Feelings vs Emotions (Damasio's Distinction)
Damasio's precise taxonomic distinction: emotions are public, observable patterns of bodily response; feelings are the private, subjective experience of those patterns — and AI can simulate the first without producing the second.
In Damasio's technical vocabulary, emotions and feelings are not synonyms. Emotions are observable patterns of bodily response — facial expressions, postural changes, autonomic activation, hormonal cascades — that can be measured, recorded, and, in principle, imitated by external systems. Feelings are the private, first-person, subjective experience of those patterns — what it is like, from the inside, to undergo the bodily state. The distinction matters enormously for AI: systems can simulate the observable patterns of emotion with increasing fidelity, but simulating the observable pattern is not generating the feeling. The public display and the private experience are different in kind.

The distinction developed across Damasio's trilogy — Descartes' Error (1994), The Feeling of What Happens (1999), and Looking for Spinoza (2003) — with increasing precision. The 2003 treatment is the most refined: emotions are the body doing something measurable; feelings are the mind experiencing that something.
For AI, the distinction
