Given the context, I'm somewhat certain that "we" includes most other neuroscientists. For example, I agree with Panksepp, but of course there are many others.

Regarding the "ToM." Clearly, Panksepp's bottom up approach is the gene-cell-tissue-organ-organ system pathway that links sensory input to mammalian behavior. And his top down approach merely requires sensory input that activate genes in this organized pathway. But that's not theory, it's biological fact. And Panksepp addresses how sure we can be of his biological facts. Did you find any factual errors?

mapologist said: "I will never be able to be sure what another body thinks or feels -- unless "our" bodies will be linked directly (brain-to-brain link) perhaps..."

I'm certain (generally, at the very least!) how my mother thought and felt when her favorite cat died, and she cried. At least in this case, I will maintain this certainty by default, until I there is scientific evidence presented to the contrary.
