The division is clear, but the reader may exclaim, what nonsense, some dogs are sleeping! Of course, there are also barking and drinking and then, I'm sorry, pissing dogs. But who said that the categories should be comprehensive, where each new level, according to some principle, should embrace the entire remainder of the upper level? We do not know for certain what this variable remainder is. This is the reason for the failure of all claims to a comprehensive classification, as Borges alludes to in his essay. But let's move on. We discover the reason for such attention to dogs paid by an unknown encyclopedist. It's a shame because they have just broken a vase. And the others, agitated like crazy, from afar seem like flies. Indeed, they are circling like mad, like annoying flies. Very poetic. Bravo!
