The aim of the book is to examine the ways in which conflict can originate and develop and to point out how it can deescalate on the basis of a conscious grasp of one’s own existence. Humanity plays a key role in this process. The basis for the presented reflection are ideas of thinkers belonging to the intellectual paradigms of philosophy of existence and conservative revolution: S. Kierkegaard, M. Buber, M. Heidegger, C. Schmitt, and E. Jünger. The common denominator of their thought is the interpretation of existence as both a given and a task. The monograph focuses on the latter moment when existence is realized as self-formation of the individual and the collective. This includes a conscious relation to one’s enemy with the goal of overcoming concrete enmity. In the political sphere the principle of humanity emphasizes the anthropological equality of the conflict’s participants. It forms the basis for the implementation of systematic limitation of enmity, which by means of clear distictions and rules prevents the degradation of the adversary and the absolutization of enmity. Existential self-formation enables the individual to apply this principle as an antidote to mass propaganda that discriminates the enemy. The possibility of consciously choosing one’s existence is present even in the moments of intensive leveling. Such a choice includes rootedness in fundamental existential relationships and its key expression is humanity.
