Quantity - quality - measure in the context of digital reality
Subject. The issues of measure as the basis of a new approach to the knowledge of things, which manifested itself in the 21st century, are revealed and conceptually worked out. The purpose of the work is to substantiate the definitions of «quantity» and «quality» in the context of digital reality. Method or methodology. The methodological support in modern knowledge and practice is the recognition of four independent foundations, equally necessary for an adequate comprehension of the essence of phenomena, the objective world in local and global aspects. This is matter, consciousness (idea), information (in its dual sense) and measure (harmony) - the universal equivalent of everything. The results of the work. The transition to systems of multiplicity, synthesis, integration is one of the main aspects of the development of the immediate ion of cognition. The main tool is the golden sections as the dominant line of various kinds of research programs, especially the means of constructing criteria for optimal economic development. Conclusions. In the course of the research, the approach to the management of complex dynamic systems has been rethought, in particular, the understanding of the specifics of predicting subsequent states based on information about the previous state has been expanded, the key philosophical and methodological aspects of managing the dynamics of the structure of complex systems have been highlighted, and a close connection between the phenomena of «measure» and «efficiency» has been established.
