I can't decide whether emotions are considered an internal state, sensory or even external (impinging on the dissociative boundary). Perhaps emotions could be classified within multiple states depending on the context or root of the emotion.
I read the paper Making Sense of the Mental Universe, outlining the Markov Blanket model, a couple of times, but there's only brief mention of emotions and feelings on p41 and p42.
This question arised for me after watching a video of B.K's presentation Physics without metaphysical assumptions @ Mind and Agency Conference with the Schmidt Inst.
p.s It's great to be here on the forum to have the opportunity to discuss these matters with other enthusiasts, as somebody who doesn't have any friends or colleagues to chat philosophy with. This is my first post - nice to meet you all

Cheers,
Martin
