Forget ‘I think therefore I am’. In a new theory of embodied consciousness, the neuroscientists Antonio Damasio and Hanna Damasio propose that feelings are the source of consciousness. Long dismissed as secondary to reason, feelings are where consciousness begins. Without them, consciousness is impossible, they argue – with radical implications for the ‘hard problem’ of consciousness and the future of AI.

Please pause for a moment and notice what you are feeling now. Perhaps you notice a growing snarl of hunger in your stomach or a hum of stress in your chest. Perhaps you have a feeling of ease and expansiveness, or the tingling anticipation of a pleasure soon to come. Or perhaps you simply have a sense that you exist. Hunger and thirst, pain, pleasure and distress, along with the unadorned but relentless feelings of existence, are all examples of ‘homeostatic feelings’. Homeostatic feelings are, we argue here, the source of consciousness.

In effect, feelings are the mental translation of processes occurring in your body as it strives to balance its many systems, achieve homeostasis, and keep you alive. In a conventional sense feelings are part of the mind and yet they offer something extra to the mental processes. Feelings carry spontaneously conscious knowledge concerning the current state of the organism as a result of which you can act to save your life, such as when you respond to pain or thirst appropriately. The continued presence of feelings provides a continued perspective over the ongoing body processes; the presence of feelings lets the mind experience the life process along with other contents present in your mind, namely, the relentless perceptions that collect knowledge about the world along with reasonings, calculations, moral judgments, and the translation of all these contents in language form. By providing the mind with a ‘felt point of view’, feelings generate an ‘experiencer’, usually known as a self. The great mystery of consciousness in fact is the mystery behind the biological construction of this experiencer-self.

In sum, we propose that consciousness is the result of the continued presence of homeostatic feelings. We continuously experience feelings of one kind or another, and feelings naturally tell each of us, automatically, not only that we exist but that we exist in a physical body, vulnerable to discomfort yet open to countless pleasures as well. Feelings such as pain or pleasure provide you with consciousness, directly; they provide transparent knowledge about you. They tell you, in no uncertain terms, that you exist and where you exist, and point to what you need to do to continue existing – for example, treating pain or taking advantage of the well-being that came your way. Feelings illuminate all the other contents of mind with the light of consciousness, both the plain events and the sublime ideas. Thanks to feelings, consciousness fuses the body and mind processes and gives our selves a home inside that partnership.
