Resumen de Basic Activity
I present a view of activity, taking it that an agent is engaged in activity so long as an action of hers is occurring. I suggest that this view (a) helps in understanding what goes wrong in an argument in Thompson (2008) known sometimes as the �initial segment argument�, and (b) enables us to see that there could be an intelligible conception of what is basic when agents' knowledge is allowed into an account of that.
