Abstract
Purpose Ranulph Glanville has argued that ambitions of strict control are misplaced in epistemic processes such as learning and designing. Among other reasons, he has presented quantitative arguments for this ethical position. As a part of these arguments, Glanville claimed that strict control even of modest systems transcends the computational limits of our planet. The purpose of this paper is to review the related discourse and to examine the soundness of this claim. Design/methodology/approach Related literature is reviewed and pertinent lines of reasoning are illustrated and critically examined using examples and straightforward language. Findings The claim that even modest epistemic processes transcend the computational means of our planet is challenged. The recommendation to assume out-of-control postures in epistemic processes, however, is maintained on ethical rather than on quantitative grounds. Research limitations/implications The presented reasoning is limited in as far as it is ultimately based on an ethical standpoint. Originality/value This paper summarizes an important cybernetic discourse and dispels the notion therein that epistemic processes necessarily involve computational demands of astronomical proportions. Furthermore, this paper presents a rare discussion of Glanville’s Corollary of Ashby’s Law of Requisite Variety.

Efficient control depends on requisite variety between the controller and the controlled
Summary
Bremermann (1962) describes an in-principle limitation of computability resulting from the finite availability of potentially computation-carrying physical matter. Beyond this so-called Bremermann’s Limit, computational problems are considered transcomputable, i.e. unsolvable within the material and temporal means of our planet. Since Ashby proposed a connection between transcomputability and systemic control in 1964, references to Bremermann’s Limit are frequently featured in cybernetic discourse The full terms of this licence may be seen at http://creativecommons.org/licences/by/4.0/legalcode
