The process of empirical substantiation of management activity in the context of existing requirements for ensuring the development of the public sphere is investigated. The relevance and necessity of such a justification is due to a number of postmodern factors, in particular, such characteristics of the indicated activity as versatility of implementation and direction, significant uncertainty of the premises, poly-subjectivity and value of reaching consensus. The essence of empirical substantiation is defined as the process of establishing the reliability of knowledge about the initial situation by applying a number of proven methods and measures. The difficulty of such an establishment is due to the fact that there is a fundamental opposition between knowledge and the real situation of objects reproduced by it. The justification of the reliability of empirical knowledge differs from the data similar to the content of scientific research and verification of data, since it includes taking into account the significance of the subject given to the subject of managerial activity. Given the subject-object nature of the latter, its empirical substantiation is carried out using a combination of natural science and humanitarian postmodern approaches. The position is substantiated that intersubjective certainty fundamentally differs from subjectivity and the lines of their distinction are drawn.

The major purpose of the study is to characterise the philosophy of the functioning of the world in such conditions. Methodology of this article included: general scientific methods (formal-logical, systemic, structural-functional, concrete-historical) general logical methods of theoretical analysis (analysis, synthesis, generalisation, comparison, abstraction, analogy, modelling, etc.) specific scientific methods (technical analysis, specification, interpretation, etc.). As a result of the study, the philosophical and social essence of the crisis and pandemic was characterised. Considered how the crisis and pandemic affect the functioning of the suspension and its philosophy of worldview. Determined how strong the impact of COVID-19 and the crisis it has formed. The philosophical and social aspect of the pandemic in modern conditions of development and what new globalisation challenges it entails has been investigated.
