alt Hacker NewsLet legal definition of agent is broad:
agent is defined as a person or entity authorized by another (the principal) to act on their behalf and subject to their control, based on the principal's manifestation of assent and the agent's consent so to act (Restatement (Third) of Agency § 1.01).
Notice is missing from that definition, consciousness, theory of mind, physical form.
It's worth reading all section 1.01, and then cover section 1.04, of that book.. which i know you know isn't binding on anything.
