Michael Levin’s study, Technological Approach to Mind Everywhere (TAME), suggests that cognition might exist even in single cells. These cells can make decisions, solve problems, and coordinate their behaviour through bioelectric signals, which challenges the usual assumption that mind and consciousness only reside in brains. If something as simple as a single cell can act with goal-directed behaviour, it makes you wonder, what does it really mean to be conscious?
TAME presents mind not as a yes-or-no property but as a continuum, stretching from simple life forms to complex brains. Consciousness, the framework suggests, might gradually emerge as systems interact with their environment rather than appearing suddenly when a brain forms. Of course, some will object: cells aren’t conscious because they lack neurons, a brain, the hallmarks we usually associate with thinking. But Levin’s approach shows that cognition can arise from the ways a system engages with its surroundings. In that sense, even single cells can display behaviours that look a lot like awareness, planning, or adaptability.
The implications for philosophy of mind are significant. If intelligence and consciousness are not confined to brains, how do we even define them? Could there be awareness in life forms we have never considered sentient? Could future artificial systems or synthetic organisms occupy points on this continuum as well?
By thinking of mind as a spectrum rather than a binary property, TAME encourages us to look for intelligence in unexpected places, from single cells to organisms without central nervous systems. It opens up new questions, not just about consciousness itself, but about ethics, intelligence, and the very definition of life. And while we don’t yet have all the answers, it feels like a shift in perspective is overdue.
