So the word contains an assumption. Scientists speak of committing anthropomorphism as if it were a sin. And to accuse a scientist of being anthropomorphic is very serious indeed. We think that many scientists bend much too far over backward to avoid this sin. Well, one factor is that when people study the unsuspected capacities of animals, thev're often beguiled by the subject of intelligence and sometimes consciousness, and never get past these subjects to that of emotion.
Emotion is also a kind of sticky area.
Quite a few scientists find it embarassing. In the matter of weeping, for example, human weeping has been very little studied. It's not the case that someone has done a study that's supposed to prove that animals don't have emotions. Explain the difference, as you understand it, between the expression of emotion between a human and an animal. So that one should use the same terms when speaking of human and animal behavior.
