6.7 The Causal Now


"Our everyday ideas about the progression of metnal time are wrong: they leave no room for the fact that every agent has a different causal history." Different agencies have different "senses" of time, some work fast and others work slow. Time now becomes operationalized for an agent as the time between state changes. "The slower an agency operates -- that is, the longer the intervals between each change of state -- the more external signals can arrive inside those intervals."

(NB: Now we have some clues as to the technical nature of an agent. Agents have states; over time (discrete "chunks") external signals arrive as input to the agent; with each time "click" an agent can change its state; slow vs fast agents differ in terms of how long a time "click" lasts.)
