Also, I would like to apply the frame of the existential philosophy. First of all, I would like to appeal to the notion of the “Dasein” (M. Heidegger) as a “rooting-in into the national being” (P. Ivanyshyn, T. Shestopalova, O. Vertii) because the Ukrainian literature of the period of the war represents the modus of national being via the phenomenon of the fundamental existential choice, which is nation-centric, which predicts the re-birth of the noble, knight culture (nobility in the Ukrainian mentality means the readiness to defense your people and your country).
The existential optics demands also the thinking about the values and about the spirituality. I suppose that the key existentials of the Ukrainian being (and the Ukrainian literature) of this war are the existential of freedom and the existential of love because love makes us free, responsible, and ready to fight for our future.
