• Even though con người is used, it is generally thought of as a noun phrase on its own, and người does not require a classifier because it is itself a classifier (compare Japanese 人 (nin)). Một con người "a person" does not sound dehumanizing, but even literary, while một người sounds casual enough.
• The phrase con người is popularly employed as a philosophical trope or device to bring up discussions about what it means to be human as opposed to being an animal, even though it is not really semantically convincing given the fact that humans are, zoologically, animals, and there are non-animal things going with this classifier.
