I believe the three (at least) hardest side-problems of “mind and action” I have encountered are:
1. What is a “fact”, how to establish it and what do we mean by “establishing it”? Constantly moving because of time and space and yet, we need them fixed every time we need to think and act.
2. Can we compare two “experiences” (whether within one agent and even harder, between agents)? Infinite open welfare discussion and yet we need it close every time we need to think and act.
3. Is what am I doing useful at scale (how can you scale your help and how do you measure its usefulness?) Realizing being nothing in the existence and yet we need to think otherwise for having meaning in our acts.
