“There is not a single definition of empathy. The explanandum being heterogeneous, we cannot expect to discover a common mechanism explaining it. What is meant by empathy depends on the basic scientific/clinical/philosophical question. Within the neurosciences, empathy is shifting from a simple automatic bottom- up process to a more complex phenomenon in which different mechanisms (either bottom-up and top-down processing) are involved”. (Massimiliano 11)
