Is agency an essential concept for the effective description of life, e.g at the cellular scale? I am sympathetic, as I showed how it arises quite naturally in stochastic systems. See my Phys Rev E paper arxiv.org/abs/2503.15670 Much more to come on this .. !
Why are living things different from nonliving? In this piece for @quantamagazine.bsky.social I argue that it is because they are purposive and goal-directed: a capacity we can productively characterize as agency. www.quantamagazine.org/is-life-just...
