The Creativity of Cells: Aneural Irrational Cognition
V. N. Alexander
In “On Having no Head: Cognition throughout Biological Systems” (2016), František Baluška and Michael Levin review the literature on aneural cognition in single-celled organisms, plants, and animal tissue, all of which exhibit abilities for memory, learning, decision-making, and goal-direction. “Cognition,” they argue, need not involve neurons per se. Cells of all kinds appear to be capable of intelligent behavior that emerges from dynamical networks that propagate signals and alter connections in response to the environment—very like neuronal activity. In fact, as Baluška and Levin conclude, neural tissue seems to have merely improved upon ancient mechanisms used by all living systems generally.
This paper extends the exploration of the mechanisms of cognition by considering whether or not aneural cells may be capable of irrational cognition, making associations based on coincidental similarities and circumstantial factors.If aneural cells do harness such semiosic qualities, as with higher-level creativity, this might be how they are able to overcome old algorithms and invent tools for new situations.
