| summary | Are we really in control of our actions? Or are we just neural automata, playing out our preprogramming in any moment? Or, even worse, are we just collections of atoms obeying the deterministic laws of physics? These concerns threaten our conception of human free will, and, equally, the more fundamental notion of agency of any organism. How could living organisms – as holistic entities, not just sites of complicated happenings – really act as causal agents in the world? Rather than debating how this could be, in principle, we can ask how did it come to be, in practice. At the most basic level, living systems do thermodynamic work to maintain themselves as entities, out of equilibrium with their environment. Causal slack at the lowest levels of physical reality allowed macroscopic functionalities that favoured organismal persistence to emerge and be selected for. In the simplest organisms, we can see the origins of action and the concomitant emergence of behavioural control systems. Through the evolution of multicellular creatures and the invention of nervous systems, we can follow the transition from pragmatic perception-action couplings to more and more internalised semantic representations. This led, on our lineage, to a trajectory of increasing cognitive depth and ever more sophisticated mapping and modelling of the world and the self, and eventually to the emergence of reflexive thought and metacognition – modelling the mind itself. The resultant accumulation of causal knowledge grants the ability to simulate more complex scenarios, to predict and plan over longer timeframes, to optimise over more competing goals at once, and ultimately to exercise conscious rational control over behaviour. This evolutionary perspective thus provides a way to naturalise agency and free will, without reducing organisms to machines or appealing to any supernatural forces. |
