It is a fact that humans are multicellular eukaryotes with an internal digestive tract. It is also a fact that these criteria match the biological definition of an animal. But because I’m talking to a philosopher, we even have to argue the definition of “definition”. “A good definition explains concisely what something means“, “a statement expressing the essential nature of something“, “a statement of what a thing is“. So any multicellular eukaryote with an internal digestive tract is in fact an animal by definition. Once we determine that the criteria apply, we have no choice to deny the definition connected with that, especially not when the definition is deliberately well-established by expertise as this one is, rather than being an “accident of language” such as the apologist asserted.
