The philosophical analysis of phenomena surrounding and shaping the human environment reveals the essence of processes and their structure. Through philosophical methods of cognition, we have the opportunity to elucidate the further possible development of humanity as a whole and of specific countries and societies. Every sphere of activity in human culture has not only undergone professional diversification but is also represented by such concepts as “expert” and “specialist.” Like all of science in general, each individual concept and phenomenon, as a result of the joint action of culture and civilizational processes, acquire new meanings and understandings. Unfortunately, however, there is often a certain “forgetting” of the basic constants of their original significance and an substitution (imitation of activities, phenomena, social practices, etc.). Therefore, the urgent step is to turn to the analysis of primary sources, among which, in the contemporary space of war, the concepts of “expert” and “specialist” are paramount. The dismissive attitude towards military specialists, for which the later years of the Soviet Union were notorious, had a significant negative impact on the societies of the post-Soviet space. Therefore, with the materials of our research, we take what may be the first step toward analyzing the concepts and restoring respectful attitudes towards military specialties of all profiles. We continue to investigate not only war (pre-war, war, and post-war periods) but also the state and characteristics of the spiritual and professional spaces of people, both military and civilian. The goal is to lay the foundation for preserving the spiritual and practical achievements of Ukrainians, thanks to which, at the cost of immense sacrifices, our State is maintained, and the possibility to write these lines exists. War and post-war periods are a collective action of citizens in the broadest possible spheres, taking into account the consequences and causes of war as a phenomenon and phenomenon. Both war and post-war periods require new specialists for a range of professions and rehabilitation techniques. The aim of a just war is to protect and strive to restore both the state integrity and rehabilitate citizens to the maximum possible previous spiritual and physical integrity. The proposed article is dedicated to reflecting on this issue.
