I never really understand why people argue about whether animals have emotions. Of course they do. Emotions come from our most primal instincts, and it stands to reason that at least other mammals would have them.

Well... i dont meant that the animals havent emotions. Only that we cant know for sure how they feel, with their animal minds, their emotions. Note that im speaking of the subjective experience of the emotion.
Is the same problem, how can i be sure that i see, lets say, the green color the same way any of you do? I see a color that was said to me that was called "green". And everybody else sees also this color, and calls it "green". But my question is how can i be sure that the "feeling" of green, that undescritible (does this word exist?) sensation my brain "feels" when it sees the green, the subjective perception of it is the same?
Or in other words, if i were able to enter other persons mind, to see the world as they see, does the green would look like the same as it looks like for me? Or, what i call green other person would see as blue, but call it green (cause they learned that color was called green)?
Thats what i mean about the animals emotions. I dont doubt they feel. But i still think its questionable to think they feel it like we do.
