This short note from April 1962 analyzes the cybernetic concept of 'variety' as defined by W. Ross Ashby in his seminal work. The author highlights Ashby's thesis that variety is not an intrinsic property of a set but is determined by the observer's powers of discrimination. Two distinct definitions of variety are presented: the total number of distinct elements and its logarithm to the base two. Based on these definitions, the author critically re-evaluates the arguments of Jiří Zeman. The text suggests that if variety is observer-dependent, it is impossible to directly compare the variety of objective reality with that of a perceiving subject. Instead, one should compare the variety of input information with the variety of the resulting knowledge. The document concludes by identifying a broader, unresolved epistemological problem regarding the emergence of information as such. This reflection illustrates the historical engagement of Czech philosophy with early cybernetic theory and its implications for the theory of knowledge.
