Summary: There should be many essential variables, allowing patterns to endure in proportion
to their suitability, and averaging of the behaviours.
Summary: The elementary conditioned reflex does not need essential variables. Corollary: It is thus a by-product. The Conditioned Reflex : For the elementary conditioned reflex, essential variables are not necessary. 3091.
Summary: The probability of stability. Quotations : "Tous les actes aussi variés soient-ils, n'ont qu'un but, celui de maintenir constantes
les conditions de la vie dans le milieu intérieur." Claude Bernard. 3093. [~ "All such various acts have only one purpose, to maintain the constant conditions
of life in the internal milieu."]
Summary: In an absolute system formed by the junction of independent parts, if a particular
part can take one of ρ initial states and can show σ lines of behaviour from each
initial state, then the quantity of information log2 ρ + log2 σ cannot be exceeded whatever part has been chosen. Information in machines
Summary: Information in an absolute system always falls to log2 η* (3176) where η is the number of the system's stable states and cycles. *Allowance should be made for the fact that the resting states are not equally probable. Information in machines
Summary: When a parameter affects a machine, the gain in information is stationary (and a maximum)
if the parameter's values are distributed independently of the machine's. Information in machines Markov process / chain affecting a machine
Summary: (Stated at the front - on 3218): If a machine is driven by an absolute system, the duration of coupling makes no
difference to the amount of information received. Information in machines Markov process / chain affecting a machine
Summary: An information source controlling an otherwise absolute system raises it to a definite
information content at which it is in stable equilibrium. (3086) (Canonical equations next page) Information in machines Markov process / chain affecting a machine
