(One correction. The Hubble radius is not constant, so you don't have to
I proposed a bound on happiness (or unhappiness) of K(S2|S1), where S1 is the
state of an intelligence before the reinforcement signal, S2 is the state
afterwards, and K is Kolmogorov complexity. It is intuitive in that a
stronger reinforcement signal induces a greater change in mental state (as
measured by the length of the shortest program that describes the change), and
that it is not possible to experience happiness without memory. By this
definition, happiness would be bounded by the complexity of the intelligence.
