Query: Agency in Physics   I discuss three aspects of the notion of agency from the standpoint of
physics: (i) what makes a physical system an agent; (ii) the reason for
agency's time orientation; (iii) the source of the information generated in
choosing an action. I observe that agency is the breaking of an approximation
under which dynamics appears closed. I distinguish different notions of agency,
and observe that the answer to the questions above differ in different cases. I
notice a structural similarity between agency and memory, that allows us to
model agency, trace its time asymmetry to thermodynamical irreversibility, and
identify the source of the information generated by agency in the growth of
entropy. Agency is therefore a physical mechanism that transforms low entropy
into information. This may be the general mechanism at the source of the whole
information on which biology builds.
