What's the meaning of this?

Are you arguing that the classifications themselves are biased?

That's exactly what I and others have been arguing. Now to be clear: it's not that these classifications are wrong, just that out of all possible classifications we could have found, we will most likely find the ones that fit the human perspective of the world.

Think of the Turing test and its criticisms; it's kind of has the same issues.

PS: I've upvoted every comment of yours; asking questions like this should be encouraged :)

Thanks for taking the time to explain your argument!

Confirmed; thanks vanderZwan.

Classifications are also dependent on the capabilities of the language they are expressed in: https://en.wikipedia.org/wiki/Linguistic_relativity
