Re: Peirce List • Helmut Raulien

In systems theory and engineering there is a well-recognized duality or complementarity between the dimensions of Control and Information, frequently cast in terms of action and perception, actuators and detectors, effectors and sensors, and a variety of other aliases.  There we find the dual devices of reachability matrices, representing the operations it takes to put a system in a given state, and observability matrices, representing the operations it takes to identify a system as being in a given state.

The appearance of matrices at this point, understood in the sense of 2-dimensional arrays of coefficients, may give us a clue to the dyadic character of the analysis and design models issuing from them.  And yet there is every opportunity in systems theory and engineering to open up the additional “elbow room” that triadic relations provide.
