relying on observable evidence to draw conclusions, rather than overcomplicating or questioning the obvious.
