"The ultimate inadequacy of any control language to perform its task can be remedied by the technique of inserting a black box in the control circuit" (After S. BEER, 1971, p.81).
The ultimate inadequacy referred to by BEER is, as he himself states, a result from GÖDEL's Incompleteness Theorem. His principle is based on the idea that: "The function of the back box is precisely to invoke the decisions of a higher language, which of course cannot by definition be expressed in terms of the control language, to repair the deficiencies of the original decision-making machine& The undecidable language is to be keyed in" to the real life it seeks to describe by an inherently indefinable black box" (Ibid).
This should be compared with J.van GIGCH's concept of metasystem and its use for "decision making about decision making" (1986).
