> How the fluff would they be able to feel all possible types of feelings

They seem to be limited to mapping others' experiences to their own feelings for analogous experiences. For instance, they first mapped giving birth to pleasure. Hardly epic angelic universal empathy powers.

What else is there, though? How do you define the feelings "pleasure" and "pain", distinctly from "goals sought" and "things avoided"? How do you empathize with a really alien intelligence without mapping its behavior and experiences to your own?
