No its not unspoken. Read the paper linked. It explains what you think you are explaining but with scientific rigor.
And you are wrong in your defintion of the world. Attaching human qualities to any non human entity (living or otherwise) is the accepted defintion of what anthropomorphizing is. It does not only apply to non-living entities.
Now I'm the one who's starting to doubt you read my comment with a fraction of the rigor you demand from me reading that incredibly dense paper.
Read it again. I didn't say the definition of the word didn't include living things. The definition of anything is not discussed there at all. The 'unspoken' part applies to what I left implied in my argument, you don't get to rewrite my argument. What I said is that while anthropomorphization is common and can apply to everything, to me it can be a problem when it:
1. Is applied to non-living things with a genuine conviction they are truly living, and not in a ceremonial or casual way
2. Is particularly intense compared to other cases of anthropomorphization and leads to a desire to assign actual personhood to the object
And you are wrong in your defintion of the world. Attaching human qualities to any non human entity (living or otherwise) is the accepted defintion of what anthropomorphizing is. It does not only apply to non-living entities.
