We see a creature near us, and we describe it as a dog. Why that and not "mammal" or "animal"? And if that dog's a Springer Spaniel, and we know it's a Springer Spaniel, why do we nevertheless call it a "dog"?

In an apparent digression, I discuss the idea in cognitive science of a "basic level of categorization" (or abstraction). While we construct hierarchies and taxonomies, we tend to operate at one specific level: one that's not too abstract and not too concrete.
