It is just as obvious that the animal world won't share it, as the language required to formulate a good juicy rationalization is not available to them.
Not true. Crows communicate using as many as 250 various sounds and even have regional "dialect." They are able to tell each other about hostile faces so other crows recognize people they've never seen before. They pass down information through generations as well.
Not it's not, and if this were the case, there would be no need for psychology at all. Everything would be about chemistry and biology. Those are certainly important aspects, but they do not explain everything. This seems to be a recurring theme with you.
You are ignoring the psychological definition of the word..
Even psychological definitions do not state the attribute is exclusive to humans. And where have I "ignored" the definitions you presented? I said they are valid definitions. Incomplete, but valid nonetheless. You've taken a single definition which is certainly a valid fundamental of psychology and sociology, and tried to argue this is the ONLY valid definition. All I can say is, if you had studied psychology under my professor, you would have failed the course.
